Did you test this change with > all devices that are affected by it? I changed the hardware description of the imx25 SSI to match the reference manual. I did test this change on an imx25 board with audio playback. This uses the SSI description I modified. I verified that the driver is actually taking the modified setting into account and that this causes no problems. As of today, this setting is used by the fsl_ssi driver to set the fifo water level for dma requests. Of course, I don't have access to the enitre range of supported imx25 boards and I don't think this is required for submitting patches. Do you have any indication why this patch should not be merged?
