This backports multiple patches from kernel 4.10 which are adding missing support for the A64 and the pine64 board. These are the device tree files, the pinctlk and the clock driver. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

Subject: arm64: dts: add Allwinner A64 SoC .dtsi
|
|
|
|
The Allwinner A64 SoC is a low-cost chip with 4 ARM Cortex-A53 cores
|
|
and the typical tablet / TV box peripherals.
|
|
The SoC is based on the (32-bit) Allwinner H3 chip, sharing most of
|
|
the peripherals and the memory map.
|
|
Although the cores are proper 64-bit ones, the whole SoC is actually
|
|
limited to 4GB (including all the supported DRAM), so we use 32-bit
|
|
address and size cells. This has the nice feature of us being able to
|
|
reuse the DT for 32-bit kernels as well.
|
|
This .dtsi lists the hardware that we support so far.
