37d7b7a5ba ARM: dts: imx6dl-yapp4: Add support for OLED based on different controller 
OLED display consist of an OLED panel and a display controller.
The displays that were used on yapp4 platform were based on a SSD1305
controller. These displays are now discontinued and we need to add
support for a replacement.

The new display is based on SSD1309 controller and requires slightly
different configuration (mirror + segment offset).  We want to support
both display types so it does no matter which one was used on the assembly
line. Hence the displays are placed at different I2C addresses.

452831f315 ARM: dts: imx6dl-yapp4: Enable the I2C3 bus on all board variants 
imx6dl-yapp4 Draco and Ursa boards use the I2C3 bus to control some
external devices through the /dev files.

So enable the I2C3 bus on all board variants, not just on Hydra.

764b5b5e70 ARM: dts: imx6dl-yapp4: Enable the MPR121 touchkey controller on Hydra 
Add the touch keyboard present on Hydra board. The controller
is connected only using I2C lines. The interrupt line is not
available hence we use the polling mode.
