[v3,00/15] soc: xilinx: vcu: Convert driver to clock provider

Message

Hello,

This is v3 of the series to transform the xlnx_vcu driver into a proper clock
provider driver. The driver implements a clock provider of a PLL and four
output clocks created from the PLL via dividers that are used by the Xilinx
Video Codec Unit.

Compared to v2, I added a missing kernel-doc, collected Acked-By: tags, and
rebased it on clk-next.

Michael

Changelog:

v3:
- Add missing kernel-doc

v2:
- Remove dummy clock and explicit re-parenting of mux clocks
- Add patches to fix checkpatch warnings
- Move driver from drivers/soc to drivers/clk
- Use clk_parent_data instead of parent_names
- Add missing decoder clocks
- Fix smatch warnings
- Fix kernel-doc
