The system controller (SCU) is the central unit to manage the resources
on i.MX8 platforms. The SCU firmware provides a set of APIs to access
the GPIO PINs on the SCU domain.
This patch series implements the standard GPIO driver over the SCU
firmware APIs, so that the GPIOs on the SCU domain could be accessed
like a local GPIO PINs.
Changes in V5:
- rename the file name from fsl,imx-sc-gpio to fsl,imx8qxp-sc-gpio
to match the compatible string
Changes in V4:
- remove the generic compatible of "fsl,imx-sc-gpio"
- update the gpio $ref in "fsl,scu.yaml" as the file name is changed
- update the commit comment for 0003 because the driver is moved to the
directory of "drivers/gpio"
Changes in V3:
- follow the other imx8 SCU binding rule and rename the compatible string
from fsl,imx8-scu-gpio to fsl,imx8qxp-sc-gpio
- rename the doc file from fsl,imx8-scu-gpio.yaml to fsl,imx-sc-gpio.yaml
Changes in V2:
- move the driver into the gpio directory per Krzysztof's feedback
- change the subnode description in file fsl,scu.yaml
- fix the dt_binding_check error

v5 looks good to me!

Applied the series, thanks!
