[PATCH v3 0/5] 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.

Changes since v2:

    - rename vph-pwr-reg node to vreg-vph-pwr
    - also move pinctrl stuff to msm8974.dtsi

Changes since v1:

    - Remove qcom,msm-id from dts file
    - Add "lge,hammerhead" to compatible
    - move vreg_boost node from honami.dts file to msm8974.dtsi
    - move vph-pwr-reg node to msm8974.dtsi
