Merge tag 'imx-drivers-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into soc/drivers

i.MX drivers update for 6.6:

- A series from NXP i.MX developers (Peng Fan, etc.) to update imx-scu
  and imx-scu-irq firmware drivers.
- Add dedicated lockdep class for nested genpd locks to fix a lockdep
  warning in imx93-blk-ctrl driver.
- A change from Rob to explicitly include correct DT headers for i.MX
  SoC drivers.
- Use devm_platform_ioremap_resource() in imx-weim bus driver.
