[PATCH 1/8] ARM: dts: am335x-sl50: update backlight nodes

[Enric Balletbo i Serra]

This patch updates the backlight nodes to improve the support and describe
better how hardware is done. The changes done were:

 * Use PWM_POLARITY_INVERTED instead of the hardcoded number.
 * Add pinctrl configuration.
 * Add the enable gpio definition.
 * Add the power supply definition.
 * Add more brightness levels.

[PATCH 2/8] ARM: dts: am335x-sl50: use phy-phandle declarations

[Enric Balletbo i Serra]

phy-phandle is now a preferred method to reference a PHY device. The new
method also allows you to specify a reset gpio which is required for
this board.

[PATCH 3/8] ARM: dts: am335x-sl50: add a node for the LCD controller

[Enric Balletbo i Serra]

Add the pins used by the LCD controller, the panel-info and display-timings
information for the MIDAS displays connected to the board. There are
two displays in the board, and these, are connected to the LCD controller
through a FPGA, so the timings and the resolution is what expects the FPGA,
not the MIDAS displays.

[PATCH 7/8] ARM: dts: am335x-sl50: fix label names for all LEDs.

[Enric Balletbo i Serra]

Fix the label for all LEDs, we made a mistake setting the label names on
all LEDs, where says green should say red, and viceversa, where says red
should be green.

[PATCH 8/8] ARM: dts: am335x-sl50: enable tsadc on SL50 board.

[Enric Balletbo i Serra]

The tsadc is used to read various voltages on the board, so enable it
to be able to read these voltages from userspace.
