Hi Olof, Hi Arnd,

This pull request is based on renesas-pinmux-for-v3.11 which you have previously pulled. It provides the GPIO R-Car driver. I have broken this pull-request out from a separate pull request I plan to send with further pinmux updates as it relates specifically to DT. And I wanted to give you the option of merging it separately.

The following changes since commit 5fcf4a3c3a5bc08bf72a50ef1332501a3c1b96bb:

ARM: shmobile: marzen: Use RCAR_GP_PIN macro (2013-06-05 17:18:24 +0900)

cover gpio-rcar: Add DT support

From: Laurent Pinchart <[email protected]>

Add DT bindings for the gpio-rcar driver and read the device configuration from the DT node at probe time if available.

+* Renesas R-Car GPIO Controller
+
+Required Properties:
+
+  - compatible: should be one of the following.
+    - "renesas,gpio-r8a7778": for R8A7778 (R-Mobile M1) compatible GPIO controller.
+    - "renesas,gpio-r8a7779": for R8A7779 (R-Car H1) compatible GPIO controller.
+    - "renesas,gpio-r8a7790": for R8A7790 (R-Car H2) compatible GPIO controller.
+    - "renesas,gpio-rcar": for generic R-Car GPIO controller.
+
+  - reg: Base address and length of each memory resource used by the GPIO
+    controller hardware module.
+
+  - interrupt-parent: phandle of the parent interrupt controller.
+  - interrupts: Interrupt specifier for the controllers interrupt.
+
+  - gpio-controller: Marks the device node as a gpio controller.
+  - #gpio-cells: Should be 2. The first cell is the GPIO number and the second
+    cell is used to specify optional parameters as bit flags. Only the GPIO
+    active low flag (bit 0) is currently supported.
+  - gpio-ranges: Range of pins managed by the GPIO controller as a 4-cells
+    tuple using the following syntax.
+
+    <[phandle of the pin controller node]
+     0
+     [index of the first pin]
+     [number of pins]>
+
+Please refer to gpio.txt in this directory for details of the common GPIO
+bindings used by client devices.
+
+Example: R8A7779 (R-Car H1) GPIO controller nodes
+
+	gpio0: gpio at ffc40000 {
+		compatible = "renesas,gpio-r8a7779", "renesas,gpio-rcar";
+		reg = <0xffc40000 0x2c>;
+		interrupt-parent = <&gic>;
+		interrupts = <0 141 0x4>;
+		#gpio-cells = <2>;
+		gpio-controller;
+		gpio-ranges = <&pfc 0 0 32>;
+	};
+	...
+	gpio6: gpio at ffc46000 {
+		compatible = "renesas,gpio-r8a7779", "renesas,gpio-rcar";
+		reg = <0xffc46000 0x2c>;
+		interrupt-parent = <&gic>;
+		interrupts = <0 147 0x4>;
+		#gpio-cells = <2>;
+		gpio-controller;
+		gpio-ranges = <&pfc 0 192 9>;

Hi,

I don't see this cc/acked by Linus or Grant/Rob. However, the binding looks very vanilla to me, so I'll merge it anyway.

Hi,
I don't see this cc/acked by Linus or Grant/Rob.

The patch has been acked by Linus, but it seems the ack got lost somewhere.
