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.

>From 3613d72806d37dcb7812c55513fcf232afb7746f Mon Sep 17 00:00:00 2001 From: Diederik de Haas <didi.deb...@cknow.org> Date: Sun, 23 May 2021 23:53:22 +0200 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.
