The FEC driver ignores the GPIO polarity from 'phy-reset-gpios' and
considers that the Ethernet PHY is active low, unless the
property 'phy-reset-active-high' is present.
Fix the device tree description by explicitly passing the
'GPIO_ACTIVE_LOW' flag to the 'phy-reset-gpios' property.

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.

As of commit 182cdcb8bb ("serial: mxs-auart: Use generic
uart-has-rtscts DT property"), the Freescale MXS AUART driver recognizes
the generic "uart-has-rtscts" DT property, deprecating the
vendor-specific "fsl,uart-has-rtscts" DT property. Hence replace the
latter by the former in all DTS files.

Commit 78b81f4666 ("ARM: dts: imx28-evk: Run I2C0 at 400kHz") caused issues
when doing the following sequence in loop:
- Boot the kernel
- Perform audio playback
- Reboot the system via 'reboot' command
In many times the audio card cannot be probed, which causes playback to fail.
After restoring to the original i2c0 frequency of 100kHz there is no such
problem anymore.
This reverts commit 78b81f4666.

Most of this branch consists of updates, additions and general churn of
the device tree source files in the kernel (arch/arm/boot/dts). Besides
that, there are a few things to point out:
- Lots of platform conversion on OMAP2+, with removal of old board files
for various platforms.
- Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well
- Some updates to pinctrl and other subsystems. Most of these are for
DT-enablement of the various platforms and acks have been collected.

been MX28_PAD_SSP2_SS0__GPIO_2_19, while the given value 0x2131
represents: MX28_PAD_SSP2_SS0__AUART3_TX

Instead of using a custom binding for retrieving the GPIO that activates the
LCD from devicetree, use a standard regulator.
This approach has the advantage to be more generic.
For example: in the case of a board that has a PMIC supplying the LCD voltage,
the current approach would not work, as it only searches for a GPIO pin.
