* Renesas CPG Module Stop (MSTP) Clocks
The CPG can gate SoC device clocks. The gates are organized in groups of up to
32 gates.
This device tree binding describes a single 32 gate clocks group per node.
Clocks are referenced by user nodes by the MSTP node phandle and the clock
index in the group, from 0 to 31.
Required Properties:
- compatible: Must be one of the following
- "renesas,r8a7790-mstp-clocks" for R8A7790 (R-Car H2) MSTP gate clocks
- "renesas,r8a7791-mstp-clocks" for R8A7791 (R-Car M2) MSTP gate clocks
- "renesas,cpg-mstp-clock" for generic MSTP gate clocks
- reg: Base address and length of the I/O mapped registers used by the MSTP
clocks. The first register is the clock control register and is mandatory.
The second register is the clock status register and is optional when not
implemented in hardware.
- clocks: Reference to the parent clocks, one per output clock. The parents
must appear in the same order as the output clocks.
- #clock-cells: Must be 1
- clock-output-names: The name of the clocks as free-form strings
- renesas,indices: Indices of the gate clocks into the group (0 to 31)
The clocks, clock-output-names and renesas,indices properties contain one
entry per gate clock. The MSTP groups are sparsely populated. Unimplemented
gate clocks must not be declared.
