Subject: [PATCH] ASoC: bdw-rt5677: Turn on MCLK1 for DSP via DAPM
Git-commit: 55229597a94531726878229ccfcd3fe4ec572dc3
Patch-mainline: v5.5-rc1
References: jsc#SLE-16518
The RT5677 DSP needs the I2S MCLK1 to run its DSP. Add a dapm route to
SSP0 CODEC IN so the clock is turned on automatically when the DSP is
turned on.
