Patch: STK3310 as module, AXP20X_POWER built in #2

Closed nxdefiant closed 2 years ago

nxdefiant commented 2 years ago

When the stk3311 light & proximity sensor of the pinephone is build into the kernel, the i2c communication with it fails. This is probably because the stk3311 is powered by the PMIC (gpio0-ldo) which is not fully initialized at this time.

The settings CONFIG_STK3310=m and CONFIG_AXP20X_POWER=y are also used by the Megi kernel.

The other changes, e.g. VIDEO_SUN6I_CSI=y -> m have been automatically done by menuconfig and do look correct since some if its requirements are =m, I can revert them if requested.

To test: /sys/devices/platform/soc/1c2b000.i2c/i2c-1/1-0048/iio:device3/in_proximity_raw and /sys/devices/platform/soc/1c2b000.i2c/i2c-1/1-0048/iio:device3/in_illuminance_raw should both be there

This looks good, thanks. I'll merge and build in a bit.
