The cm-fx6 module has an on-board AW-NH387 WiFi/BT module which is
based on Marvell's SD8787 chip and is connected to the usdhc1
controller.
Unfortunately, the chip gets unresponsive if the Bluetooth AMP
(Alternate Mac/Phy) function gets probed but the loaded firmware
doesn't support it. For instance, this is the case for the most
recent firmware in linux-firmware (Version 14.66.35.p52).
Thus, just add the required nodes but leave the usdhc1 node disabled
explicitly. Users who disabled the Bluetooth (AMP) support of their
OS can then conveniently enable WiFi (or even plain Bluetooth) support
with a simple device tree overlay/bootloader configuration.

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 cm-fx6 module has an onboard Wolfson wm8731 codec which is muxed
to the ssi2 controller. Unlike most (all?) supported i.MX6 board/codec
combinations the wm8731 is operated in slave mode and the clock setup
is static.
Add support for it.

Since commit b36581df7e ("spi: imx: Using existing properties for
chipselects") the device tree property 'fsl,spi-num-chipselects' is
unused and it is already marked as obsolete in device tree binding
documentation. Remove the property from the existing DTS files to
avoid its reoccurence on copying.

Several dts files set a bit in the SPEED field for pads

doesn't have an effect and the bit reads as zero.

The current ldo settings of the cm-fx6 do not allow 1.2GHz cpu
frequency. At this frequency the module behaves unstable.
But the imx6q fuse indicates that 1.2GHz operation is possible.
Hence, remove the 1.2GHz operation point in the device tree.

GPLv2-only devicetrees make reuse difficult for software components
licensed under a different license. In particular, the Utilite Pro
devicetree file (which includes imx6q-cm-fx6.dts) is already dual

Hence, relicense imx6q-cm-fx6.dts under GPLv2/X11 dual license.

- 1 HDMI output port
- 2 LVDS LCD ports
- Gigabit Ethernet
- Analog Audio
- CAN
- SATA
- NAND
- PCIE
This patch allows to boot up the module, configures the serial console,
the Ethernet adapter and the heartbeat led.
cm-fx6 is embedded inside the Utilite computer.
