   2
   3 Required 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
