1PBIAS internal regulator for SD card dual voltage i/o pads on OMAP SoCs. 2 3Required properties: 4- compatible: 5 - should be "ti,pbias-dra7" for DRA7 6 - should be "ti,pbias-omap2" for OMAP2 7 - should be "ti,pbias-omap3" for OMAP3 8 - should be "ti,pbias-omap4" for OMAP4 9 - should be "ti,pbias-omap5" for OMAP5 10 - "ti,pbias-omap" is deprecated 11- reg: pbias register offset from syscon base and size of pbias register. 12- syscon : phandle of the system control module 13- regulator-name : should be 14 pbias_mmc_omap2430 for OMAP2430, OMAP3 SoCs 15 pbias_sim_omap3 for OMAP3 SoCs 16 pbias_mmc_omap4 for OMAP4 SoCs 17 pbias_mmc_omap5 for OMAP5 and DRA7 SoC 18 19Optional properties: 20- Any optional property defined in bindings/regulator/regulator.txt 21 22Example: 23 24 pbias_regulator: pbias_regulator { 25 compatible = "ti,pbias-omap"; 26 reg = <0 0x4>; 27 syscon = <&omap5_padconf_global>; 28 pbias_mmc_reg: pbias_mmc_omap5 { 29 regulator-name = "pbias_mmc_omap5"; 30 regulator-min-microvolt = <1800000>; 31 regulator-max-microvolt = <3000000>; 32 }; 33
