From: Chunyan Zhang <[e-mail]>

Add SC9863A specific clock driver and devicetree bindings for it,
this patch add to support the new way of specifying parents
without name strings of clocks.

Also this patchset added support gate clock for pll which need to
wait a certain time for stable after being switched on.

Changes from v4:
* Fixed dt_binding_check warnings.

Changes from v3:
* Rebased onto v5.6-rc1.

Changes from v2:
* Addressed comments from Stephen:
- Remove ununsed header file from sc9863a-clk.c;
- Added comments for clocks which were marked with CLK_IGNORE_UNUSED,
  and removed some unnecessary CLK_IGNORE_UNUSED;
- Added error checking for sprd_clk_regmap_init().

* Addressed comments from Rob:
- Put some clocks under syscon nodes, since these clocks have the same
  physical address base with the syscon;
- Added clocks maxItems and listed out clock-names.

* Added Rob's reviewed-by on patch 4.

Changes from v1:
* Addressed comments:
- Removed redefine things;
- Switched DT bindings to yaml schema;
- Added macros for the new way of specifying clk parents; 
- Switched to use the new way of specifying clk parents;
- Clean CLK_IGNORE_UNUSED flags for some SC9863A clocks;
- Dropped the module alias;
- Use device_get_match_data() instead of of_match_node();

* Added Rob's Acked-by on patch 2.
