Subject: Re: [PATCH v2 5/8] arm64: dts: add Allwinner A64 SoC .dtsi

Just saw that I forgot the Changelog, sorry about that.

Changelog v1..v2:
- remove compatible string from the .dtsi
- amend compatible names to include sun50i
- drop PSCI 0.1 compatibility
- use lowercase hex digits in the GIC node too
- make pll6x2 an explicit fixed-factor clock
- make pll8 and pll8x2 proper clocks
- amend MMC clocks to match the manual, they are now mod0 clocks
- adapt MMC nodes to new MMC clocks
- add separate 4-pin and 2-pin definitions for the UARTs
- add I2C pins and driver nodes
- switch ahb_rst node to use normal compatible name, not the special,
  early-registration one.

Cheers,
Andre.
