Kernel-4.18.0-80.el8_marvell,mmp2

  • Marvell MMP2 Clock Controller

The MMP2 clock subsystem generates and supplies clock to various
controllers within the MMP2 SoC.

Required Properties:

  • compatible: should be one of the following.

    • “marvell,mmp2-clock” - controller compatible with MMP2 SoC.
  • reg: physical base address of the clock subsystem and length of memory mapped
    region. There are 3 places in SOC has clock control logic:
    “mpmu”, “apmu”, “apbc”. So three reg spaces need to be defined.

  • #clock-cells: should be 1.

  • #reset-cells: should be 1.

Each clock is assigned an identifier and client nodes use this identifier
to specify the clock which they consume.

All these identifier could be found in <dt-bindings/clock/marvell-mmp2.h>.
