* ARM: ux500: switch to using pinctrl for uart0Linus Walleij2012-05-111-0/+19
| | | | | | | | | | UART0 had a hack that enabled its pins on init and put it to sleep on the exit callback. Replace this with the pinctrl calls to do the same thing and update the runtime table with the two apropriate states for runtime/active and idle.

This happens in pl011_startup() when tx fifo interrupt is provoked into asserting. Now uart0 pins are enabled (alt function) only when init is complete and turned back to gpio when closed.
