V3:
 Add R-b/T-b tag from Frieder
 For Patch 8, add the explaination in yaml file per Rob and Frieder

V2:
 - Add R-b/A-b tag
 - Merge V1 patch 13 to V2 patch 6
 - Drop V1 patch 15
 - Merge V1 patch 16 to V2 patch 5 and add comments in patch 5 to explain
 details
 - Add explaination in patch 8 for "why the resets are not defined"

This patchset is a pick up Lucas's gpcv2 work for i.MX8MM and several
minor changes from me to make it could work with i.MX BLK-CTL driver.

Thanks for Lucas's work and suggestion, Frieder Schrempf for collecting
all the patches, Jacky Bai on help debug issues.
