[U-Boot] [PATCH v3 1/9] sunxi: add pinctrl (UCLASS_PINCTRL) support for sunxi

Philipp Tomsich philipp.tomsich at theobroma-systems.com
Wed Mar 1 21:20:00 UTC 2017


This change adds a full device-model pinctrl driver for sunxi (tested with
sun50iw1p1) based on the support available in Linux.

Details are:
 * implements a driver for pinctrl devices and assigns sun50i-a64-pinctrl
   and sun50i-a64-r-pinctrl to it
 * dynamically creates the driver_data for a sunxi_gpio (see sunxi_gpio.c)
   driver and binds it to the same device-tree node
 * lifts and reuses the pinctrl-sunxi.h and pinctrl-sun50i-a64.c files from
   Linux (thanks to Maxime and Andre) and adds a pinctrl-sun50i-a64-r.c (to
   be picked up for inclusion into Linux again)

+* 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: Should be one of the followings (depending on you SoC):
+  "allwinner,sun4i-a10-pinctrl"
+  "allwinner,sun5i-a10s-pinctrl"
+  "allwinner,sun5i-a13-pinctrl"
+  "allwinner,sun6i-a31-pinctrl"
+  "allwinner,sun6i-a31s-pinctrl"
+  "allwinner,sun6i-a31-r-pinctrl"
+  "allwinner,sun7i-a20-pinctrl"
+  "allwinner,sun8i-a23-pinctrl"
+  "allwinner,sun8i-a23-r-pinctrl"
+  "allwinner,sun8i-a33-pinctrl"
+  "allwinner,sun9i-a80-pinctrl"
+  "allwinner,sun9i-a80-r-pinctrl"
+  "allwinner,sun8i-a83t-pinctrl"
+  "allwinner,sun8i-h3-pinctrl"
+  "allwinner,sun8i-h3-r-pinctrl"
+  "allwinner,sun50i-a64-pinctrl"
+  "nextthing,gr8-pinctrl"
+
+- reg: Should contain the register physical address and length for the
+  pin controller.
+
+- clocks: phandle to the clocks feeding the pin controller:
+  - "apb": the gated APB parent clock
+  - "hosc": the high frequency oscillator in the system
+  - "losc": the low frequency oscillator in the system
+
+Note: For backward compatibility reasons, the hosc and losc clocks are only
+required if you need to use the optional input-debounce property. Any new
+device tree should set them.
+
+Optional properties:
+  - input-debounce: Array of debouncing periods in microseconds. One period per
+    irq bank found in the controller. 0 if no setup required.
+
+
+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.
+
+This driver supports the generic pin multiplexing and configuration
+bindings. For details on each properties, you can refer to
+./pinctrl-bindings.txt.
+
+Required sub-node properties:
+  - pins
+  - function
+
+Optional sub-node properties:
+  - bias-disable
+  - bias-pull-up
+  - bias-pull-down
+  - drive-strength
+
+*** Deprecated pin configuration and multiplexing binding
+
+Required subnode-properties:
+
+- allwinner,pins: List of strings containing the pin name.
+- allwinner,function: Function to mux the pins listed above to.
+
+Optional subnode-properties:
+- allwinner,drive: Integer. Represents the current sent to the pin
+    0: 10 mA
+    1: 20 mA
+    2: 30 mA
+    3: 40 mA
+- allwinner,pull: Integer.
+    0: No resistor
+    1: Pull-up resistor
+    2: Pull-down resistor
+
+Examples:
+
+pio: pinctrl at 01c20800 {
+	compatible = "allwinner,sun5i-a13-pinctrl";
+	reg = <0x01c20800 0x400>;
+	#address-cells = <1>;
+	#size-cells = <0>;
+
+	uart1_pins_a: uart1 at 0 {
+		allwinner,pins = "PE10", "PE11";
+		allwinner,function = "uart1";
+		allwinner,drive = <0>;
+		allwinner,pull = <0>;
+	};
+
+	uart1_pins_b: uart1 at 1 {
+		allwinner,pins = "PG3", "PG4";
+		allwinner,function = "uart1";
+		allwinner,drive = <0>;
+		allwinner,pull = <0>;
+	};
+};
+
+
+GPIO and interrupt controller
+-----------------------------
+
+This hardware also acts as a GPIO controller and an interrupt
+controller.
+
+Consumers that would want to refer to one or the other (or both)
+should provide through the usual *-gpios and interrupts properties a
+cell with 3 arguments, first the number of the bank, then the pin
+inside that bank, and finally the flags for the GPIO/interrupts.
+
+Example:
+
+xio: gpio at 38 {
+	compatible = "nxp,pcf8574a";
+	reg = <0x38>;
+
+	gpio-controller;
+	#gpio-cells = <2>;
+
+	interrupt-parent = <&pio>;
+	interrupts = <6 0 IRQ_TYPE_EDGE_FALLING>;
+	interrupt-controller;
+	#interrupt-cells = <2>;
+};
+
+reg_usb1_vbus: usb1-vbus {
+	compatible = "regulator-fixed";
+	regulator-name = "usb1-vbus";
+	regulator-min-microvolt = <5000000>;
+	regulator-max-microvolt = <5000000>;
+	gpio = <&pio 7 6 GPIO_ACTIVE_HIGH>;
+};
