[PATCH v3 0/6] LPUART fixes and improvements

[Andrey Smirnov]

Everyone:

This series contains fixes/improvements to LPUART dirver I came up
with recently as well as fixes picked up from Toradex and NXP Vybrid
repos.

Feedback is welcome!

Changes since [v2]:

 - Series rebased on Greg's tty-testing branch

Changes since [v1]:

 - Dropped "tty: serial: fsl_lpuart: Drop unnecessary sg_set_buf()
   call" due to being a duplicate of "tty: serial: fsl_lpuart: remove
   sg_set_buf() for sport->rx_sgl"
   
 - Fixed build break in "tty: serial: fsl_lpuart: Introduce
   lpuart_tx_dma_startup()"

Thanks,
Andrey Smirnov
