From: Conor Dooley <[e-mail]>

This patchset adds support for the Microchip PolarFire clkcfg
hardware block.

Changes since v5:
* Dropped clock-output-names property

Major changes since v4:
* Adjusted license for microchip,mpfs-clock.h to match microchip,mpfs.yaml
* Corrected the number of clocks to 33 from 32

Major changes since v3:
* Patch reformatted so microchip,mpfs-clock.h is part of device-tree patch

Major changes since v2:
* In mpfs_cfg_clk_set_rate, return immediately if divider_get_val
    returns <0 
* rebased to v5.12-rc1

Major changes since v1:
 * Dependency on SOC_MICROCHIP_POLARFIRE
 * All references to PFSOC/pfsoc changed to MPFS/mpfs
 * Cleaned error handling in _probe
 * Re-ordered code to place structs et al at top
