Subject: [PATCH_V2 4/4] sound: jz4740: set i2s clk rate to 12MHz
Date: Mon, 26 Jan 2015 13:15:38 +0000 [thread overview]
Message-ID: <1422278138-51097-5-git-send-email-Zubair.Kakakhel@imgtec.com> (raw)
In-Reply-To: <1422278138-51097-1-git-send-email-Zubair.Kakakhel@imgtec.com>
i2s clock rate is not set to 12MHz currently. Set it before enabling
the clock.
Signed-off-by: Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com>

V2 changes: Removed clk_prepare_enable call as clock was already being
enabled elsewhere. Just set rate to 12MHz.
