This is going to the fixes so it needs a good explanation. When I posted the patch[1], I refer to the old schematic document of both TM2 and TM2E. [1] 01e5d2352152 ("arm64: dts: exynos: Add dts file for Exynos5433-based TM2 board") After checking the highest version of schematic document of both TM2 and TM2E, there is no difference of ldo23/ldo25 on both TM2 and TM2E. - ldo23 is used on TM2/TM2E, but the name/max-microvolt are wrong. - ldo25 isn't used on TM2/TM2E. (not connected) Because ldo23 and lod25 are not used on other device in Exynos5433 and TM2 board. this patch does not affect the operation to system/user. > >> >> Fixes: 01e5d2352152 ("arm64: dts: exynos: Add dts file for Exynos5433-based TM2 board") >> Signed-off-by: Chanwoo Choi <cw00.choi@xxxxxxxxxxx> >> Signed-off-by: Andi Shyti <andi.shyti@xxxxxxxxxxx> >> Signed-off-by: Jaechul Lee <jcsing.lee@xxxxxxxxxxx> >> --- >> arch/arm64/boot/dts/exynos/exynos5433-tm2.dts | 7 ++++--- >> arch/arm64/boot/dts/exynos/exynos5433-tm2e.dts | 10 ---------- >> 2 files changed, 4 insertions(+), 13 deletions(-) >> >> diff --git a/arch/arm64/boot/dts/exynos/exynos5433-tm2.dts b/arch/arm64/boot/dts/exynos/exynos5433-tm2.dts >> index 3b5215c..e8971f4 100644 >> --- a/arch/arm64/boot/dts/exynos/exynos5433-tm2.dts >> +++ b/arch/arm64/boot/dts/exynos/exynos5433-tm2.dts >> @@ -504,9 +504,9 @@ >> }; >> >> ldo23_reg: LDO23 { >> - regulator-name = "CAM_SEN_CORE_1.2V_AP"; >> + regulator-name = "CAM_SEN_CORE_1.05V_AP"; >> regulator-min-microvolt = <1050000>; >> - regulator-max-microvolt = <1200000>; >> + regulator-max-microvolt = <1050000>; >> }; >> >> ldo24_reg: LDO24 { >> @@ -516,9 +516,10 @@ >> }; >> >> ldo25_reg: LDO25 { >> - regulator-name = "CAM_SEN_A2.8V_AP"; >> + regulator-name = "UNUSED_LDO25"; >> regulator-min-microvolt = <2800000>; >> regulator-max-microvolt = <2800000>; >> + regulator-always-off; > > Don't add it.
