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

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?
