1I2C for OMAP platforms 2 3Required properties : 4- compatible : Must be 5 "ti,omap2420-i2c" for OMAP2420 SoCs 6 "ti,omap2430-i2c" for OMAP2430 SoCs 7 "ti,omap3-i2c" for OMAP3 SoCs 8 "ti,omap4-i2c" for OMAP4+ SoCs 9 "ti,am654-i2c", "ti,omap4-i2c" for AM654 SoCs 10 "ti,j721e-i2c", "ti,omap4-i2c" for J721E SoCs 11- ti,hwmods : Must be "i2c<n>", n being the instance number (1-based) 12- #address-cells = <1>; 13- #size-cells = <0>; 14 15Recommended properties : 16- clock-frequency : Desired I2C bus clock frequency in Hz. Otherwise 17 the default 100 kHz frequency will be used. 18 19Optional properties: 20- Child nodes conforming to i2c bus binding 21 22Note: Current implementation will fetch base address, irq and dma 23from omap hwmod data base during device registration. 24Future plan is to migrate hwmod data base contents into device tree 25blob so that, all the required data will be used from device tree dts 26file. 27 28Examples : 29 30i2c1: i2c@0 { 31 compatible = "ti,omap3-i2c"; 32 #address-cells = <1>; 33 #size-cells = <0>; 34 ti,hwmods = "i2c1"; 35 clock-frequency = <400000>; 36}; 37
