Javier Martinez Canillas 05e7d622f1 ARM: dts: omap: Add generic compatible string for I2C EEPROM
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.

Javier Martinez Canillas 57a78a8a6f ARM: dts: am335x/am437x: remove unneeded unit name for gpio-keys nodes
This patch fixes the following DTC warnings for many boards:

"Node /gpio_keys/button0@10 has a unit name, but no reg property"

Andrew F. Davis 759bc77b9a ARM: dts: am437x-idk-evm: Mark MAC as having only one PHY
Currently am4372.dtsi declares the MAC controller to have two
slave ports, on this board we only use one, so set the slave
count to one. This eliminates a console error message when
the non-existent PHY is not detected.

Javier Martinez Canillas 8e7d3dd924 ARM: dts: am437x-idk-evm: Use AM4372_IOPAD pinmux macro
Use the pinmux IOPAD macro to define the register absolute physical
address instead of the offset from the padconf base address. This
makes the DTS easier to read since matches the addresses listed in
the Technical Reference Manual.

Mugunthan V N 0731cbdd5f ARM: dts: am43xx: fix cd-gpios definition as per hardware design and dt binding docs
As per mmc device tree binding documentation card detect gpio has
to be active low signal. When a hardware is designed with active
high card detect, gpio polarity has to be changed with
cd-inverted dt property.

In AM43xx the card detect gpio is designed as active low gpio.
So correcting the dt card detect gpio definition.

Felipe Balbi 1236044825 ARM: dts: am437x-idk: fix TPS62362 i2c bus
As it turns out, tps62362 is actually on I2C bus0,
not bus1. This has gone unnoticed because Linux
doesn't use (as of now) that regulator at all, it's
setup by the bootloader and left as is.

While at that, also add missing reg property for
our regulator.

The AM437x Industrial Development Kit (IDK) is
an application development platform targeted at
industrial communication and control applications.

It comes with a 3-phase motor driver, PROFINET,
PROFIBUS and a few other industrial communication
interfaces.

The board has 1GiB of DDR3 RAM, QSPI NOR flash,
a 100% discrete power design (no PMIC) and an
on-board 2MP camera (not supported with Linux
as of this writing).
