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. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 6f49919d11690a9b5614445ba30fde18083fdd63 Mon Sep 17 00:00:00 2001 From: Tzung-Bi Shih Date: Fri, 22 Nov 2019 15:31:13 +0800 Subject: [PATCH] ASoC: max98090: exit workaround earlier if PLL is locked According to the datasheet, PLL lock time typically takes 2 msec and at most takes 7 msec. Check the lock status every 1 msec and exit the workaround if PLL is locked.
