Currently, almost all MT63XX PMIC are documented mfd/mt6397.txt. Unfortunately, the PMICs haven't always similar HW sub-features. To have a better human readable schema, I chose to make one PMIC schema to match the exact HW capabilities instead of convert mt6397.txt to mediatek,mt63xx.yaml and put a bunch of properties behind "if contain ... then ..." - add interrupt property - change property refs to match with new yaml documentation Signed-off-by: Alexandre Mergnat <amergnat@baylibre.com> --- .../devicetree/bindings/mfd/mediatek,mt6357.yaml | 102 +++++++++++++++++++++ 1 file changed, 102 insertions(+)
