Subject: [PATCH v1 0/3]  Add IMX8 SCU GPIO support

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.
