Bug#990536: linux: Please enable RK805 PMIC components for Rock64 SBC.
Source: linux
Version: 5.10.46-1
Severity: wishlist
Tags: patch
On Pine64's Rock64 SBC the RK805 Power Management IC is used, but it's
not enabled in arm64's config, so hereby the request to enable it.
It's about the following 2 settings:
- CONFIG_PINCTRL_RK805=y
- CONFIG_INPUT_RK805_PWRKEY=m
With those 2 settings enabled on an upstream kernel, the LEDs went from
always on to reacting as it is defined in the DeviceTree, which is
'mmc0' and 'heartbeat'. It also made /sys/devices/platform/leds/leds/
available which allows one to configure the trigger.
Attached is the patch I applied to the upstream kernel source.
Regards,
Diederik

Subject: [PATCH 4/4] Enable Power Management ICs for RK805 components.
https://www.cnx-software.com/pdf/Rockchip-Roadmap-2019-.11_mts.pdf
says on page 3 that RK805 is used for RK3328/RK3228 SOCs and
Pine64's Rock64 is a SBC that uses that.
The PINCTRL_RK805 makes the LEDs work on the Rock64 and can be
managed/configured via /sys/devices/platform/leds/leds/.
The default is as configured in the DeviceTree.
There's (apparently) also a power button on the Rock64 and the
INPUT_RK805_PWRKEY is the module through which one can enable it.
