Javier Martinez Canillas e98ceb23e4 ARM: dts: am437x-sk-evm: Use AM4372_IOPAD pinmux macro
Use the pinmux IOPAD macro to define the register absolute physical
address instead of the offset from the padconf base address. This
makes the DTS easier to read since matches the addresses listed in
the Technical Reference Manual.

Linus Torvalds c0d6fe2f01 ARM: DT updates for v4.4
As usual, this is the massive branch we have for each release. Lots of
 various updates and additions of hardware descriptions on existing hardware,
 as well as the usual additions of new boards and SoCs.
 
 This is also the first release where we've started mixing 64- and 32-bit
 DT updates in one branch.
 
 (Specific details on what's actually here and new is pretty easy to tell
 from the diffstat, so there's little point in duplicating listing it here.)

Mugunthan V N 0731cbdd5f ARM: dts: am43xx: fix cd-gpios definition as per hardware design and dt binding docs
As per mmc device tree binding documentation card detect gpio has
to be active low signal. When a hardware is designed with active
high card detect, gpio polarity has to be changed with
cd-inverted dt property.

In AM43xx the card detect gpio is designed as active low gpio.
So correcting the dt card detect gpio definition.

Felipe Balbi faa4ec1eed ARM: dts: am437x-sk: fix for new newhaven display module revision
AM437x Starter Kit uses a NewHaven Display module with
a 4.3" display and EDT FT5306 touchscreen

On that module's new revision, NewHave decided to change
the pinout on the 6 pin flat-pcb touchscreen connector so
that instead of having WAKE pin, we now have RESETn.

The new display module is available on AM437x SK Beta and
all new revisions while the older revision is only available
on AM437x SK Alpha which, unfortunately, can't be supported
anymore in mainline without a revert of this patch.

Marc Zyngier 7136d457f3 ARM: omap: convert wakeupgen to stacked domains
OMAP4/5 has been (ab)using the gic_arch_extn to provide
wakeup from suspend, and it makes a lot of sense to convert
this code to use stacked domains instead.

This patch does just this, updating the DT files to actually
reflect what the HW provides.

BIG FAT WARNING: because the DTs were so far lying by not
exposing the WUGEN HW block, kernels with this patch applied
won't have any suspend-resume facility when booted with old DTs,
and old kernels with updated DTs won't even boot.

On a platform with this patch applied, the system looks like

Tomi Valkeinen d73f825e6e ARM: dts: am437x-sk-evm.dts: fix LCD timings
The lcd0 node for am437x-sk-evm.dts contains bad LCD timings, and while
they seem to work with a quick test, doing for example blank/unblank
will give you a black display.

This patch updates the timings to the 'typical' values from the LCD spec
sheet.

Also, the compatible string is completely bogus, as
"osddisplays,osd057T0559-34ts" is _not_ a 480x272 panel. The panel on
the board is a newhaven one. Update the compatible string to reflect
this. Note that this hasn't caused any issues, as the "panel-dpi"
matches the driver.

Luckily ball D25 (offset 0x238 - gpio5_8) on AM437x
isn't used for anything.

While at that, also replace a pullup with a pulldown
as that gpio should be normally low, not high.
