1 | PBIAS internal regulator for SD card dual voltage i/o pads on OMAP SoCs. |
| 2 | ||
| 3 | Required properties: | |
| 4 | - compatible: | |
| 5 | - "ti,pbias-omap" for OMAP2, OMAP3, OMAP4, OMAP5, DRA7. | |
| 6 | - reg: pbias register offset from syscon base and size of pbias register. | |
| 7 | - syscon : phandle of the system control module | |
| 8 | - regulator-name : should be | |
| 9 | pbias_mmc_omap2430 for OMAP2430, OMAP3 SoCs | |
| 10 | pbias_sim_omap3 for OMAP3 SoCs | |
| 11 | pbias_mmc_omap4 for OMAP4 SoCs | |
| 12 | pbias_mmc_omap5 for OMAP5 and DRA7 SoC | |
