That said, I have been fighting issues from this patchset when trying to read from devices on the i2c0 bus on a RK3399—which had me add a “simple” pinctrl device again, as pulling all the dependencies into the SPL is a pain.
I think you can also add the simple ops if necessary. Full pinctrl should only be used at the U-boot stage, or the SPL stage where the TPL is available.
For most boards about 3288, there is no need to enable pinctrl at SPL stage, such as Tinker board.
Unfortunately, in this merge I had to make a judgement call between insisting on code-quality and getting the full pinctrl-driver merged. With this release cycle being longer and having 5 RCs, I figured we’ll have time to iron out any wrinkles...
