[alsa-devel] [PATCH v3 16/18] ASoC: fsl-ssi: Set framerate divider correctly for i2s master mode

[Markus Pargmann]

From: Sascha Hauer <s.hauer at pengutronix.de>

In i2s master mode the fsl_ssi driver depends on someone calling
.set_tdm_slot correctly. In this mode though only a DC value of
2 is allowed, so set it in this case and no longer depend on
.set_tdm_slot.
