This is a Linuxisum and shouldn't really live in here.
I think it would be better to document them in ../gpio/gpio.txt and
reference that instead.

Device names don't belong in node names.
Just "gpio" will do.

Nit: We *normally* treat these as bullet-points and not place
full-stops on them:
$ git grep "compatible" -- Documentation/devicetree/bindings/ | grep -v "\.$" | wc -l
5227
$ git grep "compatible.*\.$" -- Documentation/devicetree/bindings/ | wc -l
486
... and I *personally* think it's easier to read the document if it's
formatted as follows:
- compatible : Should be "ti,tps65912".
- reg : Slave address or chip select number (I2C / SPI).
- interrupt-parent : The parent interrupt controller.
- interrupts : The interrupt line the device is connected to.
- interrupt-controller : Marks the device node as an interrupt controller.
- #interrupt-cells : The number of cells to describe an IRQ, this should be 2.
The first cell is the IRQ number.
The second cell is the flags, encoded as the trigger masks from
../interrupt-controller/interrupts.txt
... I hope you agree.

Strange, I thought I made a change to this. Well this brings up a question,
how much change can we have before we are supposed to drop Reviewed/Acked-by?

What about for multi-sentence descriptions, we need the middle full-stops, then to not
have one on the end seems kinda odd looking.

Yeah, I did that with the last driver, not sure why I forgot to fix that here, I'll fix this.

There is a mention of GPIO_ACTIVE_HIGH, as it's used in an example.
However GPIO_ACTIVE_LOW is missing. I think both could do with
documenting properly, then you can refer to them from here.

That's the way I usually do it -- doesn't look too bad. ;)

I mean the lines above the example, they say to use the macros
defined in include/dt-bindings/gpio/gpio.h whenever possible,
that's really all I would say.

This patch adds support for TPS65912 PMIC regulators.
The regulators set consists of 4 DCDCs and 10 LDOs. The output
voltages are configurable and are meant to supply power to the
main processor and other components.

This patch adds support for the TPS65912 PMIC GPIOs.
TPS65912 has five configurable GPIOs that can be used for several
purposes.

This looks like a fine driver, can't really see anything wrong with it so:

I would rewrite that to static inline however.
Lee can take this into the MFD tree with my review-tag if he wants.
