Merge tag 'imx-soc-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo...

i.MX SoC update for 4.19:
 - A series from Anson Huang to add power management for i.MX6SLL,
   including standby and mem mode suspend, cpuidle support, and bus
   clock auto gating function, etc.
 - A couple of fix-ups on i.MX6SLL cpuidle random build issues.
 - A couple of cleanups on stale EPIT timer initialization and RNGA
   platform device registration function.
 - Configure i.MX51 SoC M4IF to avoid visual artifacts during video
   playback.
 - Set up i.MX51 and i.MX53 DBGEN bit of ARM_GPC register, so that
   clocks within the debug system can be activated.
 - Add a Cortex-M4 platform support which will be useful for running
   a Linux instance on Cortex-M4 core integrated in i.MX7D SoC.
 - Flag of_iomap failure in imx_aips_allow_unprivileged_access()
   function by giving a warning in there.
