From: Clemens Ladisch Date: Mon, 10 Jan 2011 15:14:52 +0000 (+0100) Subject: ALSA: oxygen: simplify model-specific MCLK handling X-Git-Tag: v2.6.38-rc1~7^2~7^2~22 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5b8bf2a54fb13e40519ee846ce27bc8a2d7a7878;p=platform%2Fkernel%2Flinux-exynos.git ALSA: oxygen: simplify model-specific MCLK handling Replace the get_i2s_mclk callback with tables of MCLK values. This simplifies the MCLK-handling code in both the framework and the model- specific drivers.
