DIV6 clocks are divider gate clocks controlled through a single register. The divider is expressed on 6 bits, hence the name, and can take values from 1/1 to 1/64. Those clocks are found on Renesas ARM SoCs. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>

* Renesas CPG DIV6 Clock
|
|
|
|
The CPG DIV6 clocks are variable factor clocks provided by the Clock Pulse
|
|
Generator (CPG). They clock input is divided by a configurable factor from 1
|
|
to 64.
|
|
|
|
Required Properties:
|
|
|
|
- compatible: Must be one of the following
|
|
- "renesas,r8a7790-div6-clock" for R8A7790 (R-Car H2) DIV6 clocks
|
|
- "renesas,r8a7791-div6-clock" for R8A7791 (R-Car M2) DIV6 clocks
|
|
- "renesas,cpg-div6-clock" for generic DIV6 clocks
|
|
- reg: Base address and length of the memory resource used by the DIV6 clock
|
|
- clocks: Reference to the parent clock
|
|
- #clock-cells: Must be 0
|
|
- clock-output-names: The name of the clock as a free-form string
