[PATCH V2 0/2] tty: serial: imx: improve the imx uart wakeup function

[Sherry Sun]

Make some improvements for imx uart wakeup function. The first patch adds
device_may_wakeup() check before configuring the wake related registers.
The second patch adds the wakeup event reporting support for imx uart.

Changes in V2:
1. Improve the commit message as Peng suggested.
2. Initialize the may_wake and wake_active variables to avoid build
   warnings. 
3. Move may_wake and wake_active above u32 ucr3.
4. Use linux/irq.h instead of asm/irq.h to avoid build errors.

Sherry Sun (2):
  tty: serial: imx: Only configure the wake register when device is set
    as wakeup source
  tty: serial: imx: Add missing wakeup event reporting
