So far driver model's GPIO uclass just implements the existing GPIO API.
This has some limitations:
- it requires manual device tree munging to support GPIOs in device tree
(fdtdec_get_gpio() and friends)
- it does not understand polarity
- it is somewhat slower since we must scan for the GPIO device each time
- Global GPIO numbering can change if other GPIO drivers are probed
- it requires extra steps to set the GPIO direction and value
The new functions have a dm_ prefix where necessary to avoid name conflicts
but we can remove that when it is no-longer needed. The new struct gpio_desc
holds all required information about the GPIO. For now this is intended to
be stored by the client requesting the GPIO, but in future it might be

Current MIPS systems do not require that loads be performed to force the
parity of cache lines, a simple invalidate by clearing the tag for each

invalidation conditional upon the CONFIG_SYS_MIPS_CACHE_INIT_RAM_LOAD
option, and defines that for existing mips32 targets. Exceptions are
malta where this is known to be unnecessary, and qemu-mips where caches
