The sof-rt5682 machine driver currently uses BCLK on BYT/Minnowboard
platform. The MCLK signal is available since the Turbot revision, so
enable MCLK on BYT/Minnowboard Turbot platform.
The commit message is not wrong but for more context the MCLK is enabled
on all known BYT/CHT platforms except early MinnowBoards and Up where
the MCLK is not available on the low-speed/HAT connector.

if (sof_rt5682_quirk & SOF_RT5682_MCLK_EN) {
+ if (sof_rt5682_quirk & SOF_RT5682_MCLK_BYTCHT_EN) {
+ ret = clk_prepare_enable(ctx->mclk);
+ if (ret < 0) {
+ dev_err(rtd->dev,
+ "could not configure MCLK state");
+ return ret;
+ }
+ }
Note that we could technically fallback to using the BCLK only in the
error case but it's an unlikely scenario which we've never seen, so
Patch 1 and 2
