[PATCH 0/2] Add PM8008 regulator support for Fairphone 4 & 5

[PATCH 0/2] Add PM8008 regulator support for Fairphone 4 & 5

[Luca Weiss]

With the PM8008 regulator driver scheduled for Linux v6.11[0] let's add
the dts bits for Fairphone 4 and Fairphone 5 which both use this PMIC
for powering the camera sensors - and the pull-up for the CCI (camera
I2C bus).
