From d8f083a302f7f69eecd513ce1aa828cfff41f0cf Mon Sep 17 00:00:00 2001 From: Soeren Moch Date: Sun, 12 Jan 2020 01:55:00 +0000 Subject: mfd: rk808: Always use poweroff when requested With the device tree property "rockchip,system-power-controller" we explicitly request to use this PMIC to power off the system. So always register our poweroff function, even if some other handler (probably PSCI poweroff) was registered before. This does tend to reveal a warning on shutdown due to the Rockchip I2C driver not implementing an atomic transfer method, however since the write to DEV_OFF takes effect immediately the I2C completion interrupt is moot anyway, and as the very last thing written to the console it is only visible to users going out of their way to capture serial output.
