[PATCH v7] ARM: dts: sun8i: Add leds and switches on Orangepi Plus boards

[PATCH v7] ARM: dts: sun8i: Add leds and switches on Orangepi Plus boards

[Hans de Goede]

From: Krzysztof Adamski <k@japko.eu>

OrangePi Plus board has two leds - green ("pwr") and red ("status")
and two switches ("sw4" and "sw2"). This patch describes them in
devicetree.

Changes in v6 (hdegoede):
-Merge leds and r_leds nodes into one
-Fix led labels to be in <board>:<colour>:<role> form
-Alphabetically sort the added nodes
-Add support for sw2 (this is the small reset-like button)
Changes in v7 (hdegoede):
-Use PL3 / PL4 in the pinctrl node, not PL03 / PL04

An earlier version has already been sent for 4.6, please base your
changes on top of this one.

And there's a bunch of things I didn't catch at that time :/

Ah, I missed that one because it is not in your for-next branch!

It is only in sunxi-dt-for-4.6.

I'll cherry-pick the patch you've in sunxi-dt-for-4.6 into
my tree and send a fixup patch to apply on top.

Hans

As promised I will send a fixup patch for this, I was wondering
if you can push your current queue, where you've already merged
my other orangepi-plus patches somewhere, so that I can base this
fixup patch on top of it ?

Hans
