Most drivers aren't even available in 4.4.x, and some aren't even in
4.5.x yet. From a breif glance, the dts files for
arch/arm64/boot/dts/hisilicon/hi6220*, don't look to contain support for
much more than the CPU, memory and serial...

Reading that patch, I'm guessing the following are available and
possibly needed or desired, though possibly may require device-tree
patches as well:

available in 4.4.x:

CONFIG_ARCH_HISI=y
CONFIG_POWER_RESET_HISI=y
CONFIG_HISI_THERMAL=m
CONFIG_MMC_DW=m
CONFIG_MMC_DW_K3=m
CONFIG_I2C_DESIGNWARE_PLATFORM=m

available in 4.5.x:

CONFIG_COMMON_RESET_HI6220=m
CONFIG_PHY_HI6220_USB=m

linux-next tag next-20160311:

CONFIG_HI6220_MBOX=m
CONFIG_REGULATOR_HI655X=m


Will build a few test kernels and report back...

[PATCH/sid v3] Build tools from power/cpupower

[malattia]

From: Mattia Dongili 

They'll eventually replace cpufrequtils and libcpufreq{0,-dev} so the
structure of the packages is the same.

We haven't backported any such improvements from 4.1, unless they came
through the stable process.

If you can identify specific changes that should be backported, please
open a bug report against src:linux, version as above, requesting that
we do that.

Bug#817874: linux-image-3.16.0-4-amd64: 3.16.7-ckt25-1 freeze with radeon driver

[Michael Lange]

Package: src:linux
Version: 3.16.7-ckt25-1
Severity: important

Dear Maintainer,

the day before yesterday apt-get update && apt-get upgrade upgraded the kernel
package to version 3.16.7-ckt25-1 from jessie-proposed-updates. When I booted
this kernel yesterday for the first time I experienced sudden "freezes" of the
system that made the machine completely unusable. After some investigating I
found that apparently a newly introduced bug affecting the radeon driver caused
this. The following stack trace was found in the syslog:
