Merge tag 'imx-drivers-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/shawngu...

i.MX drivers update for 4.20:
 - A couple of patches from Anson to update variable and macro naming
   in GPCv2 driver, as a preparation of reusing the driver on i.MX8.
 - Switch GPC/GPCv2 drivers to use SPDX identifier for licence claiming.
 - Clean up the unnecessary DT node name NULL pointer checking from
   imx-weim driver, since it can never be NULL at all.
 - A couple of improvements on GPC driver from Sven Schmitt to correct
   PDN register and use GPC_PGC_DOMAIN_* indexes for consistency.
