8e4422ae6b ARM: dts: imx6qdl-sabresd: Add power key support
This patch adds support for imx6qdl-sabresd board's power
key, the key is named "SW1" on board, press it can wake up
system from suspend.

Add a new pinctrl entry for gpio keys and move all gpio
keys pin to this entry.

77112dd58a ARM: dts: imx: specify the value of audmux pinctrl instead of 0x80000000
We must specify the value of audmux pinctrl if we want to use pinctrl_pm().
Thus change bypass value 0x80000000 to what we exactly need.

This patch also seperately unset PUE bit for TXD so that IOMUX won't pull
up/down the pin after turning into tristate. When we use SSI normal mode to
playback monaural audio via I2S signal, there'd be a pulled curve occur to
its signal at the second slot if setting PUE bit for TXD. And it will make
the second channel to play a constant noise. So by keeping the signal level
in the second slot, we can get a constant high level signal (-1) or a low
level one (0).

56160e3361 ARM: dts: imx6: use generic node name for fixed regulator
The device tree specification recommends that generic name should be
used for nodes.  So instead of naming those fixed regulator nodes
arbitrarily, let's use the generic name 'regulator@num' for those nodes.

817c27a128 ARM: dts: imx6qdl: make pinctrl nodes board specific
Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that
boards that share the same pinctrl setting do not have to define it time
and time again in <board>.dts.  However, along with the devices and use
cases being added continuously, the pinctrl setting nodes under iomuxc
becomes more than expected.  This bloats device tree blob for particular
board unnecessarily since only a small subset of those pinctrl setting
nodes will be used by the board.  It impacts not only the DTB file size
but also the run-time device tree lookup efficiency.

The patch moves all the pinctrl data into individual boards as needed.
With the changes, the pinctrl setting nodes becomes local to particular
board, and it makes no sense to continue numbering the setting for
given peripheral.  Thus, all the pinctrl phandler name gets updated to
have only peripheral name in there.

a94f8ecb2f ARM: imx6q: remove board specific CLKO setup
The CLKO is widely used by imx6q board designs to clock audio codec.
Since most codecs accept 24 MHz frequency, let's initially set up CLKO
with OSC24M (cko <-- cko2 <-- osc).  Then those board specific CLKO
setup for audio codec can be removed.

The board dts files also need an update on cko reference in codec node.

c56009b2f6 ARM: dts: imx: share pad macro names between imx6q and imx6dl
The imx6q and imx6dl are two pin-to-pin compatible SoCs.  The same board
design can work with either chip plugged into the socket, e.g. sabresd
and sabreauto boards.

We currently define pin groups in imx6q.dtsi and imx6dl.dtsi
respectively because the pad macro names are different between two
chips.  This brings a maintenance burden on having the same label point
to the same pin group defined in two places.

The patch replaces prefix MX6Q_ and MX6DL_ with MX6QDL_ for both SoCs
pad macro names.  Then the pin groups becomes completely common between
imx6q and imx6dl and can just be moved into imx6qdl.dtsi, so that the
long term maintenance of imx6q/dt pin settings becomes easier.

Unfortunately, the change brings some dramatic diff stat, but it's all
about DTS file, and the ultimate net diff stat is good.
