Commit Message

Sept. 19, 2023, 10:43 a.m. UTC
The MT6366 PMIC is mostly, but not fully, compatible with MT6358. It has
a different set of regulators. Specifically, it lacks the camera related
VCAM* LDOs and VLDO28, but has additional VM18, VMDDR, and VSRAM_CORE LDOs.
The PMICs contain a chip ID register that can be used to detect which
exact model is preset, so it is possible to share a common base
compatible string.
Add a separate compatible for the MT6366 PMIC, with a fallback to the
MT6358 PMIC.
Fixes: 49be16305587 ("dt-bindings: mfd: Add compatible for the MediaTek MT6366 PMIC")
