The Allwinner SoCs have an IP module that handle both the muxing and the
GPIOs.
This IP has 8 banks of 32 bits, with a number of pins actually useful
for each of these banks varying from one to another, and depending on
the SoC used on the board.
This driver only implements the pinctrl part, the gpio part will come
eventually.

+* Allwinner A1X Pin Controller
+
+The pins controlled by sunXi pin controller are organized in banks,
+each bank has 32 pins. Each pin has 7 multiplexing functions, with
+the first two functions being GPIO in and out. The configuration on
+the pins includes drive strength and pull-up.
+
+Required properties:
+- compatible: "allwinner,<soc>-pinctrl". Supported SoCs for now are:
+ sun5i.
+- reg: Should contain the register physical address and length for the
+ pin controller.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices.
+
+A pinctrl node should contain at least one subnodes representing the
+pinctrl groups available on the machine. Each subnode will list the
+pins it needs, and how they should be configured, with regard to muxer
+configuration, drive strength and pullups. If one of these options is
+not set, its actual value will be unspecified.
+
+Required subnode-properties:
+
+
+- allwinner,pin-ids: An integer array. Each integer in the array
+ specify a pin with given mux function, with bank, pin and mux packed
+ as below.
+
+ [15..12] : bank number
+ [11..4] : pin number
+ [3..0] : mux selection
+
+ This integer with mux selection packed is used as an entity by both group
+ and config nodes to identify a pin. The mux selection in the integer takes
+ effects only on group node, and will get ignored by driver with config node,
+ since config node is only meant to set up pin configurations.
+
+ Valid values for these integers are listed below.
+
+- reg: Should be the index of the group nodes for same function. This property
+ is required only for group nodes, and should not be present in any config
+ nodes.
+
+Optional subnode-properties:
+- allwinner,drive: Integer.
+ 0: To be documented
+ 1: To be documented
+ 2: To be documented
+ 3: To be documented
+- allwinner,pull: Integer.
+ 0: No resistor
+ 1: Pull-up resistor
+ 2: Pull-down resistor
+
+Examples:
+
+pinctrl at 01c20800 {
+ compatible = "allwinner,sun5i-pinctrl";
+ reg = <0x01c20800 0x400>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ uart1_pins_a: uart1 at 0 {
+ reg = <0>;
+ allwinner,pin-ids = <0x40a4 0x40b4>;
+ allwinner,drive = <0>;
+ allwinner,pull = <0>;
+ };
+
+ uart1_pins_b: uart1 at 1 {
+ reg = <1>;
+ allwinner,pin-ids = <0x6034 0x6044>;
+ allwinner,drive = <0>;
+ allwinner,pull = <0>;
+ };
+};

From: Maxime Ripard @ 2012-12-10 22:08 UTC (permalink / raw)
To: linux-arm-kernel
Since the Allwinner SoCs variants don't have the same set of pins to
handle, we need to declare the pin ranges available.
