[PATCH] dt-bindings: clock: ti,keystone-gate: Convert to DT schema
From: Bhargav Joshi
Date: Sat Jul 25 2026 - 16:05:16 EST
Convert Texas Instruments keystone PSC clock binding to DT schema.
The vendor-specific 'domain-id' property is intentionally kept without a
"ti," prefix to preserve existing ABI since driver and existing board
file use property without "ti," prefix.
Also update the reference to this binding in ti,keystone-rproc.txt to
point at the new filename.

-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>;
- };
