Enable support for various hw found on the Samsung Galaxy S5: - touchkey (the two buttons around the home button) - touchscreen - notification led - wifi - external SD card Please note that for working wifi the correct firmware is needed. Check [1] for links and locations. Also note, that to actually run a mainline kernel on the klte, you'd need to apply this patch [2]. Any feedback on getting this to run on pure mainline are welcome.

commit cd13c72c1853f219e1f ("ARM: dts: qcom: msm8974-klte: Add max77826
pmic node") and commit 8bf7a360a92cc6b2aebc8 ("ARM: dts: qcom:
msm8974-klte: Add sdhci1 node") both added pinctrl node. This patch merges
the two nodes.
