dt-bindings: gpio: Create a trivial GPIO schema
Many simple GPIO controllers without interrupt capability have the same schema other than their compatible value. Combine all these bindings into a single schema. The criteria to be included here is must use 2 cells, have no interrupt capability, have 0 or 1 "reg" entries, and have no other resources (like clocks). Note that "ngpios" is now allowed in some cases it wasn't before and constraints on it have been dropped.

- compatible: "nintendo,hollywood-gpio"
|
|
||||||
- reg: Physical base address and length of the controller's registers.
|
|
||||||
- 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:
|
|
||||||
- bit 0 specifies polarity (0 for normal, 1 for inverted).
|
|

|
|
||||||
Optional properties:
|
|
||||||
- ngpios: see Documentation/devicetree/bindings/gpio/gpio.txt
|
|
||||||
- interrupt-controller: Marks the device node as an interrupt controller.
|
|

- #interrupt-cells: Should be two.
|
|
||||||
- interrupts: Interrupt specifier for the controller's Broadway (PowerPC)
|
|
||||||
interrupt.
|

description:
|
|
||||||
The Rockchip RK3328 General Register File (GRF) outputs only the
|
|
||||||
GPIO_MUTE pin, originally for codec mute control, but it can also be used
|
|
||||||
for general purpose. It is manipulated by the GRF_SOC_CON10 register.
|
|
||||||
If needed in the future support for the HDMI pins can also be added.
|
|
||||||
The GPIO node should be declared as the child of the GRF node.
|
|
||||||
|
|
||||||
The GPIO_MUTE pin is referred to in the format
|
|
||||||
|
|
||||||
<&grf_gpio 0 GPIO_ACTIVE_LOW>
|
|
||||||
|
|
||||||
The first cell is the pin number and
|
|
||||||
the second cell is used to specify the GPIO polarity
|
|
||||||
0 = Active high
|
|
||||||
1 = Active low
