GPIOLIB_IRQCHIP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The current code doesn't check if GPIOLIB_IRQCHIP is enabled, which results in
a compilation error when trying to build gpio-regmap if CONFIG_GPIOLIB_IRQCHIP
isn't enabled.
Fixes: 6a45b0e2589f ("gpiolib: Introduce gpiochip_irqchip_add_domain()")

-Bindings for the Broadcom's brcm,bcm6345-gpio memory-mapped GPIO controllers.
-
-These bindings can be used on any BCM63xx SoC. However, BCM6338 and BCM6345
-are the only ones which don't need a pinctrl driver.
-BCM6338 have 8-bit data and dirout registers, where GPIO state can be read
-and/or written, and the direction changed from input to output.
-BCM6345 have 16-bit data and dirout registers, where GPIO state can be read
-and/or written, and the direction changed from input to output.
-
-Required properties:
- - compatible: should be "brcm,bcm6345-gpio"
- - reg-names: must contain
- "dat" - data register
- "dirout" - direction (output) register
- - reg: address + size pairs describing the GPIO register sets;
- order must correspond with the order of entries in reg-names
- - #gpio-cells: must be set to 2. The first cell is the pin number and
- the second cell is used to specify the gpio polarity:
- 0 = active high
- 1 = active low
- - gpio-controller: Marks the device node as a gpio controller.
-
-Optional properties:
- - native-endian: use native endian memory.
-
-Examples:
- - BCM6338:
- gpio: gpio-controller@fffe0407 {
- compatible = "brcm,bcm6345-gpio";
- reg-names = "dirout", "dat";
- reg = <0xfffe0407 1>, <0xfffe040f 1>;
-
- #gpio-cells = <2>;
- gpio-controller;
- };
-
- - BCM6345:
- gpio: gpio-controller@fffe0406 {
- compatible = "brcm,bcm6345-gpio";
- reg-names = "dirout", "dat";
- reg = <0xfffe0406 2>, <0xfffe040a 2>;
- native-endian;

Add a pincontrol driver for BCM6328. BCM6328 supports muxing 32 pins as
GPIOs, as LEDs for the integrated LED controller, or various other
functions. Its pincontrol mux registers also control other aspects, like
switching the second USB port between host and device mode.
