On i.MX6SX SDB board, vgen6 supplies vdd1p1/vdd2p5 LDO and sw2 supplies vdd3p0 LDO, this patch assigns corresponding power supply for vdd1p1/vdd2p5/vdd3p0 to avoid confusion by below log: vdd1p1: supplied by regulator-dummy vdd3p0: supplied by regulator-dummy vdd2p5: supplied by regulator-dummy With this patch, the power supply is more accurate: vdd1p1: supplied by VGEN6 vdd3p0: supplied by SW2 vdd2p5: supplied by VGEN6 Signed-off-by: Anson Huang <Anson.Huang@xxxxxxx> --- arch/arm/boot/dts/imx6sx-sdb-reva.dts | 12 ++++++++++++ arch/arm/boot/dts/imx6sx-sdb.dts | 12 ++++++++++++ arch/arm/boot/dts/imx6sx.dtsi | 6 +++--- 3 files changed, 27 insertions(+), 3 deletions(-) diff --git a/arch/arm/boot/dts/imx6sx-sdb-reva.dts b/arch/arm/boot/dts/imx6sx-sdb-reva.dts index 00c4854..5b3d6c10 100644 --- a/arch/arm/boot/dts/imx6sx-sdb-reva.dts +++ b/arch/arm/boot/dts/imx6sx-sdb-reva.dts @@ -154,3 +154,15 @@ enable-active-high; vin-supply = <®_can_en>; }; + +®_vdd1p1 { + vin-supply = <&vgen6_reg>; +}; + +®_vdd3p0 { + vin-supply = <&sw2_reg>; +}; + +®_vdd2p5 { + vin-supply = <&vgen6_reg>; +}; diff --git a/arch/arm/boot/dts/imx6sx-sdb.dts b/arch/arm/boot/dts/imx6sx-sdb.dts index 998e3e1..10f6da8 100644 --- a/arch/arm/boot/dts/imx6sx-sdb.dts +++ b/arch/arm/boot/dts/imx6sx-sdb.dts @@ -137,6 +137,18 @@ vin-supply = <&sw1a_reg>; }; +®_vdd1p1 { + vin-supply = <&vgen6_reg>; +}; + +®_vdd3p0 { + vin-supply = <&sw2_reg>; +}; + +®_vdd2p5 { + vin-supply = <&vgen6_reg>; +}; + ®_can_stby { /* Transceiver EN/STBY is active low on RevB board */ gpio = <&gpio4 27 GPIO_ACTIVE_LOW>; diff --git a/arch/arm/boot/dts/imx6sx.dtsi b/arch/arm/boot/dts/imx6sx.dtsi index b16a123..bbdfdd8 100644 --- a/arch/arm/boot/dts/imx6sx.dtsi +++ b/arch/arm/boot/dts/imx6sx.dtsi @@ -600,7 +600,7 @@ <GIC_SPI 54 IRQ_TYPE_LEVEL_HIGH>, <GIC_SPI 127 IRQ_TYPE_LEVEL_HIGH>; - regulator-1p1 { + reg_vdd1p1: regulator-1p1 { compatible = "fsl,anatop-regulator"; regulator-name = "vdd1p1"; regulator-min-microvolt = <1000000>; @@ -615,7 +615,7 @@ anatop-enable-bit = <0>; }; - regulator-3p0 { + reg_vdd3p0: regulator-3p0 { compatible = "fsl,anatop-regulator"; regulator-name = "vdd3p0"; regulator-min-microvolt = <2800000>; @@ -630,7 +630,7 @@ anatop-enable-bit = <0>; }; - regulator-2p5 { + reg_vdd2p5: regulator-2p5 { compatible = "fsl,anatop-regulator"; regulator-name = "vdd2p5"; regulator-min-microvolt = <2250000>; -- 2.7.4
