After calling mxs_dma_disable_chan() for a channel, that channel
becomes unusable because some controller registers can only be written
when the clock is enabled via CLKGATE.

... I do not remember any special reason to call mxs_dma_reset_chan()
here when I wrote the code. Now I start guessing it's not necessary.

Hi,
I'm resending two bugfixes for the mxs-dma driver, that I had
originally sent in April which were acked by Shawn Guo and Uwe
Kleine-König, but obviously were not picked up by any maintainer.
Best regards,
Lothar Waßmann

Sorry about that, in case you received ack on same patch you can carry
them when you resend.
Shawn, Uwe Kleine-König pls send your acks again, I will apply these
