* 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,r7s72100-mstp-clocks" for R7S72100 (RZ) MSTP gate clocks
|
|
- "renesas,r8a7779-mstp-clocks" for R8A7779 (R-Car H1) MSTP gate clocks
|
|
- "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,clock-indices: Indices of the gate clocks into the group (0 to 31)
|
|
|
|
The clocks, clock-output-names and renesas,clock-indices properties contain one
|
|
entry per gate clock. The MSTP groups are sparsely populated. Unimplemented
|
|
gate clocks must not be declared.
|
|
|
