+title: Simple MMC power sequence provider binding
+
+maintainers:
+  - Ulf Hansson <ulf.hansson@linaro.org>
+
+description:
+  The purpose of the simple MMC power sequence provider is to supports a set
+  of common properties between various SOC designs. It thus enables us to use
+  the same provider for several SOC designs.
+
+properties:
+  compatible:
+    const: mmc-pwrseq-simple
+
+  reset-gpios:
+    minItems: 1
+    # Put some limit to avoid false warnings
+    maxItems: 32
+    description:
+      contains a list of GPIO specifiers. The reset GPIOs are asserted
+      at initialization and prior we start the power up procedure of the card.
+      They will be de-asserted right after the power has been provided to the
+      card.
+
+  clocks:
+    minItems: 1
+    description: Handle for the entry in clock-names.
+
+  clock-names:
+    items:
+      - const: ext_clock
+    description: External clock provided to the card.
+
+  post-power-on-delay-ms:
+    description:
+      Delay in ms after powering the card and de-asserting the
+      reset-gpios (if any).
+    $ref: /schemas/types.yaml#/definitions/uint32
+
+  power-off-delay-us:
+    description:
+      Delay in us after asserting the reset-gpios (if any)
+      during power off of the card.
