contains information structures as follows:
gpio-range-list ::= <single-gpio-range> [gpio-range-list]
- single-gpio-range ::=
+ single-gpio-range ::= <numeric-gpio-range> | <named-gpio-range>
+ numeric-gpio-range ::=
<pinctrl-phandle> <gpio-base> <pinctrl-base> <count>
+ named-gpio-range ::= <pinctrl-phandle> <gpio-base> '<0 0>'
gpio-phandle : phandle to pin controller node.
gpio-base : Base GPIO ID in the GPIO controller
pinctrl-base : Base pinctrl pin ID in the pin controller
The "pin controller node" mentioned above must conform to the bindings
described in ../pinctrl/pinctrl-bindings.txt.
+In case named gpio ranges are used (ranges with both <pinctrl-base> and
+<count> set to 0), the property gpio-ranges-group-names contains one string
+for every single-gpio-range in gpio-ranges:
+ gpiorange-names-list ::= <gpiorange-name> [gpiorange-names-list]
+ gpiorange-name : Name of the pingroup associated to the GPIO range in
+ the respective pin controller.
+
+Elements of gpiorange-names-list corresponding to numeric ranges contain
+the empty string. Elements of gpiorange-names-list corresponding to named
+ranges contain the name of a pin group defined in the respective pin
+controller. The number of pins/GPIOs in the range is the number of pins in
+that pin group.
+
Previous versions of this binding required all pin controller nodes that
were referenced by any gpio-ranges property to contain a property named
#gpio-range-cells with value <3>. This requirement is now deprecated.
compatibility reasons, and would still be required even in new device
trees that need to be compatible with older software.
-Example:
+Example 1:
qe_pio_e: gpio-controller@1460 {
#gpio-cells = <2>;
Here, a single GPIO controller has GPIOs 0..9 routed to pin controller
pinctrl1's pins 20..29, and GPIOs 10..19 routed to pin controller pinctrl2's
pins 50..59.
+
+Example 2:
+
+ gpio_pio_i: gpio-controller@14B0 {
+ #gpio-cells = <2>;
+ compatible = "fsl,qe-pario-bank-e", "fsl,qe-pario-bank";
+ reg = <0x1480 0x18>;
+ gpio-controller;
+ gpio-ranges = <&pinctrl1 0 20 10>,
+ <&pinctrl2 10 0 0>,
+ <&pinctrl1 15 0 10>,
+ <&pinctrl2 25 0 0>;
+ gpio-ranges-group-names = "",
+ "foo",
+ "",
+ "bar";
+ };
+
+Here, three GPIO ranges are defined wrt. two pin controllers. pinctrl1 GPIO
+ranges are defined using pin numbers whereas the GPIO ranges wrt. pinctrl2
+are named "foo" and "bar".

+Abilis Systems TB10x pin controller
+===================================
+
+Required properties
+-------------------
+
+- compatible: should be "abilis,tb10x-iomux";
+- reg: should contain the physical address and size of the pin controller's
+ register range.
+
+
+Function definitions
+--------------------
+
+Functions are defined (and referenced) by sub-nodes of the pin controller.
+Every sub-node defines exactly one function (implying a set of pins).
+Every function is associated to one named pin group inside the pin controller
+driver and these names are used to associate pin group predefinitions to pin
+controller sub-nodes.
+
+Required function definition subnode properties:
+ - abilis,function: should be set to the name of the function's pin group.
+
+The following pin groups are available:
+ - GPIO ports: gpioa, gpiob, gpioc, gpiod, gpioe, gpiof, gpiog,
+ gpioh, gpioi, gpioj, gpiok, gpiol, gpiom, gpion
+ - Serial TS input ports: mis0, mis1, mis2, mis3, mis4, mis5, mis6, mis7
+ - Parallel TS input ports: mip1, mip3, mip5, mip7
+ - Serial TS output ports: mos0, mos1, mos2, mos3
+ - Parallel TS output port: mop
+ - CI+ port: ciplus
+ - CableCard (Mcard) port: mcard
+ - Smart card ports: stc0, stc1
+ - UART ports: uart0, uart1
+ - SPI ports: spi1, spi3
+ - JTAG: jtag
+
+All other ports of the chip are not multiplexed and thus not managed by this
+driver.
+
+
+GPIO ranges definition
+----------------------
+
+The named pin groups of GPIO ports can be used to define GPIO ranges as
+explained in Documentation/devicetree/bindings/gpio/gpio.txt.
+
+
+Example
+-------
+
+iomux: iomux@FF10601c {
+ compatible = "abilis,tb10x-iomux";
+ reg = <0xFF10601c 0x4>;
+ pctl_gpio_a: pctl-gpio-a {

+ };
+ pctl_uart0: pctl-uart0 {

+ };
+};
+uart@FF100000 {
+ compatible = "snps,dw-apb-uart";
+ reg = <0xFF100000 0x100>;
+ clock-frequency = <166666666>;
+ interrupts = <25 1>;
+ reg-shift = <2>;

such as pull-up, multi drive, etc.
Required properties for iomux controller:
-- compatible: "atmel,at91rm9200-pinctrl"
+- compatible: "atmel,at91rm9200-pinctrl" or "atmel,at91sam9x5-pinctrl"
- atmel,mux-mask: array of mask (periph per bank) to describe if a pin can be
configured in this periph mode. All the periph and bank need to be describe.
Please refer to each fsl,<soc>-pinctrl.txt binding doc for supported SoCs.
Required properties for pin configuration node:
-- fsl,pins: two integers array, represents a group of pins mux and config
- setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a
- pin working on a specific function, which consists of a tuple of
- <mux_reg conf_reg input_reg mux_val input_val>. CONFIG is the pad setting
- value like pull-up on this pin.
+- fsl,pins: each entry consists of 6 integers and represents the mux and config
+ setting for one pin. The first 5 integers <mux_reg conf_reg input_reg mux_val
+ input_val> are specified using a PIN_FUNC_ID macro, which can be found in
+ imx*-pinfunc.h under device tree source folder. The last integer CONFIG is
+ the pad setting value like pull-up on this pin. And that's why fsl,pins entry
+ looks like <PIN_FUNC_ID CONFIG> in the example below.
Bits used for CONFIG:
NO_PAD_CTL(1 << 31): indicate this pin does not need config.

+According to the BF54x HRM, pint means "pin interrupt".
+http://www.analog.com/static/imported-files/processor_manuals/ADSP-BF54x_hwr_rev1.2.pdf
+
+ADSP-BF54x processor Blackfin processors have four SIC interrupt chan-
+nels dedicated to pin interrupt purposes. These channels are managed by
+four hardware blocks, called PINT0, PINT1, PINT2, and PINT3. Every PINTx
+block can sense to up to 32 pins. While PINT0 and PINT1 can sense the
+pins of port A and port B, PINT2 and PINT3 manage all the pins from port
+C to port J as shown in Figure 9-2.
+
+n BF54x HRM:
+The ten GPIO ports are subdivided into 8-bit half ports, resulting in lower and
+upper half 8-bit units. The PINTx_ASSIGN registers control the 8-bit multi-
+plexers shown in Figure 9-3. Lower half units of eight pins can be
+forwarded to either byte 0 or byte 2 of either associated PINTx block.
+Upper half units can be forwarded to either byte 1 or byte 3 of the pin
+interrupt blocks, without further restrictions.
+
+All MMR registers in the pin interrupt module are 32 bits wide. To simply the
+mapping logic, this driver only maps a 16-bit gpio port to the upper or lower
+16 bits of a PINTx block. You can find the Figure 9-3 on page 583.
+
+Each IRQ domain is binding to a GPIO bank device. 2 GPIO bank devices can map
+to one PINT device. Two in "struct gpio_pint" are used to ease the PINT
+interrupt handler.
+
+The GPIO bank mapping to the lower 16 bits of the PINT device set its IRQ
+domain pointer in domain[0]. The IRQ domain pointer of the other bank is set
+to domain[1]. PINT interrupt handler adi_gpio_handle_pint_irq() finds out
+the current domain pointer according to whether the interrupt request mask
+is in lower 16 bits (domain[0]) or upper 16bits (domain[1]).
+
+A PINT device is not part of a GPIO port device in Blackfin. Multiple GPIO
+port devices can be mapped to the same PINT device.
