Some boards, such as the HiFiBerry DAC+ Pro, use a pair of external oscillators, to generate 44.1 or 48kHz multiples and are forced to resort to hacks[1] in order to support 24-bit data without ending up with fractional dividers. This patch allows the machine driver to use 32-bit frames for 24-bit data to avoid such issues.
This seems fine to me. I think when I accepted the patch for setting bclk ratio that there was hardware which specified the ratio directly as part of the configuration but it seems that this was not the case; on the other hand this seems like a reasonable use for it.
