[PATCH 19/28] dt-bindings: mmc: Convert sdhci-pxa to json-schema

Lubomir Rintel
2020-03-17T09:40:55Z

Convert the sdhci-pxa binding to DT schema format using json-schema.

At the same time, fix a couple of issues with the examples discovered by
the validation tool -- a semicolon instead of a comma and wrong node names.

-* Marvell sdhci-pxa v2/v3 controller
-
-This file documents differences between the core properties in mmc.txt
-and the properties used by the sdhci-pxav2 and sdhci-pxav3 drivers.
-
-Required properties:
-- compatible: Should be "mrvl,pxav2-mmc", "mrvl,pxav3-mmc" or
- "marvell,armada-380-sdhci".
-- reg:
- * for "mrvl,pxav2-mmc" and "mrvl,pxav3-mmc", one register area for
- the SDHCI registers.
-
- * for "marvell,armada-380-sdhci", three register areas. The first
- one for the SDHCI registers themselves, the second one for the
- AXI/Mbus bridge registers of the SDHCI unit, the third one for the
- SDIO3 Configuration register
-- reg names: should be "sdhci", "mbus", "conf-sdio3". only mandatory
- for "marvell,armada-380-sdhci"
-- clocks: Array of clocks required for SDHCI; requires at least one for
- I/O clock.
-- clock-names: Array of names corresponding to clocks property; shall be
- "io" for I/O clock and "core" for optional core clock.
-
-Optional properties:
-- mrvl,clk-delay-cycles: Specify a number of cycles to delay for tuning.
-
-Example:
-
-sdhci@d4280800 {
- compatible = "mrvl,pxav3-mmc";
- reg = <0xd4280800 0x800>;
- bus-width = <8>;
- interrupts = <27>;
- clocks = <&chip CLKID_SDIO1XIN>, <&chip CLKID_SDIO1>;
- clock-names = "io", "core";
- non-removable;
- mrvl,clk-delay-cycles = <31>;
-};
-
-sdhci@d8000 {
- compatible = "marvell,armada-380-sdhci";
- reg-names = "sdhci", "mbus", "conf-sdio3";
- reg = <0xd8000 0x1000>,
- <0xdc000 0x100>;
- <0x18454 0x4>;
- interrupts = <0 25 0x4>;
- clocks = <&gateclk 17>;
- clock-names = "io";
- mrvl,clk-delay-cycles = <0x1F>;
-};
