-I2C for OMAP platforms
-
-Required properties :
-- compatible : Must be
- "ti,omap2420-i2c" for OMAP2420 SoCs
- "ti,omap2430-i2c" for OMAP2430 SoCs
- "ti,omap3-i2c" for OMAP3 SoCs
- "ti,omap4-i2c" for OMAP4+ SoCs
- "ti,am654-i2c", "ti,omap4-i2c" for AM654 SoCs
- "ti,j721e-i2c", "ti,omap4-i2c" for J721E SoCs
- "ti,am64-i2c", "ti,omap4-i2c" for AM64 SoCs
-- ti,hwmods : Must be "i2c<n>", n being the instance number (1-based)
-- #address-cells = <1>;
-- #size-cells = <0>;
-
-Recommended properties :
-- clock-frequency : Desired I2C bus clock frequency in Hz. Otherwise
- the default 100 kHz frequency will be used.
-
-Optional properties:
-- Child nodes conforming to i2c bus binding
-
-Note: Current implementation will fetch base address, irq and dma
-from omap hwmod data base during device registration.
-Future plan is to migrate hwmod data base contents into device tree
-blob so that, all the required data will be used from device tree dts
-file.
-
-Examples :
-
-i2c1: i2c@0 {
- compatible = "ti,omap3-i2c";
- #address-cells = <1>;
- #size-cells = <0>;
- ti,hwmods = "i2c1";
- clock-frequency = <400000>;
-};

Convert i2c-omap.txt to YAML schema for better checks and documentation. Following properties were used in DT but were not documented in txt bindings and has been included in YAML schema: 1. Include ti,am4372-i2c compatible 2. Include dmas property used in few OMAP dts files 3. Document clocks property Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> --- .../devicetree/bindings/i2c/i2c-omap.txt | 37 --------- .../devicetree/bindings/i2c/ti,omap4-i2c.yaml | 75 +++++++++++++++++++ 2 files changed, 75 insertions(+), 37 deletions(-) delete mode 100644 Documentation/devicetree/bindings/i2c/i2c-omap.txt create mode 100644 Documentation/devicetree/bindings/i2c/ti,omap4-i2c.yaml
