-Broadcom Kona Family GPIO
-=========================
-
-This GPIO driver is used in the following Broadcom SoCs:
- BCM11130, BCM11140, BCM11351, BCM28145, BCM28155
-
-The Broadcom GPIO Controller IP can be configured prior to synthesis to
-support up to 8 banks of 32 GPIOs where each bank has its own IRQ. The
-GPIO controller only supports edge, not level, triggering of interrupts.
-
-Required properties
--------------------
-
-- compatible: "brcm,bcm11351-gpio", "brcm,kona-gpio"
-- reg: Physical base address and length of the controller's registers.
-- interrupts: The interrupt outputs from the controller. There is one GPIO
- interrupt per GPIO bank. The number of interrupts listed depends on the
- number of GPIO banks on the SoC. The interrupts must be ordered by bank,
- starting with bank 0. There is always a 1:1 mapping between banks and
- IRQs.
-- #gpio-cells: Should be <2>. The first cell is the pin number, the second
- cell is used to specify optional parameters:
- - bit 0 specifies polarity (0 for normal, 1 for inverted)
- See also "gpio-specifier" in .../devicetree/bindings/gpio/gpio.txt.
-- #interrupt-cells: Should be <2>. The first cell is the GPIO number. The
- second cell is used to specify flags. The following subset of flags is
- supported:
- - trigger type (bits[1:0]):
- 1 = low-to-high edge triggered.
- 2 = high-to-low edge triggered.
- 3 = low-to-high or high-to-low edge triggered
- Valid values are 1, 2, 3
- See also .../devicetree/bindings/interrupt-controller/interrupts.txt.
-- gpio-controller: Marks the device node as a GPIO controller.
-- interrupt-controller: Marks the device node as an interrupt controller.

-Example:
- gpio: gpio@35003000 {
- compatible = "brcm,bcm11351-gpio", "brcm,kona-gpio";
- reg = <0x35003000 0x800>;
- interrupts =
- <GIC_SPI 106 IRQ_TYPE_LEVEL_HIGH
- GIC_SPI 115 IRQ_TYPE_LEVEL_HIGH
- GIC_SPI 114 IRQ_TYPE_LEVEL_HIGH
- GIC_SPI 113 IRQ_TYPE_LEVEL_HIGH
- GIC_SPI 112 IRQ_TYPE_LEVEL_HIGH
- GIC_SPI 111 IRQ_TYPE_LEVEL_HIGH>;
- #gpio-cells = <2>;
- #interrupt-cells = <2>;

BROADCOM MPI3 STORAGE CONTROLLER DRIVER
Convert Broadcom Kona family GPIO controller bindings to DT schema. Changes during conversion: - add used, but previously undocumented SoC-specific compatibles Signed-off-by: Stanislav Jakubek <stano.jakubek@gmail.com> --- RFC since dt_binding_check is giving me these errors/warnings: Documentation/devicetree/bindings/gpio/brcm,kona-gpio.example.dts:21.23-34.11: Warning (interrupts_property): /example-0/gpio@35003000: Missing interrupt-parent The old txt bindings and all current DTs do not use interrupt-parent AFAICT, so I'm not sure what to do about that.
