b86d3d21cd ARM: dts: imx6dl-yapp4: Add reg property to the lp5562 channel node
Add the reg property to each channel node.  This update is
to accommodate the multicolor framework.  In addition to the
accommodation this allows the LEDs to be placed on any channel
and allow designs to skip channels as opposed to requiring
sequential order.

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.

e42fb04e98 ARM: dts: imx6dl-yapp4: Add ethernet aliases
Add aliases for ethernet switch ports to allow bootloader to fix
MAC addresses to the ones stored in onboard configuration EEPROM.

Ursa has only one ethernet port populated (eth2) so alias for
the first port has to be removed on this board.

fa28d8212e ARM: dts: imx: default to #pwm-cells = <3> in the SoC dtsi files
The imx-pwm driver supports 3 cells and this is the more flexible setting.
So use it by default and overwrite it back to two for the files that
reference the PWMs with just 2 cells to minimize changes.

This allows to drop explicit setting to 3 cells for the boards that already
depend on this. The boards that are now using 2 cells explicitly can be
converted to 3 individually.

21437391a5 ARM: dts: imx6dl-yapp4: Specify USB overcurrent protection polarity
After reset the oc protection polarity is set to active high on imx6.
If the polarity is not specified in device tree it is not changed.

The imx6dl-yapp4 platform uses an active-low oc signal so explicitly
configure that in the device tree.

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.

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.

1a7ee0efb2 ARM: dts: imx6dl-yapp4: Use rgmii-id phy mode on the cpu port
Use rgmii-id phy mode for the CPU port (MAC0) of the QCA8334 switch
to add delays to both Tx and Rx clock.

It worked with the rgmii mode before because the qca8k driver
(incorrectly) enabled delays in that mode and rgmii-id was not
implemented at all.

Commit 5ecdd77c61 ("net: dsa: qca8k: disable delay for RGMII mode")
removed the delays from the RGMII mode and hence broke the networking.

To fix the problem, commit a968b5e9d5 ("net: dsa: qca8k: Enable delay
for RGMII_ID mode") was introduced.

Now the correct phy mode is available so use it.
