From: Peng Fan <peng.fan@xxxxxxx> Per PCA9450C datasheet, the voltage range as below: BUCK1 0.6 - 2.1875 BUCK2 0.6 - 2.1875 BUCK4 0.6 - 3.4 BUCK5 0.6 - 3.4 BUCK6 0.6 - 3.4 LDO1 1.6-1.9, 3.0-3.3 LDO2 0.8 – 1.15 LDO3 0.8 - 3.3 LDO4 0.8 - 3.3 LDO5 1.8 - 3.3 Currently we set the board voltage range same as PMIC regulator range. Also add LDO[2,4] in this patch Fixes: 5497bc2a2bff ("arm64: dts: imx8mp-evk: Add PMIC device") Signed-off-by: Peng Fan <peng.fan@xxxxxxx> --- arch/arm64/boot/dts/freescale/imx8mp-evk.dts | 44 +++++++++++++------- 1 file changed, 30 insertions(+), 14 deletions(-) diff --git a/arch/arm64/boot/dts/freescale/imx8mp-evk.dts b/arch/arm64/boot/dts/freescale/imx8mp-evk.dts index b4c1ef2559f2..a4cddc5a8620 100644 --- a/arch/arm64/boot/dts/freescale/imx8mp-evk.dts +++ b/arch/arm64/boot/dts/freescale/imx8mp-evk.dts @@ -248,8 +248,8 @@ pmic@25 { regulators { BUCK1 { regulator-name = "BUCK1"; - regulator-min-microvolt = <720000>; - regulator-max-microvolt = <1000000>; + regulator-min-microvolt = <600000>; + regulator-max-microvolt = <2187500>; regulator-boot-on; regulator-always-on; regulator-ramp-delay = <3125>; @@ -257,8 +257,8 @@ BUCK1 { reg_arm: BUCK2 { regulator-name = "BUCK2"; - regulator-min-microvolt = <720000>; - regulator-max-microvolt = <1025000>; + regulator-min-microvolt = <600000>; + regulator-max-microvolt = <2187500>; regulator-boot-on; regulator-always-on; regulator-ramp-delay = <3125>; @@ -268,40 +268,56 @@ reg_arm: BUCK2 { BUCK4 { regulator-name = "BUCK4"; - regulator-min-microvolt = <3000000>; - regulator-max-microvolt = <3600000>; + regulator-min-microvolt = <600000>; + regulator-max-microvolt = <3400000>; regulator-boot-on; regulator-always-on; }; BUCK5 { regulator-name = "BUCK5"; - regulator-min-microvolt = <1650000>; - regulator-max-microvolt = <1950000>; + regulator-min-microvolt = <600000>; + regulator-max-microvolt = <3400000>; regulator-boot-on; regulator-always-on; }; BUCK6 { regulator-name = "BUCK6"; - regulator-min-microvolt = <1045000>; - regulator-max-microvolt = <1155000>; + regulator-min-microvolt = <600000>; + regulator-max-microvolt = <3400000>; regulator-boot-on; regulator-always-on; }; LDO1 { regulator-name = "LDO1"; - regulator-min-microvolt = <1650000>; - regulator-max-microvolt = <1950000>; + regulator-min-microvolt = <1600000>; + regulator-max-microvolt = <3300000>; + regulator-boot-on; + regulator-always-on; + }; + + LDO2 { + regulator-name = "LDO2"; + regulator-min-microvolt = <800000>; + regulator-max-microvolt = <1150000>; regulator-boot-on; regulator-always-on; }; LDO3 { regulator-name = "LDO3"; - regulator-min-microvolt = <1710000>; - regulator-max-microvolt = <1890000>; + regulator-min-microvolt = <800000>; + regulator-max-microvolt = <3300000>; + regulator-boot-on; + regulator-always-on; + }; + + ldo4: LDO4 { + regulator-name = "LDO4"; + regulator-min-microvolt = <800000>; + regulator-max-microvolt = <3300000>; regulator-boot-on; regulator-always-on; }; -- 2.37.1
