On i.MX6 the DMA event for the RX channel of UART6 is '0'. To fix
I would suggest being a bit more specific than saying i.MX6.
I see UART6 is present on i.MX6UL/i.MX6SX, but not on i.MX6Q/i.MX6DL, so it would be better to specify it in the commit log.
imx6ul.dtsi does not have dma nodes under uart6, so I guess you fixed it for imx6sx.
Sounds reasonable. I will change the commit message to refer to i.MX6UL/ULL/SX.
Actually one of our customers has a dts for i.MX6UL, that enables the DMA for UART6. The DMA not being enabled in imx6ul.dtsi doesn't mean no one is using it. Actually I have no idea why it's enabled by default for i.MX6SX and disabled by default for i.MX6UL.
Thanks, Frieder
the broken DMA support for UART6, we change the check for event_id0 to include '0' as a valid id.
