[PATCH v3 00/21] clk: at91: add sama7g5 support

[Claudiu Beznea]

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
