+ - gpio-controller:	Marks the device node as a GPIO controller.
+ - #gpio-cells: 	Should be two. For consumer use see gpio.txt.
+
+Optional properties:
+ - #daisy-chained-devices:
+			Number of chips in the daisy-chain (default is 1).
+ - maxim,modesel-gpios: GPIO pins to configure modesel of each chip.
+			The number of GPIOs must equal "#daisy-chained-devices"
+			(if each chip is driven by a separate pin) or 1
+			(if all chips are wired to the same pin).
+ - maxim,fault-gpios: 	GPIO pins to read fault of each chip.
+			The number of GPIOs must equal "#daisy-chained-devices"
+			or 1.
+ - maxim,db0-gpios:	GPIO pins to configure debounce of each chip.
+			The number of GPIOs must equal "#daisy-chained-devices"
+			or 1.
+ - maxim,db1-gpios:	GPIO pins to configure debounce of each chip.
+			The number of GPIOs must equal "maxim,db0-gpios".
+ - maxim,modesel-8bit:	Boolean whether the modesel pin of the chips is
+			pulled high (8-bit mode).  Use this if the modesel pin
+			is hardwired and consequently "maxim,modesel-gpios"
+			cannot be specified.  By default if neither this nor
+			"maxim,modesel-gpios" is given, the driver assumes
+			that modesel is pulled low (16-bit mode).
+ - maxim,ignore-undervoltage:
+			Boolean whether to ignore undervoltage alarms signaled
+			by the "maxim,fault-gpios" or by the status byte
+			(in 16-bit mode).  Use this if the chips are powered
+			through 5VOUT instead of VCC24V, in which case they
+			will constantly signal undervoltage.

-Microchip MCP2308/MCP23S08/MCP23017/MCP23S17 driver for
-8-/16-bit I/O expander with serial interface (I2C/SPI)
-
-Required properties:
-- compatible : Should be
-    - "mcp,mcp23s08" (DEPRECATED) for  8 GPIO SPI version
-    - "mcp,mcp23s17" (DEPRECATED) for 16 GPIO SPI version
-    - "mcp,mcp23008" (DEPRECATED) for  8 GPIO I2C version or
-    - "mcp,mcp23017" (DEPRECATED) for 16 GPIO I2C version of the chip
-
-    - "microchip,mcp23s08" for  8 GPIO SPI version
-    - "microchip,mcp23s17" for 16 GPIO SPI version
-    - "microchip,mcp23s18" for 16 GPIO SPI version
-    - "microchip,mcp23008" for  8 GPIO I2C version or
-    - "microchip,mcp23017" for 16 GPIO I2C version of the chip
-    NOTE: Do not use the old mcp prefix any more. It is deprecated and will be
-    removed.
-- #gpio-cells : Should be two.
-  - first cell is the pin number
-  - second cell is used to specify flags. Flags are currently unused.
-- gpio-controller : Marks the device node as a GPIO controller.
-- reg : For an address on its bus. I2C uses this a the I2C address of the chip.
-        SPI uses this to specify the chipselect line which the chip is
-        connected to. The driver and the SPI variant of the chip support
-        multiple chips on the same chipselect. Have a look at
-        microchip,spi-present-mask below.
-
-Required device specific properties (only for SPI chips):
-- mcp,spi-present-mask (DEPRECATED)
-- microchip,spi-present-mask : This is a present flag, that makes only sense for SPI
-        chips - as the name suggests. Multiple SPI chips can share the same
-        SPI chipselect. Set a bit in bit0-7 in this mask to 1 if there is a
-        chip connected with the corresponding spi address set. For example if
-        you have a chip with address 3 connected, you have to set bit3 to 1,
-        which is 0x08. mcp23s08 chip variant only supports bits 0-3. It is not
-        possible to mix mcp23s08 and mcp23s17 on the same chipselect. Set at
-        least one bit to 1 for SPI chips.
-    NOTE: Do not use the old mcp prefix any more. It is deprecated and will be
-    removed.
-- spi-max-frequency = The maximum frequency this chip is able to handle
-
-Optional properties:
-- #interrupt-cells : Should be two.
-  - first cell is the pin number
-  - second cell is used to specify flags.
-- interrupt-controller: Marks the device node as a interrupt controller.
-
-Optional device specific properties:
-- microchip,irq-mirror: Sets the mirror flag in the IOCON register. Devices
-        with two interrupt outputs (these are the devices ending with 17 and
-        those that have 16 IOs) have two IO banks: IO 0-7 form bank 1 and
-        IO 8-15 are bank 2. These chips have two different interrupt outputs:
-        One for bank 1 and another for bank 2. If irq-mirror is set, both
-        interrupts are generated regardless of the bank that an input change
-        occurred on. If it is not set, the interrupt are only generated for the
-        bank they belong to.
-        On devices with only one interrupt output this property is useless.
-- microchip,irq-active-high: Sets the INTPOL flag in the IOCON register. This
-        configures the IRQ output polarity as active high.
-
-Example I2C (with interrupt):
-gpiom1: gpio@20 {
-        compatible = "microchip,mcp23017";
-        gpio-controller;
-        #gpio-cells = <2>;
-        reg = <0x20>;
-
-        interrupt-parent = <&gpio1>;
-        interrupts = <17 IRQ_TYPE_LEVEL_LOW>;
-        interrupt-controller;
-        #interrupt-cells=<2>;
-        microchip,irq-mirror;
-};
-
-Example SPI:
-gpiom1: gpio@0 {
-        compatible = "microchip,mcp23s17";
-        gpio-controller;
-        #gpio-cells = <2>;
-        spi-present-mask = <0x01>;
-        reg = <0>;
-        spi-max-frequency = <1000000>;

+UniPhier GPIO controller

+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells: Should be 2.  The first cell is the pin number and the second
+  cell is used to specify optional parameters.
+- interrupt-parent: Specifies the parent interrupt controller.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Should be 2.  The first cell defines the interrupt number.
+  The second cell bits[3:0] is used to specify trigger type as follows:
+    1 = low-to-high edge triggered
+    2 = high-to-low edge triggered
+    4 = active high level-sensitive
+    8 = active low level-sensitive
+  Valid combinations are 1, 2, 3, 4, 8.
+- ngpios: Specifies the number of GPIO lines.
+- gpio-ranges: Mapping to pin controller pins (as described in gpio.txt)
+- socionext,interrupt-ranges: Specifies an interrupt number mapping between
+  this GPIO controller and its interrupt parent, in the form of arbitrary
+  number of <child-interrupt-base parent-interrupt-base length> triplets.
+
+Optional properties:
+- gpio-ranges-group-names: Used for named gpio ranges (as described in gpio.txt)
+
+Example:
+	gpio: gpio@55000000 {

+Consumer Example:
+
+	sdhci0_pwrseq {
+		compatible = "mmc-pwrseq-emmc";
+		reset-gpios = <&gpio UNIPHIER_GPIO_PORT(29, 4) GPIO_ACTIVE_LOW>;
+	};
+
+Please note UNIPHIER_GPIO_PORT(29, 4) represents PORT294 in the SoC document.
+Unfortunately, only the one's place is octal in the port numbering.  (That is,
+PORT 8, 9, 18, 19, 28, 29, ... are missing.)  UNIPHIER_GPIO_PORT() is a helper
