The patch
ASoC: rt5677: Reconfigure PLL1 after resume
has been applied to the asoc tree at

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

Sometimes PLL1 stops working if the codec loses power during suspend (when pow-ldo2 or reset gpio is used). MX-7Bh(RT5677_PLL1_CTRL2) is cleared and won't be restored by regcache since it's volatile. MX-7Bh has one status bit and M code for PLL1. rt5677_set_dai_pll doesn't reconfigure PLL1 after resume because it thinks the PLL params are not changed.
This patch clears the cached PLL params at resume so that rt5677_set_dai_pll can reconfigure the PLL after resume.
