P1 PMIC contains of regulator, pinctrl, pwrkey and rtc. P1 contains a load switch, which allows you to control whether a device is powered on (such as a MIPI screen) Signed-off-by: Troy Mitchell <TroyMitchell988@xxxxxxxxx> --- .../devicetree/bindings/mfd/spacemit,p1.yaml | 153 +++++++++++++++++++++ 1 file changed, 153 insertions(+) diff --git a/Documentation/devicetree/bindings/mfd/spacemit,p1.yaml b/Documentation/devicetree/bindings/mfd/spacemit,p1.yaml new file mode 100644 index 0000000000000000000000000000000000000000..7475d403aeb3d0e72ffa9b6fbcbb6545d5bc429f --- /dev/null +++ b/Documentation/devicetree/bindings/mfd/spacemit,p1.yaml @@ -0,0 +1,153 @@ +# SPDX-License-Identifier: GPL-2.0-only OR BSD-2-Clause +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/mfd/spacemit,p1.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: P1 Power Management Integrated Circuit + +maintainers: + - Troy Mitchell <troymitchell988@xxxxxxxxx> + +description: + PMIC chip P1 produced by SpacemiT.
