+
+description: |
+ Microchip PolarFire clock control (CLKCFG) is an integrated clock controller,
+ which gates and enables all peripheral clocks.
+
+ This device tree binding describes 33 gate clocks. Clocks are referenced by
+ user nodes by the CLKCFG node phandle and the clock index in the group, from
+ 0 to 32.

+ The clock consumer should specify the desired clock by having the clock

+ description:
+ The AHB/AXI peripherals on the PolarFire SoC have reset support, so from
+ CLK_ENVM to CLK_CFM. The reset consumer should specify the desired
+ peripheral via the clock ID in its "resets" phandle cell.
+ See include/dt-bindings/clock/microchip,mpfs-clock.h for the full list of
