Regmap is able to enable/disable the core clock automatically each time it's going to access the registers. But for DMA cases during playback or recording, it's totally beyong control of regmap. So we have to open the clock manually. Signed-off-by: Nicolin Chen <Guangyu.Chen@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>
