OMAP2/3/4: UART: Allow per-UART disabling wakeup for serial ports
This patch causes the OMAP uarts to honor the sysfs power/wakeup file
for IOPAD wakeups. Before the OMAP was always woken up from off mode
on a rs232 signal change. This patch also creates a different
platform device for each serial port so that the wakeup properties can
be control per port.
By default, IOPAD wakeups are enabled for each UART. To disable,
# echo disabled > /sys/devices/platform/serial8250.0/power/wakeup
Where serial8250.0 can be replaced by .1, or .2 to control the other
ports.
