2023-10-05pmdomain: imx: Move Kconfig options to the pmdomain subsystemUlf Hansson1-19/+0
The Kconfig options belongs closer to the corresponding implementations, hence let's move them from the soc- and firmware subsystem to the pmdomain subsystem.

Currently the dependencies of the blk-ctrl drivers are not fully described in Kconfig, which can trip over the compile tests on platforms where those drivers are not usually enabled.

2020-07-13firmware: imx: Move i.MX SCU soc driver into imx firmware folderAnson Huang1-9/+0
The i.MX SCU soc driver depends on SCU firmware driver, so it has to use platform driver model for proper defer probe operation, since it has no device binding in DT file, a simple platform device is created together inside the platform driver. To make it more clean, we can just move the entire SCU soc driver into imx firmware folder and initialized by i.MX SCU firmware driver.

Add i.MX SCU SoC info driver to support i.MX8QXP SoC, introduce driver dependency into Kconfig as CONFIG_IMX_SCU must be selected to support i.MX SCU SoC driver, also need to use platform driver model to make sure IMX_SCU driver is probed before i.MX SCU SoC driver.
