To accommodate these differences, a SoC-specific 'renesas,sdhi-r9a09g057' compatible string is added. A 'vqmmc-regulator' object is introduced to handle the power enable (PWEN) and voltage level switching for the SD/MMC. Signed-off-by: Lad Prabhakar --- v3->v4 - Dropped 'renesas,sdhi-use-internal-regulator' property - Moved 'vqmmc-regulator' to the top level v2->v3 - Renamed vqmmc-r9a09g057-regulator object to vqmmc-regulator - Added regulator-compatible property for vqmmc-regulator - Added 'renesas,sdhi-use-internal-regulator' property v1->v2 - Moved vqmmc object in the if block - Updated commit message --- .../devicetree/bindings/mmc/renesas,sdhi.yaml | 26 ++++++++++++++++++- 1 file changed, 25 insertions(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/mmc/renesas,sdhi.yaml b/Documentation/devicetree/bindings/mmc/renesas,sdhi.yaml index 3d0e61e59856..d632b67080bd 100644 --- a/Documentation/devicetree/bindings/mmc/renesas,sdhi.yaml +++ b/Documentation/devicetree/bindings/mmc/renesas,sdhi.yaml @@ -18,6 +18,7 @@ properties: - renesas,sdhi-r7s9210 # SH-Mobile AG5 - renesas,sdhi-r8a73a4 # R-Mobile APE6 - renesas,sdhi-r8a7740 # R-Mobile A1 + - renesas,sdhi-r9a09g057 # RZ/V2H(P) - renesas,sdhi-sh73a0 # R-Mobile APE6 - items: - enum: @@ -111,6 +112,15 @@ properties: max-frequency: true + vqmmc-regulator: + type: object + description: VQMMC SD regulator + $ref: /schemas/regulator/regulator.yaml# + unevaluatedProperties: false + properties: + regulator-compatible: + pattern: "^vqmmc-r9a09g057-regulator" + allOf: - $ref: mmc-controller.yaml @@ -118,7 +128,9 @@ allOf: properties: compatible: contains: - const: renesas,rzg2l-sdhi + enum: + - renesas,sdhi-r9a09g057 + - renesas,rzg2l-sdhi then: properties: clocks: @@ -204,6 +216,18 @@ allOf: sectioned off to be run by a separate second clock source to allow the main core clock to be turned off to save power. + - if: + properties: + compatible: + contains: + const: renesas,sdhi-r9a09g057 + then: + required: + - vqmmc-regulator + else: + properties: + vqmmc-regulator: false + required: - compatible - reg
