[PATCH v4 0/5] Add Microchip PolarFire Soc Support

This series adds minimal support for Microchip Polar Fire Soc Icicle kit.
It is rebased on v5.12-rc1 and depends on clock support.
Only MMC and ethernet drivers are enabled via this series.
The idea here is to add the foundational patches so that other drivers
can be added to on top of this. The device tree may change based on
feedback on bindings of individual driver support patches.

This series has been tested on Qemu and Polar Fire Soc Icicle kit.
It depends on the updated clock-series[2] and macb fix[3].
The series is also tested by Lewis from Microchip.

The series can also be found at.

Changes from v3->v4:
1. Fixed few DT specific issues.
2. Rebased on top of new clock driver.
3. SD card functionality is verified.

Changes from v2->v3:
1. Fixed a typo in dt binding.
2. Included MAINTAINERS entry for PolarFire SoC.
3. Improved the dts file by using lowercase clock names and keeping phy
details in board specific dts file.

Changes from v1->v2:
1. Modified the DT to match the device tree in U-Boot.
2. Added both eMMC & SDcard entries in DT. However, SD card is only enabled
as it allows larger storage option for linux distros.
