The LG Optimus Black (P970) codename sniper is a smartphone that was designed
and manufactured by LG Electronics (LGE) and released back in 2011.
It is using an OMAP3630 SoC, GP version.

This adds devicetree support for the device, with only a few basic features
supported, such as debug uart, i2c, internal emmc and external mmc.

Cool :)

Care to try to narrow down exactly which GPIO(s) need to be preserved?
Chances are this will unnecessarily block deeper idle states in hardware
otherwise.

My guess is that the GPIO pins that need to be preserved if any are in
the GPIO bank 1 as that's always powered..

Regards,

Tony

Could you please use the IOPAD mux macros from
include/dt-bindings/pinctrl/omap.h instead?

We just did a massive cleanup on the OMAP DTS to use them instead of
an offset from the padconf registers.

Best regards,
Javier

Well, I actually need to keep the GPIOs handling backlight control,
buttons LEDs and the micro USB connector muxing (which can be set to
UART or USB). Those are spread accross gpio2, gpio5 and gpio6, so I'll
only enable these in v2.

Thanks for the review!

Sure thing, will do in v2.

Thanks for the review!
