[PATCH] pinctrl: Pass all configs to driver on pin_config_set()

On 08/15/2013 04:42 PM, Sherman Yin wrote:

When setting pin configuration in the pinctrl framework, pin_config_set() or
pin_config_group_set() is called in a loop to set one configuration at a time
for the specified pin or group.

This patch 1) removes the loop and 2) changes the API to pass the whole pin
config array to the driver.  It is now up to the driver to loop through the
configs.  This allows the driver to potentially combine configs and reduce the
number of writes to pin config registers.
