* soc: Convert to using %pOF instead of full_nameRob Herring2017-08-161-2/+2
| | | | | | | | | | | | | | | | | | Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

| | | | | | | | | | | | | | of_mm_gpiochip_add_data() calls mm_gc->save_regs() before setting the data.

* powerpc: qe_lib-gpio: use gpiochip data pointerLinus Walleij2016-03-301-12/+8
| | | | | | | | | | | | This makes the driver use the data pointer added to the gpio_chip to store a pointer to the state container instead of relying on container_of().

* powerpc: qe_lib/gpio: Be sure to clamp return valueLinus Walleij2016-01-251-1/+1
| | | | | | | | | | | | | As we want gpio_chip .get() calls to be able to return negative error codes and propagate to drivers, we need to go over all drivers and make sure their return values are clamped to [0,1]. We do this by using the ret = !!(val) design pattern.
