[PATCH v4 8/9] arm64: dts: allwinner: add Allwinner H5 .dtsi

Icenowy Zheng icenowy at aosc.xyz
Tue Feb 7 10:30:41 PST 2017


From: Andre Przywara <andre.przywara at arm.com>

The Allwinner H5 SoC is pin-compatible to the H3 SoC, but uses
Cortex-A53 cores instead.
Based on the now shared base .dtsi describing the common peripherals
describe the H5 specific nodes on top of that.
That symlinks in the sunxi-h3-h5.dtsi from the arch/arm tree.

[Icenowy: add H5 pinctrl compatible, and changes for my h3-h5 dtsi
 refactor, commit message change to met new arm64 naming scheme,
 drop H3 pinctrl compatible because of interrupt bank change, drop
 H3 ccu compatible because of clock change]

Changes in v3:
- Dropped sun5i-a13-mmc, sun8i-h3-ccu compatibles.
- Used sun50i-{h5,a64}-emmc compatible for mmc2.
Changes in v2:
- Dropped sun8i-h3-pinctrl compatible, as the interrupt of H3 and H5 is
