-* 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:

- - "renesas,sh73a0-mstp-clocks" for SH73A0 (SH-MobileAG5) MSTP gate clocks
- and "renesas,cpg-mstp-clocks" as a fallback.
- - 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
- - clock-indices: Indices of the gate clocks into the group (0 to 31)
-
-The clocks, clock-output-names and clock-indices properties contain one entry
-per gate clock. The MSTP groups are sparsely populated. Unimplemented gate
-clocks must not be declared.
