Subject: EXT: [PATCH 1/1] tty: serial: imx: disable ageing timer interrupt if
dma in use

Since commit 4dec2f119e86 ("imx-serial: RX DMA startup latency")

the interrupt routine no longer will start rx dma.

I think you have 2 commits here: 
- one that disables ageing timer when DMA is in use
- one that cleans the leftovers after 4dec2f119e86.

I agree, Troy, please make a patch series here.

thanks,
