[PATCH 0/3] arm64: dts: rockchip: rk3328-roc-cc: Misc improvements

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

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

[PATCH 1/3] arm64: dts: rockchip: rk3328-roc-cc: Set dr_mode to "host" for OTG

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

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.

[PATCH 2/3] arm64: dts: rockchip: rk3328-roc-cc: Enable HDMI audio

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

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.

[PATCH 3/3] arm64: dts: rockchip: rk3328-roc-cc: Enable analog audio

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

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.
