SW4 is one power rail for LPDDR2 on i.mx6sl-evk, so it should
be kept always on. But it's disabled after switch disabled
interface implemented in pfuze driver
'commit 5fe156f1cab4
("regulator: pfuze100: add enable/disable for switch")'.Thus,
it breaks kernel bootup. Add 'regulator-always-on' for SW4.Signed-off-by: Robin Gong <[email protected]> --- arch/arm/boot/dts/imx6sl-evk.dts | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm/boot/dts/imx6sl-evk.dts b/arch/arm/boot/dts/imx6sl-evk.dts index 37e792f..798df66 100644 --- a/arch/arm/boot/dts/imx6sl-evk.dts +++ b/arch/arm/boot/dts/imx6sl-evk.dts @@ -199,6 +199,7 @@ sw4_reg: sw4 { regulator-min-microvolt = <800000>; regulator-max-microvolt = <3300000>; + regulator-always-on; }; swbst_reg: swbst { -- 2.7.4
