[PATCH v2 0/2] serial: mxs-auart: wait for DMA buffer to flush before shutdown

[Marek Vasut]

Dear Hector Palacios,

> This fixes a bug whereby the AUART was shutdown while bytes
> were still waiting in the DMA buffer to be transmistted.
> 
> Changes since v1:
>  * Split the patch in two: one to set the fifosize to the
>    DMA buffer size, and another to wait for the FIFO to empty
>    before disabling the AUART.
>  * The wait for the fifo to empty is now independent of DMA
>    being enabled.
>  * Fix bug on readl() call
>  * Remove bad URL in commit log
