It's not clear to me that these modes are a useful thing to be exposing in device tree - they've always been rather arbatrary and are becoming less and less relevant as regulator hardware improves in its ability to adapt to load. I think for fixed modes that don't vary dynamically at runtime the best thing is just to make the modes custom so they map onto the device datasheets clearly. That seems to be most of the usage anyway. [unhandled content-type:application/pgp-signature] | |
