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>.

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.

Add support for VAR-SOM-OM44[1] SODIMM system on module from
Variscite. SoM features a OMAP4460, 1GB RAM, Gigabit Ethernet
(LAN7500) and optional WLAN/BT.
Also add support for VAR-STK-OM44 development board from
Variscite. This kit features a VAR-SOM-OM44 and the carrier board
VAR-OM44CustomBoard[2]. The VAR-STK-OM44 is the same as
VAR-DVK-OM44 but without the LCD display.
omap4-var-stk-om44.dts replace the old and very limited
omap4-var-som.dts.
