The patch ASoC: meson: axg-toddr: add g12a support
has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 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. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From a3c23a8ad4dc07100d916d75ca30c982288b868d Mon Sep 17 00:00:00 2001 From: Jerome Brunet <jbru...@baylibre.com> Date: Thu, 4 Apr 2019 13:17:30 +0200 Subject: [PATCH] ASoC: meson: axg-toddr: add g12a support Since the g12a SoC fifo can set the fifo initial start address, we must make sure to actually reset the write pointer to this address when starting a capture.
