The at24 driver allows to register I2C EEPROM chips using different vendor
and devices, but the I2C subsystem does not take the vendor into account
when matching using the I2C table since it only has device entries.
But when matching using an OF table, both the vendor and device has to be
taken into account so the driver defines only a set of compatible strings
using the "atmel" vendor as a generic fallback for compatible I2C devices.
So add this generic fallback to the device node compatible string to make
the device to match the driver using the OF device ID table.

The hpd pin of the second hdmi connector of the Utilite Pro is wired
up to a gpio pin of the SoC. Reflect this in the device tree.

Apart from the already enabled Designware HDMI port, the Utilite Pro
has a second display pipeline which has the following shape:
IPU1 DI0 --> Parallel display --> tfp410 rgb24 to DVI encoder
--> HDMI connector.
Enable support for it.
In addition, since this pipeline is hardwired to IPU1, sever the link
between IPU1 and the SoC-internal Designware HDMI encoder forcing the
latter to be connected to IPU2 instead of IPU1. Otherwise, it is not
possible to drive both displays at high resolution due to the bandwidth
limitations of a single IPU.

Though the keyboard driver for GPIO buttons(gpio-keys) will continue to
check for/support the legacy "gpio-key,wakeup" boolean property to
enable gpio buttons as wakeup source, "wakeup-source" is the new
standard binding.
This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property in order to avoid any further copy-paste
duplication.

It turns out that the i2c1 adapter is connected to a multiplexer
controlled by a gpio line. The first (default) mux option connects
i2c1 to a bus connected to the already known peripherals. The other
one connects the adapter to the ddc pins of the DVI port.

The Utilite Pro has a mmc card slot connected to the usdhc3
controller. There is no card detection until hardware revision 1.3.
Add support for it and signal the controller with the broken-cd
property that polling has to be used to detect a card.

The CompuLab Utilite Pro is a miniature fanless desktop pc based on
the i.MX6 Quad powered cm-fx6 module. It features two serial ports,
USB OTG, 4x USB, analog audio and S/PDIF, 2x Gb Ethernet, HDMI and
DVI ports, an on-board 32GB SSD, a mmc slot, and on-board wifi/bt.
Add initial support for it including USB, Ethernet (both ports), sata
and HDMI support.
