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 Reviewed-by: Krzysztof Kozlowski Signed-off-by: Alexandre Mergnat --- .../devicetree/bindings/mfd/mediatek,mt6357.yaml | 111 +++++++++++++++++++++ 1 file changed, 111 insertions(+) diff --git a/Documentation/devicetree/bindings/mfd/mediatek,mt6357.yaml b/Documentation/devicetree/bindings/mfd/mediatek,mt6357.yaml new file mode 100644 index 000000000000..837a77013d57 --- /dev/null +++ b/Documentation/devicetree/bindings/mfd/mediatek,mt6357.yaml @@ -0,0 +1,111 @@ +# SPDX-License-Identifier: GPL-2.0-only OR BSD-2-Clause +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/mfd/mediatek,mt6357.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: MediaTek MT6357 PMIC + +maintainers: + - Flora Fu + - Alexandre Mergnat + +description: | + MT6357 is a power management system chip containing 5 buck + converters and 29 LDOs.
