[PATCH v2 2/9] ARM: tegra: lg-x3: Remove pinctrl-* properties duplication

[Svyatoslav Ryhel]

The pinctrl-names and pinctrl-0 are defined in the common device tree,
having them in the individual trees is redundant. Remove them.

[PATCH v2 9/9] ARM: tegra: p895: Update power LED trigger

[Svyatoslav Ryhel]

The previous "battery-charging" trigger was unreliable and slow to update.
Since LG X3 devices now have a charger driver, use
"max8971-charger-online" instead. Tested on the LG Optimus Vu P895; it
works much more reliably.
