Subject: [PATCH 0/8] serial: fsl_lpuart: sysrq, loopback support and fixes

Give fsl_lpuart some love and add break, loopback and sysrq support. While
at it, some errors were noticed, which are also fixed in this series.

The sysrq support was tested on both interrupt driven and DMA based
transfers on the 32bit LPUART.

Michael Walle (8):
  serial: fsl_lpuart: don't modify arbitrary data on lpuart32
  serial: fsl_lpuart: use UARTDATA_MASK macro
  serial: fsl_lpuart: don't restore interrupt state in ISR
  serial: fsl_lpuart: handle break and make sysrq work
  serial: fsl_lpuart: remove RTSCTS handling from get_mctrl()
  serial: fsl_lpuart: remove manual RTSCTS control from 8-bit LPUART
  serial: fsl_lpuart: add loopback support
  serial: fsl_lpuart: disable DMA for console and fix sysrq
