Subject: ASoC: omap-abe-twl6040: Use provided MCLK frequency from pdata
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=62ba98ce4a74ef606e6a7f6c8541fc5e3127f944;p=openwrt%2Fstaging%2Fblogic.git

ASoC: omap-abe-twl6040: Use provided MCLK frequency from pdata

Avoid using hardwired configuration for MCLK frequency.
Different board design might use other MCLK frequency.
