Subject: [PATCH v3 16/18] ASoC: fsl-ssi: Set framerate divider correctly for i2s master mode
Date: Mon, 14 Apr 2014 15:35:46 +0200
Message-ID: <1397482548-28463-17-git-send-email-mpa@pengutronix.de> (raw)
In-Reply-To: <1397482548-28463-1-git-send-email-mpa@pengutronix.de>

From: Sascha Hauer <s.hauer@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.
