Changes in V3:
1. Add the corresponding head files for GENMASK and FIELD_PREP to
avoid build break.
2. Remove the patch 2 and patch 3 in the original patch set, as the
loopback and RTS/CTS flags may not need to be cleared in .shutdown().
---

The patchset improve the Idle Line Interrupt for lpuart driver, also handle
the registers correctly for lpuart32 when closing the uart port.

Patches have been tested on imx8ulp-evk platform.

Sherry Sun (3):
  tty: serial: fsl_lpuart: only enable Idle Line Interrupt for non-dma
    case
  tty: serial: fsl_lpuart: disable Rx/Tx DMA in lpuart32_shutdown()
  tty: serial: fsl_lpuart: clear LPUART Status Register in
    lpuart32_shutdown()
