The purpose of this series is to add clock support for SAMA7G5. Along with this, clock drivers were switched to CCF and aligned with their corresponding versions present in Linux. Some changes were done for CCF, patches 1, 3, 4, 5 (I don't know if they were as is by intention of a fixes tag is needed in there).
Also patch 3/21 has been added to support clock re-reparenting (this is minimal support and hope it doesn't break anything if used).
Thank you, Claudiu Beznea
Changes in v3: - collected remaining Reviewed-by tags - rebase on top of latest master branch: e5df264e7aac ("Merge https://gitlab.denx.de/u-boot/custodians/u-boot-marvell") to adapt patch 8/21 at changes from commit 702e57e113d8 ("treewide: convert devfdt_get_addr_ptr() to dev_read_addr_ptr()")
Changes in v2: - use assert() in patch 1/21 - drop patch 2/22 from previous series - add sandbox tests for clock reparenting, device reparenting and critical clocks - adapt review comments - collected Reviewed-by tags
