amba pl011: platform data for reg lockup and glitch v2
This patch provides platform data for following
- uart reset function to assist uart register lockup workaround
- init/exit function to fix glitch in the tx pin in tty_open
when tty port0 is opened a glitch is seen in the tx line
of uart0. 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.
