We are moving to device tree support on OMAP3, but that currently
breaks ADP1653 driver. This adds device tree support, plus required
documentation.

Signed-off-by: Pavel Machek <redacted>

Please be sure to check your patch with checkpatch. There are several
issues on it:

WARNING: DT compatible string "adi,adp1653" appears un-documented -- check ./Documentation/devicetree/bindings/
#78: FILE: arch/arm/boot/dts/omap3-n900.dts:572:
+		compatible = "adi,adp1653";

Hmm. Take a look at part quoted below. Someone needs to fix
checkpatch. Ccing authors.

ERROR: trailing whitespace
WARNING: line over 80 characters

Will fix.

ERROR: trailing statements should be on next line
#177: FILE: drivers/media/i2c/adp1653.c:454:
+	if (!child) return -EINVAL;

I actually did these on purporse... the function is trivial, and by
keeping returns on one line it fits into screen. I see you want it
fixed below, so I'll do that for next version.

+Required Properties:
+
+  - compatible: Must contain one of the following

+
+  - reg: I2C slave address
+
+  - gpios: References to the GPIO that controls the power for the chip.
+
+There are two led outputs available - flash and indicator. One led is
