IT8XXX2 uses shared ns16550.c driver which does not
|
|
provide a power management callback, so create driver
|
|
to handle IT8XXX2 specific UART features. In addition
|
|
to use pm_action_cb, we also need to make some setting
|
|
at uart_it8xxx2_init.

Initialization priority for the UART wrapper driver on ITE IT8XXX2,
|
|
must be set to a lower priority than the matching ns16550 device
|
|
(CONFIG_SERIAL_INIT_PRIORITY).
