Add Support for RK3588s Indiedroid Nova

From: Chris Morgan <[email protected]>

Add support for the RK3588s based Indiedroid Nova. Note that this series is dependent on regulator support for the RK806 being upstreamed.

https://lore.kernel.org/linux-rockchip/[email protected]/

Changes Since V1:
- Removed changes to ES8328 codec and added a note that a permanent fix will be needed to cope with a 1hz mismatch between requested frequency and actual frequency.
- Fixed vendor-prefixes.yaml change to alphabetical order.

Resending as my previous email probably got lost. If you got it twice, apologies.

2.34.1

From: Chris Morgan <[email protected]>

The Indiedroid Nova is an SBC from a sub-brand of Ameridroid that includes the following hardware:

- A 40-pin GPIO header
- 2 USB-A 3.0 ports
- 2 USB-A 2.0 ports
- A USB-C 2.0 OTG port (used for USB power delivery)
- A USB-C 3.0 port that can do display port output.
- A Micro HDMI 2.1 port.
- A 1GB ethernet port.
- An RT8821CS based WiFi/Bluetooth module.
- A user replaceable eMMC module.
- An SDMMC card slot.
- A MIPI DSI connector.
- A MIPI CSI connector.
- A 3.5mm TRRS audio jack with microphone input.
- An 2 pin socket for an RTC battery.
- A 4 pin socket for a debug port.
- A power button (connected to PMIC), a reset button (connected to SoC reset), a boot button, and a recovery button (both connected to the ADC).
- 4GB, 8GB, or 16GB of system RAM.

This initial devicetree includes support for the WiFi, bluetooth, analog audio out/in, SDMMC, eMMC, RTC, UART debugging, and has the regulator values from the schematics. ADC, graphics output, GPU, USB, and wired ethernet are still pending additional upstream changes.

Analog audio will require changes to handle a difference between the requested clock frequency of 12288000 and the actual clock freqency of 12287999 before it will work properly. This will be done in a subsequent patch series.

Dropped a double empty line and adapted the fixed regulators to add the "foo-regulator" suffix to them.
