Add the driver for the clock gate control which uses PSC (Power Sleep Controller) IP on Keystone 2 based SOCs. It is responsible for enabling and disabling of the clocks for different IPs present in the SoC.

Binding for Keystone gate control driver which uses PSC controller IP.
|
|
|
|
This binding uses the common clock binding[1].
|
|
|
|
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
|
|
|
|
Required properties:
|
|
- compatible : shall be "ti,keystone,psc-clock".
|
|
- #clock-cells : from common clock binding; shall be set to 0.
|
|
- clocks : parent clock phandle
|
|
- reg : psc control and domain address address space
|
|
- reg-names : psc control and domain registers
|
|
- domain-id : psc domain id needed to check the transition state register
|
|
|
|
Optional properties:
|
|
- clock-output-names : From common clock binding to override the
|
|
default output clock name
|
|
Example:
|
|
clkusb: clkusb {
|
|
#clock-cells = <0>;
|
|
compatible = "ti,keystone,psc-clock";
|
|
clocks = <&chipclk16>;
|
|
clock-output-names = "usb";
|
|
reg = <0x02350008 0xb00>, <0x02350000 0x400>;
|
|
reg-names = "control", "domain";
|
|
domain-id = <0>;
|
|
};
