Subject: [PATCH v2] spi: dt-bindings: jcore,spi: convert spi-jcore to dtschema
Date: Thu, 21 Mar 2024 23:32:28 +0530	[thread overview]
Message-ID: <20240321180617.35390-1-five231003@gmail.com> (raw)

Convert existing bindings of J-Core spi2 to dtschema.

No new properties are added.

Changes since v1:
- changed the subject line to conform.
- dropped desc for "clock" and "clock-names" properties.
- cleaned up stuff.

Thanks for the review Krzysztof.

-J-Core SPI master
-
-Required properties:
-
-- compatible: Must be "jcore,spi2".
-
-- reg: Memory region for registers.
-
-- #address-cells: Must be 1.
-
-- #size-cells: Must be 0.
-
-Optional properties:
-
-- clocks: If a phandle named "ref_clk" is present, SPI clock speed
-  programming is relative to the frequency of the indicated clock.
-  Necessary only if the input clock rate is something other than a
-  fixed 50 MHz.
-
-- clock-names: Clock names, one for each phandle in clocks.
-
-See spi-bus.txt for additional properties not specific to this device.
-
-Example:
-
-spi@40 {
-	compatible = "jcore,spi2";
-	#address-cells = <1>;
-	#size-cells = <0>;
-	reg = <0x40 0x8>;
-	spi-max-frequency = <25000000>;
-	clocks = <&bus_clk>;
-	clock-names = "ref_clk";
