[PATCH V2 0/3] Indiedroid Nova Audio/HDMI Updates

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

This series is for a handful of fixes and updates for the Indiedroid
Nova. This series corrects the device name of the audio card to stop
a kernel log error, and adds support for both the HDMI and GPU (now
that HDMI support has been queued for linux-next).

Changes since v1:
 - Corrected HDMI port from mini HDMI (c) to micro HDMI (d).
 - Explained why I enable hdmim0_rx_hpdin in contrast to the other
   rk3588 boards.
 - Split HDMI0 and GPU patches into different patches.

[PATCH V2 1/3] arm64: dts: rockchip: correct analog audio name on Indiedroid Nova

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Correct the audio name for the Indiedroid Nova from
rockchip,es8388-codec to rockchip,es8388. This name change corrects a
kernel log error of "ASoC: driver name too long 'rockchip,es8388-codec'
-> 'rockchip_es8388'".

[PATCH V2 3/3] arm64: dts: rockchip: Enable HDMI0 on Indiedroid Nova

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Enable the HDMI0 port for the Indiedroid Nova. The schematics available
show the hdmim0_rx_hpdin is connected, so this pinctrl is enabled in
contrast with the other rk3588 boards.

Which pin in the schematic [1] (page 24) does it refer to? It's not
obvious how to match it up.
The schematic looks the same as the Rock 5B schematic [2] (page 31)
and the Rock 5B dts uses the default pinctrl [3]

Note: The vendor kernel DTS doesn't modify the pinctrl either. [4]

If you try using the default pinctrl (not overriding), does HDMI not work?

I stumbled over the same issue recently for our Theobroma boards too.

From the Indiedroid schematics, you can see that the hdmim0_rx_hpdin
pin is gpio4_b6, which in their board is connected to the hdmi0_tx_on_h
functionality, which controls the output functionality between hdmi2.0-tmds
and hdmi2.1-frl modes.

The hdmi-driver currently only does hdmi2.0 but normally, on most boards
I've seen so far, this pin has a default pull to set hdmi2.0 anyway, so other
boards don't need that.

So for one, please check if the nova can run without it, but if a pin
setting is needed, please define a new per-board one, labeling it correctly
for this hdmi0_tx_on_h functionality and do not re-use the hdmi-rx
pin-setting.


Heiko

I can confirm it will run without it, so I'll simply set the pinctrl to
be the same as the other boards.

Thank you,
