title: Microchip PolarFire Clock Control Module Binding
maintainers:
- Daire McNamara <daire.mcnamara@microchip.com>
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.
properties:
compatible:
const: microchip,mpfs-clkcfg
reg:
maxItems: 1
clocks:
maxItems: 1
'#clock-cells':
const: 1
description: |
The clock consumer should specify the desired clock by having the clock
ID in its "clocks" phandle cell. See include/dt-bindings/clock/microchip,mpfs-clock.h
for the full list of PolarFire clock IDs.
