[PATCH 0/3] Initial support for LG Nexus 5 phone (hammerhead)

[Bhushan Shah]

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?
