[PATCH V3 0/4] Add Anbernic RG35XX-SP

[PATCH V3 0/4] Add Anbernic RG35XX-SP

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Add support for the Anbernic RG35XX-SP handheld gaming device. The
Anbernic RG35XX-SP is a clamshell device, but hardware wise is very
similar to the RG35XX-Plus. The RG35XX-SP has a lid-switch and an
external RTC that necessitate a distinct device tree.

Please note that this series may have a soft pre-requisite on the patch
series here [1].

[1] https://lore.kernel.org/linux-sunxi/20240418000736.24338-1-andre.przywara@arm.com/

Changes from V2:
 - Corrected commit message for device tree bindings.
 - Added a fixes tag to i2c pinmux additions in sun50i-h616.dtsi file
   based on recommendation from Andre Przywara.

Changes from V1:
 - Switched all RG35XX devices from the r_rsb bus to the r_i2c bus for
   the PMIC to keep it consistent.
 - Added missing pinctrl nodes in sun50i-h616.dtsi file for the r_i2c
   bus.
 - Modified devicetree documentation to keep definition of the RG35XX
   series consistent with other Allwinner devices.

[PATCH V3 1/4] dt-bindings: arm: sunxi: Add Anbernic RG35XXSP

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Add the Anbernic RG35XXSP variant device.

The Anbernic RG35XXSP is almost identical to the RG35XX-Plus, but in a
clamshell form-factor with an external RTC and a lid switch.

[PATCH V3 2/4] arm64: dts: allwinner: h616: Add r_i2c pinctrl nodes

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Add pinctrl nodes for the r_i2c node. Without the pinmux defined the
r_i2c bus may fail to work, possibly if the bootloader uses rsb mode
for the PMIC.

Fixes: 0d17c8651188 ("arm64: dts: allwinner: Add Allwinner H616 .dtsi file")

[PATCH V3 3/4] arm64: dts: allwinner: h616: Change RG35XX Series from r_rsb to r_i2c

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Change the Anbernic RG35XX series to use the r_i2c bus for the PMIC
instead of the r_rsb bus. This is to keep the device tree consistent
as there are at least 3 devices (the RG35XX-SP, RG28XX, and RG40XX-H)
that have an external RTC on the r_i2c bus.

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

The Anbernic RG35XXSP is almost identical to the RG35XX-Plus, but in a
clamshell form-factor. The key differences between the SP and the Plus
is a lid switch and an RTC on the same i2c bus as the PMIC.

The change itself looks alright, but I would like to see some Tested-by:s
from people with those Allwinner Anbernic devices, since the change affects
all of them.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade

That is a problem of an existing .dts files in the tree, namely
sun50i-h700-anbernic-rg35xx-2024.dts. It describes the "boost" regulator,
but the three patches adding that didn't make it in this time.
So how do we deal with that? 
This small binding patch would solve this particular problem:
https://lore.kernel.org/linux-sunxi/20240418000736.24338-4-andre.przywara@arm.com/
It has an ACK from Lee and Krzysztof, but I guess it's too late now for
6.10? Do we just ignore it for now and push it as a fix after -rc1?

Cheers,
Andre

Tested on RG35XX-H and RG35XX-Plus devices, confirmed AXP717 detected and configured using I2C bus by both kernel and u-boot. 

Also note this change corrects reboot behaviour on battery-based devices, where the AXP717 is not reset (and so remains in RSB mode) and is unable to be addressed by the u-boot SPL driver (which is I2C-only) on restart. Using I2C for all accesses prevents this behaviour.
