[PATCH 0/4] Miscellaneous fixes for Odroid Go Advance

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

This series is for a bunch of trivial changes to the Odroid Go
Advance to clean up some errors in the dmesg log and make it
easier to support with alsa ucm.

[PATCH 1/4] arm64: dts: rockchip: Change audio card name for Odroid Go

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Change the audio card name for the Odroid Go Advance series to
rk817_int. This matches the audio card name of the Anbernic RG353V.
This is done to provide a consistent card name so that a single ALSA
UCM file can be used for all (identical) implementations of this codec
and configuration combo. The rk817_int configuration is for when the
internal speaker amplifier of the rk817 is used. The other Anbernic
devices have the name as rk817_ext for when an external speaker
amplifier is used.

[PATCH 2/4] arm64: dts: rockchip: don't set cpll rate for Odroid Go

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

The Odroid Go Advance devicetree tries to set the rate for the cpll
clock to 17MHz, which is not a supported rate. This fails, and triggers
the error of "clk: couldn't set cpll clk rate to 17000000 (-22),
current rate: 17000000" in the dmesg log. Remove the incorrect rate.

[PATCH 3/4] arm64: dts: rockchip: update px30 thermal zones for GPU

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Without the trips, the following errors are received in the dmesg
log and the rockchip-thermal driver fails to load the gpu sensor:

"thermal_sys: Failed to find 'trips' node"
"rockchip-thermal ff280000.tsadc: failed to register sensor 1: -22"

Trip values are assumed, unfortunately, as the same values as the
CPU. The datasheet and TRM didn't appear to have any information
regarding thermals for the GPU.

Stress tested successfully on my Odroid Go Advance.

[PATCH 4/4] arm64: dts: rockchip: Update leds for Odroid Go Advance

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Update the blue LED to be controlled via pwm to enable control of LED
brightness. Add red LED as a GPIO controlled LED. The documentation
stated "label" was depreciated so function and color was used instead.
The LED names (led-2 and led-3) are given because that is what they
are numbered on the board itself; LED 1 is wired directly into an
always on regulator and is not controllable. LED 2 is labelled "alive"
on the board and documentation recommends we set the function as
status over other miscellaneous functions. LED 3 is labelled "chg" on
the board.
