This patchset adds support for LG Nexus 5 phone, codenamed hammerhead.
Initial version have following supported,
- Serial console over headphone jack
- pm8841 and pm8941 regulator nodes
- Hardware keys (volume_up and volume_down)
Values for the regulator nodes are taken from following files in downstream msm
kernel tree, branch android-msm-hammerhead-3.4-marshmallow-mr2
- arch/arm/boot/dts/msm8974-regulator.dtsi
- arch/arm/boot/dts/msm8974-hammerhead/msm8974-hammerhead.dtsi
Values are verified against kmsg from downstream kernel as well.
However, it seems regulator-max-microvolt settings are not respected, for example,
l19{
regulator-min-microvolt = <3000000>;
regulator-max-microvolt = <3300000>;
};
but in kmsg, it says,
[ 1.753401] l19: supplied by vph-pwr
[ 1.757418] l19: Bringing 0uV into 3000000-3000000uV
Relavant line from kmsg of downstream kernel says,
[ 0.255590] 8941_l19: 3000 <--> 3300 mV at 3300 mV normal idle
Is there anything wrong with dts?
