ASoC: wm8804: Enable runtime PM
Currently both the oscillator and the PLL are powered up in set_bias_level. This can be problematic when using output clocks from the wm8804 for other devices. The snd_soc_codec_set_pll API defines that a clock should be available once the call returns, however, with all the clocking controlled in set_bias_level this is not currently the case. This patch enables pm_runtime for the wm8804, enabling both the regulators and the oscillator when the chip resumes, and enabling the PLL in the snd_soc_codec_set_pll call. Naturally the enabling the PLL will also cause the chip to resume. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>
