Renesas DIV6 clocks provide a single clock output. Hence make the "clock-output-names" DT property optional instead of mandatory. In case the DT property is omitted the DT node name will be used. Rename the variable "name" to "clk_name" to make the code more similar with fixed-factor-clock.c, and to avoid a conflict with a nested local variable while we're at it.

* Renesas CPG DIV6 Clock
|
|
|
|
The CPG DIV6 clocks are variable factor clocks provided by the Clock Pulse
|
|
Generator (CPG). Their clock input is divided by a configurable factor from 1
|
|
to 64.
|
|
|
|
Required Properties:
|
|
|
|
- compatible: Must be one of the following
|
|
- "renesas,r8a73a4-div6-clock" for R8A73A4 (R-Mobile APE6) DIV6 clocks
|
|
- "renesas,r8a7740-div6-clock" for R8A7740 (R-Mobile A1) DIV6 clocks
|
|
- "renesas,r8a7790-div6-clock" for R8A7790 (R-Car H2) DIV6 clocks
|
|
- "renesas,r8a7791-div6-clock" for R8A7791 (R-Car M2-W) DIV6 clocks
|
|
- "renesas,r8a7793-div6-clock" for R8A7793 (R-Car M2-N) DIV6 clocks
|
|
- "renesas,r8a7794-div6-clock" for R8A7794 (R-Car E2) DIV6 clocks
|
|
- "renesas,sh73a0-div6-clock" for SH73A0 (SH-Mobile AG5) DIV6 clocks
|
|
and "renesas,cpg-div6-clock" as a fallback.
|
|
- reg: Base address and length of the memory resource used by the DIV6 clock
|
|
- clocks: Reference to the parent clock(s); either one, four, or eight
|
|
clocks must be specified. For clocks with multiple parents, invalid
|
|
settings must be specified as "<0>".
|
|
- #clock-cells: Must be 0
|
|
|
|
|
|
Optional Properties:
|
|
|
|
- clock-output-names: The name of the clock as a free-form string
|
|
|
|
|
|
Example
|
|
-------
|
|
|
|
sdhi2_clk: sdhi2_clk@e615007c {

|
|
reg = <0 0xe615007c 0 4>;
|
|
clocks = <&pll1_div2_clk>, <&cpg_clocks R8A73A4_CLK_PLL2S>,
|
|
<0>, <&extal2_clk>;
|
|
#clock-cells = <0>;
