This should be properly described in device tree, without this regulator core will be unable to determine the source voltage of LDOs such as LDO9 and SMPS10 which could be configured for bypass depending on the voltage requested of them. This results in conditions such as: ldo9: bypassed regulator has no supply! ldo9: failed to get the current voltage(-517) palmas-pmic 48070000.i2c:palmas@48:palmas_pmic: failed to register 48070000.i2c:palmas@48:palmas_pmic regulator Cc: Agustí Fontquerni Cc: Eduard Gavin Cc: Enric Balletbo i Serra Cc: Peter Ujfalusi Signed-off-by: Nishanth Menon [tony@atomide.com: fixed to use palmas style in-supply] Signed-off-by: Tony Lindgren --- diff --git a/arch/arm/boot/dts/omap5-board-common.dtsi b/arch/arm/boot/dts/omap5-board-common.dtsi index d0990606d16e..ebbaa140355b 100644 --- a/arch/arm/boot/dts/omap5-board-common.dtsi +++ b/arch/arm/boot/dts/omap5-board-common.dtsi @@ -14,6 +14,29 @@ display0 = &hdmi0; }; + vmain: fixedregulator-vmain { + compatible = "regulator-fixed"; + regulator-name = "vmain"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + }; + + vsys_cobra: fixedregulator-vsys_cobra { + compatible = "regulator-fixed"; + regulator-name = "vsys_cobra"; + vin-supply = <&vmain>; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + }; + + vdds_1v8_main: fixedregulator-vdds_1v8_main { + compatible = "regulator-fixed"; + regulator-name = "vdds_1v8_main"; + vin-supply = <&smps7_reg>; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; + }; + vmmcsd_fixed: fixedregulator-mmcsd { compatible = "regulator-fixed"; regulator-name = "vmmcsd_fixed"; @@ -409,6 +432,26 @@ ti,ldo6-vibrator; + smps123-in-supply = <&vsys_cobra>; + smps45-in-supply = <&vsys_cobra>; + smps6-in-supply = <&vsys_cobra>; + smps7-in-supply = <&vsys_cobra>; + smps8-in-supply = <&vsys_cobra>; + smps9-in-supply = <&vsys_cobra>; + smps10_out2-in-supply = <&vsys_cobra>; + smps10_out1-in-supply = <&vsys_cobra>; + ldo1-in-supply = <&vsys_cobra>; + ldo2-in-supply = <&vsys_cobra>; + ldo3-in-supply = <&vdds_1v8_main>; + ldo4-in-supply = <&vdds_1v8_main>; + ldo5-in-supply = <&vsys_cobra>; + ldo6-in-supply = <&vdds_1v8_main>; + ldo7-in-supply = <&vsys_cobra>; + ldo8-in-supply = <&vsys_cobra>; + ldo9-in-supply = <&vmmcsd_fixed>; + ldoln-in-supply = <&vsys_cobra>; + ldousb-in-supply = <&vsys_cobra>; + regulators { smps123_reg: smps123 { /* VDD_OPP_MPU */
