[PATCH v3 0/3] pic64gx clk kconfig/binding changes

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

Mostly this is stuff that PH did last year, but rebased on top of
current work, now that the clock driver rework patches have been
applied.

v3: rebase on linus' tree

v2: fix the binding, d'oh

[PATCH v3 1/3] clk: microchip: drop POLARFIRE from ARCH_MICROCHIP_POLARFIRE

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

This driver is used by non-polarfire devices now, and the ARCH_MICROCHIP
symbol has been defined for some time on RISCV so drop it without any
functional change.

[PATCH v3 3/3] dt-bindings: clock: mpfs-clkcfg: Add pic64gx compatibility

[Conor Dooley]

From: Pierre-Henry Moussay <pierre-henry.moussay@microchip.com>

pic64gx has a clock controller compatible with mpfs-clkcfg. Don't permit
the deprecated configuration that was never supported for this SoC.
