[PATCH v1 04/13] arm64: dts: rockchip: rock-5a: add vdd_cpu_big regulators

[Sebastian Reichel]

The RK8602 and RK8603 voltage regulators on the Rock 5A board provide
the power lines vdd_cpu_big0 and vdd_cpu_big1, respectively.

Add the necessary device tree nodes and bind them to the corresponding
CPU big core nodes.

[PATCH v1 08/13] arm64: dts: rockchip: rock-5a: add analog audio

[Sebastian Reichel]

Add analog audio support based on the Everest Semi ES8316 codec.

Note, that this currently does not support headphone plug events. The
Rock 5A uses a different headphone jack with a different logic to detect
a headphone plug. Unfortunately the detect GPIO is always low.
Downstream uses an ADC channel instead, but that is currently not
supported upstream.

Applied, thanks!

After talking with Arnd on IRC, I also picked the two binding patches
for the eeprom.

I also fixed a number of nits when applying:
- "-regulator" suffix was missing on most added fixed regulators
- one regulator@42 was instead a rk6*@42
- some ordering issues
