Add RGPIO gpio driver. This driver is used for i.MX93 and i.MX8ULP. GPIO pinctrl, read/write and interrupt is supported. Runtime mmio configuration is enabled, so no need for region definition in mimx9/mmu_region.c Signed-off-by: Chekhov Ma <chekhov.ma@nxp.com>

IMX pin selection peripheral does not follow specific
|
|
pattern for which GPIO port uses which pinmux. Use this property to specify
|
|
pinctrl nodes to use for the gpio port when CONFIG_PINCTRL=y. Note that
|
|
the order of the nodes matters. The first node for gpio1 will be used
|
|
as the pinmux for gpio0, port 0.
