v5 -> v6:
- Removed "_clk" in clock-names.
- Added Reviewed-by.

v4 -> v5:
- In v4 dt-bindings, missed adding "clock-names" in required
properties and example. So, added them.

v3 -> v4:
- Updated "clocks" description.
- Added "clock-names".

v2 -> v3:
- Fixed dt_binding_check errors.

v1 -> v2:
- Updated example provided for clk controller DT node.

+description: |
+ The LAN966X Generic clock controller contains 3 PLLs - cpu_clk,
+ ddr_clk and sys_clk. This clock controller generates and supplies
+ clock to various peripherals within the SoC.
