731b409878 ARM: dts: Configure duovero for to allow core retention during idle
By reconfiguring few GPIOs in the dts file we can make duovero parlor
hit retention during idle:

1. Let's a larger debounce value for gpio-keys

This will then make gpio-keys use software debounce and the GPIO
debounce clock is not enabled.

2. Let's allow WLAN suspend for mwifiex

This can be done just by adding keep-power-in-suspend.

3. Let's reconfigure smsc911x driver to use GPIO edge interrupt

This will allow using NFSroot while the system idles, and the kernel
has quite a few dts files with "smsc,lan9115" compatible using edge
interrupts.

Then to have the system hit core retention during idle, the UARTs
needs to be idled and USB modules need to be unloaded or unbound.

3a8ed20db8 ARM: dts: Disable HDMI CEC internal pull-ups
Devices using an external encoder, ESD protection and level shifter
such as tpd12s015 or ip4791cz12 have the CEC pull in the encoder
chip. And on var-som-om44, there is external pull up resistor R30.

So the internal CEC pull-up resistor needs to be disabled as otherwise
the external and internal pull are parallel making the pull value
much smaller than intended. This leads into the CEC not working as
reported by Hans Verkuil <hverkuil@xs4all.nl>.

6d1c244803 ARM: DT updates for v4.5
As usual, the bulk of this release is again DT file contents.
 
 There's a huge number of changes here, and it's challenging to give a crisp
 overview of just what is in here. To start with:
 
 New boards:
 
 - TI-based DM3730 from LogicPD (Torpedo)
 - Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
 - Raspberry Pi 2 DT files
 - Watchdog on Meson8b
 - Veyron-mickey (ASUS Chromebit) DTS
 - Rockchip rk3228 SoC and eval board
 - Sigma Designs Tango4
 
 Improvements:
 
 - Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
 - Misc new devices for Rockchip rk3036 and rk3288
 - Allwinner updates for misc SoCs and systems
 
 ... and a _large_ number of other changes across the field. Devices
 added to SoC DTSI and board DTS files for a number of SoC vendors, new
 product boards on already-supported SoCs, cleanups and refactorings of
 existing DTS/DTSI files and a bunch of other changes.

0c4d63b323 ARM: dts: omap: replace legacy *,wakeup property with wakeup-source
Though the keyboard and other driver will continue to support the legacy
"gpio-key,wakeup", "linux,wakeup" boolean property to enable the wakeup
source, "wakeup-source" is the new standard binding.

This patch replaces all the legacy wakeup properties with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.

This attaches VDAC (vdda_hdmi_dac) to HDMI's vdda-supply.
