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 cef45771c141fdccebe4cb7e0ce79f4687275494 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Tue, 20 Sep 2016 13:52:33 +0100 Subject: [PATCH] ASoC: wm_adsp: Move control cache sync out of preloader As part of the work to download firmware before the audio path is brought up the DSP will be put into a low power state between downloading firmware to the core and starting it running. This will mean that the firmware ALSA controls are not accessible in the hardware during this period of time. To prepare for this change we gate access to the hardware in the ALSA control handlers on the DSP being running rather than simply booted and move the synchronisation of the control caches out of the preloader delayed work and into the main DAPM thread after the DSP will have been brought out of its low power state.
