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

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>;
