Delete branch "gpio-function-set-masked"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Similar to gpio_init_mask, gpio_set_function_mask allows setting multiple GPIO functions with one call.
LGTM
...although unlike the other
_maskedfunctions, this works by iterating over the GPIOs in a loop, rather than doing a single register-write. I dunno if this is an important-enough distinction to be worth noting in the Doxygen-comment?
