Kernel-4.18.0-80.el8_pbias-regulator

PBIAS internal regulator for SD card dual voltage i/o pads on OMAP SoCs.

Required properties:

  • compatible:
    • should be “ti,pbias-dra7” for DRA7
    • should be “ti,pbias-omap2” for OMAP2
    • should be “ti,pbias-omap3” for OMAP3
    • should be “ti,pbias-omap4” for OMAP4
    • should be “ti,pbias-omap5” for OMAP5
    • “ti,pbias-omap” is deprecated
  • reg: pbias register offset from syscon base and size of pbias register.
  • syscon : phandle of the system control module
  • regulator-name : should be
          pbias_mmc_omap2430 for OMAP2430, OMAP3 SoCs
          pbias_sim_omap3 for OMAP3 SoCs
          pbias_mmc_omap4 for OMAP4 SoCs
          pbias_mmc_omap5 for OMAP5 and DRA7 SoC
    

Optional properties:

  • Any optional property defined in bindings/regulator/regulator.txt

Example:

    pbias_regulator: pbias_regulator {
        compatible = "ti,pbias-omap";
        reg = <0 0x4>;
        syscon = <&omap5_padconf_global>;
        pbias_mmc_reg: pbias_mmc_omap5 {
            regulator-name = "pbias_mmc_omap5";
            regulator-min-microvolt = <1800000>;
            regulator-max-microvolt = <3000000>;
        };
