[PATCH v4] ARM: dts: pxa: add mioa701 board description

Robert Jarzmik
2018-09-15T11:02:06Z

Add device-tree description of the Mitac MIO A701 board.
This is aimed at replacing mioa701.c board file, and once stabilized,
the leftover, such as the suspend resume mechanics will rely on a new
IPL, and not the legacy Windows CE one.

Since v1: fix lcd_supply and lcd_backlight
These were depending on my internal tree changes, fit it.
Since v2: take into account Rob's comments
Since v3: take into account Marcel's comments

This patch deserves some special "love review". As it will probably
serve for a more broad pxa conversion to devicetree of the other boards,
and because it touches almost all domains for a pxa platform (camera,
video, audio, i2c, ...), it should be as clean as possible so that
mistakes are not carried on ...

Therefore I expect the review of this one to be long (ie. it won't land
for v4.19), until it looks good enough.
