Hi, All

We now see better support for HiKey in v4.7-rc1 mainline vanilla, and following features landed in v4.7-rc1: dts, configs, pmic, and drm. Features supported from mainline kernel include:

• usb otg and host (high-speed mode)
• microSD card
• uart on Low-speed expansion port (LS)
• I2C on LS
• SPI on LS
• WiFi (need update UEFI to latest, see below for link)

Just for your curiosity, in v4.6, we upstreamed: usb & usb phy, (CONFIG_PHY_HI6220_USB), hi655x regulator, hi6220 mailbox, hisi reset, and mmc dw k3.

Ref: Build procedure: git checkout -b YOUR-WORKING-BRANCH v4.7-rc1 make ARCH=arm64 defconfig; export LOCALVERSION="-linaro-hikey"; make ARCH=arm64 Image modules hisilicon/hi6220-hikey.dtb -j20;

With

1. latest UEFI:

(https://builds.96boards.org/snapshots/reference-platform/components/uefi/lat...), 2. Debian rootfs: http://builds.96boards.org/snapshots/reference-platform/debian/98/hikey/

Then, replace Image and dtb, you can see v4.7-rc1 running on HiKey.

That's great news, nice to see it finally coming together with upstream.

Now we just need to fix https://bugs.96boards.org/show_bug.cgi?id=267 and upstream EDK2/UEFI, so it can be easily supported by any distro.

Cheers,
