arm64: dts: rockchip: rk3328-roc-cc: Misc improvements

From: Chen-Yu Tsai <[email protected]>

Hi,

Here are some improvements for the ROC-RK3328-CC.

Patch 1 sets dr_mode to "host" for OTG. Since the board has a type A host port wired to the OTG controller, setting this is appropriate.

Patch 2 enables HDMI audio.

Patch 3 enables analog audio.

I opted to use one simple-card for each audio interface since a) the definitions are already in the .dtsi file and b) having one card per interface with proper names makes them easier to identify.

The changes are quite trivial. Hope they can be merged for the next release.

Regards
ChenYu

The board has a standard USB A female port connected to the USB OTG controller's data pins. Set dr_mode in the OTG controller node to indicate this usage, instead of having the implementation guess.

The RK3328-ROC-CC already has HDMI display output enabled. Now that audio for the HDMI controller is supported, it can be enabled as well.

Enable the simple-audio-card, and the I2S interface the audio is fed from.

Now that driver support for the RK3328's audio codec, and the plumbing is defined at the SoC level, we can enable analog audio at the board level.

Enable analog audio by enabling the codec and the I2S interface connected and the simple-audio-card that binds them together.
