Hi, all
Here is a summary and status report about HiKey in vanilla linux and our upstreaming plan.
As of v4.4, already upstreamed:
- clk, psci, basic dts, uart, cpufreq, cpuidle, mailbox, emmc, wifi driver fix, and tsensor (thermal)
- hikey can boot using vanilla v4.4 kernel and defconfig.
Based on v4.4, topic branches are available, and integration branch is hosted here:
- Git repo: https://github.com/96boards-hikey/linux
- Integration branch: hikey-mainline-rebase https://github.com/96boards-hikey/linux/tree/hikey-mainline-rebase
- Topics (so features) include: dts, pmic, mmc, usb, adv7511, drm, pm, gpu, bluetooth, ion, hisi-reset, hikey-configs. (Most of *these are backport of what we sent in maillist for community review.*)
- pre-builds are available too, if you just want to download and give it a try: https://builds.96boards.org/snapshots/hikey/community/hikey-mainline-rebase/
Moving onward,
v4.5-rc1:
USB: driver, 37dd9d6 usb: dwc2: add support of hi6220.
Slated for v4.6 merge-window:
hisi-reset driver: in linux-next ( http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/tree/drivers... )
DTS: in maintainer's git repo: https://github.com/hisilicon/linux-hisi
- Including: gpio, pinctrl, i2c
More work targeting v4.6:
DTS: need submit to hit v4.6: usb, mmc, wifi, and led.
pmic, regulator: sent v6 on 18/Jan. In maillist review.
- http://thread.gmane.org/gmane.linux.kernel/2129489
drm: v2 on 28/Nov. In maillist review. v3 will be sent in early Feb.
- http://www.spinics.net/lists/dri-devel/msg95283.html
adv7533: common driver with qualcomm dragonboard, investigations ongoing to have a single driver
Work in progress that might miss 4.6:
mmc: by early Feb., to send v1 of patch to mailing list.
-
clk: hi6220: register reset clocks for mmc: (will drop. Need re-write to use hisi-reset framework which exists in linux-next.) -
mmc: dw_mmc: hikey: add this support for high speed sd card (will refactor and send maillist).
Idle and mailbox: Reserve memory regions and enabling idle states: Resend V2 after alignment with DT maintainers:
Mailbox V3 sent out for review and discussed at Connect [2015/Oct].
- [2016/1/29] two steps:
1) add dts for reserving memory regions and enabling idle states; because MCU is quite depend on memory regions, otherwise it will introduce unstable issue for mailbox driver as well. This step targets v4.6.
2) add mailbox driver.
coresight: [2016/1/29] in v4.4, etm0 is ok. etm1~7 can cause system hang - still under investigation.
smmu: V2 [2015/Oct.]: http://thread.gmane.org/gmane.linux.ports.arm.kernel/449391
- Actually we want to combine ION and smmu together. Now ION code is not ready yet.
bluetooth: TI's driver is not fully upstreamed. Need to enable with additional patches. (Enabled on v4.4 kernel.)
HDMI audio: in-progress. v3.18 was added. v4.4 not added yet.
- Basic function is ok, but there is noise. Need to rewrite the DMA driver.
Thanks for the update, Guodong.

I know you could use some help rewriting this DMA driver to enable HDMI audio. Is there anything else on this list that is unassigned and could use some help?

Amit, this patch in dw_mmc is a hard one. ( https://github.com/96boards-hikey/linux/commit/2a8f3eb55492f5c228a0247b8981b...). It's hard to upstream this. But due to some silicon restrictions (I am asking for more about what that means, sorry), on v4.4, we need to add this change to make sd card work on HiKey. But this commit changed the dw_mmc core code, which is bad.

Hi Guodong,
Can you enable i2c0 and i2c1 in these builds please? They are needed for working with mezzanine boards. I've attached an untested patch to enable it in dts. I will try to test it later today, but I've got a lot to deal with today, so it may take a few days.

Hi Guodong,
Just tested, and that worked to create the i2c devices (but I had to enable CONFIG_I2C_CHARDEV to get the userspace interface). However, i2c bus 0 and 1 aren't working. i2cdetect appears to do the right thing, but the i2c transaction isn't getting out to the external bus. Is there some pin config that needs to be adjusted for HiKey for i2c?

I just checked. The 4.4 kernel does not enable the 1.8V voltage rail on the LS expansion connector. Do you know how to enable it?

Hi Guodong,
I tried to follow step by step procedure on the User Manual on Sensor Board Rev C, and found many of the USB-Ethernet dongle are turned off compare to 3.18 release.
It would be nice if the new release will be able to work completely with the Sensor Board.
I will send you the patch.

Hi, all
Here is a summary and status report about HiKey in vanilla linux and our upstreaming plan.
As of v4.4, already upstreamed:
- clk, psci, basic dts, uart, cpufreq, cpuidle, mailbox, emmc, wifi
driver fix, and tsensor (thermal)
- hikey can boot using vanilla v4.4 kernel and defconfig.
Based on v4.4, topic branches are available, and integration branch is hosted here:
Git repo: https://github.com/96boards-hikey/linux
Integration branch: hikey-mainline-rebase
Topics (so features) include: dts, pmic, mmc, usb, adv7511, drm, pm,
gpu, bluetooth, ion, hisi-reset, hikey-configs. (Most of these are backport of what we sent in maillist for community review.)
Hi Guodong,
Can you enable i2c0 and i2c1 in these builds please? They are needed for working with mezzanine boards. I've attached an untested patch to enable it in dts. I will try to test it later today, but I've got a lot to deal with today, so it may take a few days.
Updated. Thanks Grant for reminding me this.
To git@github.com:96boards-hikey/linux.git -> hikey-mainline-rebase (forced update)
Build command goes: make ARCH=arm64 defconfig; make ARCH=arm64 Image modules -j20; make ARCH=arm64 hisilicon/hi6220-hikey.dtb
-Guodong
Hi Guodong,
Just tested, and that worked to create the i2c devices (but I had to enable CONFIG_I2C_CHARDEV to get the userspace interface). However, i2c bus 0 and 1 aren't working. i2cdetect appears to do the right thing, but the i2c transaction isn't getting out to the external bus. Is there some pin config that needs to be adjusted for HiKey for i2c?
I just checked. The 4.4 kernel does not enable the 1.8V voltage rail on the LS expansion connector. Do you know how to enable it?

I would like to see if we could have such options available as a config fragment instead, and I know Amit is also working on getting a new kernel config fragments tree in place.
The other question I had, for which tree/branch are you targeting this patch?

I also prefer this to be included to Amit's work.

Hi Guodong,
I found that after the git pull today from https://github.com/96boards-hikey/linux it fails to build just because CONFIG_MODULES=y is missing.
I will send you the patch.

No, Akira. We don't need this.
To build a kernel for debian, you do (NOTE: defconfig): export LOCALVERSION="-linaro-hikey" make distclean; make ARCH=arm64 defconfig; make ARCH=arm64 Image modules -j20; make ARCH=arm64 hisilicon/hi6220-hikey.dtb
And, hikey_defconfig is a config fragment for Android which needs to be used together with defconfig.

I would like to see if we could have such options available as a config fragment instead, and I know Amit is also working on getting a new kernel config fragments tree in place.
The other question I had, for which tree/branch are you targeting this patch?
This patch was made against the first postage from Guodong,
Based on v4.4, topic branches are available, and integration branch is hosted here:
- Git repo: https://github.com/96boards-hikey/linux
- Integration branch: hikey-mainline-rebase
I also prefer this to be included to Amit's work.
It already is[1]. And they're already modules as Grant requested.
Would like to avoid adding similar patches every time on every HiKey release.
Now I'm working to separate out this functionality into config fragments (as changes on top of linux-linaro configs). Here is a draft[2] of what that might look like. So far I've only focused on core kernel features. I need to separate out the drivers out into their own fragments next (e.g. common-usb-modules, sound, filesystems-extra) after I'm done publishing a stable consolidated 4.4 kernel.
There is also the question of how can someone import these fragments into their own trees efficiently. I'm think makefile targets for common cases (e.g. 96boards, enterprise, mobile) that merge a given set of fragments together. But other ideas are welcome.
Cheers, Amit

The arm64 system is likely to be used as a host computer instead of embedded devices and adding USB-Ethernet dongles to make it behave as host PC is mandatory.

Hi, all
Here is a summary and status report about HiKey in vanilla linux and
our
upstreaming plan.
As of v4.4, already upstreamed:
- clk, psci, basic dts, uart, cpufreq, cpuidle, mailbox, emmc, wifi
driver fix, and tsensor (thermal)
- hikey can boot using vanilla v4.4 kernel and defconfig.
Based on v4.4, topic branches are available, and integration branch
is
hosted here:
Git repo: https://github.com/96boards-hikey/linux
Integration branch: hikey-mainline-rebase
Topics (so features) include: dts, pmic, mmc, usb, adv7511, drm,
pm,
gpu, bluetooth, ion, hisi-reset, hikey-configs. (Most of these are
backport
of what we sent in maillist for community review.)
Hi Guodong,
Can you enable i2c0 and i2c1 in these builds please? They are needed for working with mezzanine boards. I've attached an untested patch to enable it in dts. I will try to test it later today, but I've got a lot to deal with today, so it may take a few days.
Updated. Thanks Grant for reminding me this.
To git@github.com:96boards-hikey/linux.git -> hikey-mainline-rebase (forced update)
Build command goes: make ARCH=arm64 defconfig; make ARCH=arm64 Image modules -j20; make ARCH=arm64 hisilicon/hi6220-hikey.dtb
-Guodong
Hi Guodong,
Just tested, and that worked to create the i2c devices (but I had to enable CONFIG_I2C_CHARDEV to get the userspace interface). However, i2c bus 0 and 1 aren't working. i2cdetect appears to do the right thing, but the i2c transaction isn't getting out to the external bus. Is there some pin config that needs to be adjusted for HiKey for i2c?
I just checked. The 4.4 kernel does not enable the 1.8V voltage rail on the LS expansion connector. Do you know how to enable it?
I found the root cause. There is a bug in regulator driver, which make enabling of ldo21 1.8V fail.
I fixed the issue, and together with CONFIG_I2C_CHARDEV enabled and other changes, I uploaded a new 'hikey-mainline-rebase' branch to https://github.com/96boards-hikey/linux
I2C should work for you. :)

Another found is that the pre-builds bellow seem to stop at UEFI if trying to boot from SD card with linaro rootfs.

Hi devs,
until now, I used 1.8V from the UART Debug Header to power my i2c device, because I thought it is electrically gone on my board. But after testing it with another HiKey Board (this time from LeMaker) with the same Firmware, I'm sure it has to be enabled anywhere. In the linux device tree source I found the following lines
hisilicon/hi6220.dtsi
ldo21: ldo21@a40 { regulator-compatible = "LDO21"; regulator-min-microvolt = <1650000>; regulator-max-microvolt = <2000000>; regulator-always-on; regulator-enable-ramp-delay = <120>; };But, how to do this in Bare Metal? LDO5_1V8 seems to be enabled by default but I can't find where it is done. How to configure the PMIC in early Bootloader stage?
You need to read the code in https://github.com/96boards-hikey/linux/blob/28664a33b45a52b23bd1a68b5f27a95...
Unfortunately, we provide no public document on PMIC chip (hi655x) used on HiKey. But register information can be reverse engineered from driver code above.
Eg. .enable_reg = HI655X_BUS_ADDR(ereg), \ .enable_mask = BIT(cmask), \ enable_reg is the register to write 1 to to enable a regulator. Band enable_mask is the bit for it. Each bit for one ldo.
Similarly you see the disable_reg and vreg.

Hope someone can solve this riddle for me.

It can boot to serial console with a ramdisk, nothing else. There is a serious discrepency between the features you are reporting as supported upstream and the features that are actually supported upstream, the set supported upstream is has not changed substantially since merge.
v4.5-rc1:

Again, this does not appear in the DT and is therefore unusable for anyone using mainline.
Slated for v4.6 merge-window:
hisi-reset driver: in linux-next ( http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/tree/drivers... )
This seems to already be in Linus' tree so unless some major problem is discovered it should be in v4.5.

This does not appear to be part of the kernel development process, it does not appear in -next and I can't see any prior cases where a pull request from this tree has made it into -next. I don't see that there is any reasonable expectation that anything there will make it into mainline.
Like I said above there is a big difference between what you are reporting as upstream and the features that are practically usable upstream. This is creating a lot of frustration on the part of potential users who want to work on mainline, both with the lack of features itself and with the fact that lists of supported features are typically substantially inaccurate which makes people feel they are being mislead.

The priority has to be to get things into mainline, obviously people can already do things like grab the DT from one of the vendor branches. If it's taking any substantial time to maintain that branch then at least from my point of view it'd be better spent on the actual upstreaming.

Please allow a reasonable time for review. People get busy, go on holiday, attend conferences and so on so unless there is some reason for urgency (like critical bug fixes) please allow at least a couple of weeks for review. You only posted the most recent version on Monday, this is not the only code I have to review and there have been quite a few problems with things like review comments being ignored which will tend to affect how things get prioritised.

Chenfeng, I integrated your v7 patch to HiKey. And it still has the problem reported by Grant (ldo21 1.8V never enabled).
I checked more, here is a bug fix. In one word, .enable_mask takes bit mask, not bit number.

HI Guodong,
I found another problem with the 4.4 branch on HiKey. ttyAMA2 (UART0 on the expansion port) is not working anymore.

Hi, all
Here is a summary and status report about HiKey in vanilla linux and our upstreaming plan.
As of v4.4, already upstreamed:
- clk, psci, basic dts, uart, cpufreq, cpuidle, mailbox, emmc, wifi driver
fix, and tsensor (thermal)
- hikey can boot using vanilla v4.4 kernel and defconfig.
Based on v4.4, topic branches are available, and integration branch is hosted here:
Git repo: https://github.com/96boards-hikey/linux
Integration branch: hikey-mainline-rebase
Topics (so features) include: dts, pmic, mmc, usb, adv7511, drm, pm, gpu,
bluetooth, ion, hisi-reset, hikey-configs. (Most of these are backport of what we sent in maillist for community review.)
- pre-builds are available too, if you just want to download and give it a
try: https://builds.96boards.org/snapshots/hikey/community/hikey-mainline-rebase/
Moving onward,
v4.5-rc1:
USB: driver, 37dd9d6 usb: dwc2: add support of hi6220.
Slated for v4.6 merge-window:
hisi-reset driver: in linux-next (http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/tree/drivers...)
DTS: in maintainer's git repo: https://github.com/hisilicon/linux-hisi
- Including: gpio, pinctrl, i2c
More work targeting v4.6:
DTS: need submit to hit v4.6: usb, mmc, wifi, and led.
pmic, regulator: sent v6 on 18/Jan. In maillist review.
drm: v2 on 28/Nov. In maillist review. v3 will be sent in early Feb.
adv7533: common driver with qualcomm dragonboard, investigations ongoing to have a single driver
Work in progress that might miss 4.6:
mmc: by early Feb., to send v1 of patch to mailing list.
clk: hi6220: register reset clocks for mmc: (will drop. Need re-write to use hisi-reset framework which exists in linux-next.)
mmc: dw_mmc: hikey: add this support for high speed sd card (will refactor and send maillist).
Idle and mailbox: Reserve memory regions and enabling idle states: Resend V2 after alignment with DT maintainers:
Mailbox V3 sent out for review and discussed at Connect[2015/Oct].
- [2016/1/29] two steps:
- add dts for reserving memory regions and enabling idle states; because
MCU is quite depend on memory regions, otherwise it will introduce unstable issue for mailbox driver as well. This step targets v4.6.
- add mailbox driver.
coresight: [2016/1/29] in v4.4, etm0 is ok. etm1~7 can cause system hang - still under investigation.
smmu: V2 [2015/Oct.]: http://thread.gmane.org/gmane.linux.ports.arm.kernel/449391
- Actually we want to combine ION and smmu together. Now ION code is not
ready yet.
bluetooth: TI's driver is not fully upstreamed. Need to enable with additional patches. (Enabled on v4.4 kernel.)
HDMI audio: in-progress. v3.18 was added. v4.4 not added yet.
- Basic function is ok, but there is noise. Need to rewrite the DMA driver.

I also do not see /sys/class/gpio but is this expected?
