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 8d9e4c9e993f34e7f74bf36f417920a01a42c4b0 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Thu, 3 Nov 2016 15:55:48 +0800 Subject: [PATCH] ASoC: sun4i-codec: Add support for A31 playback through headphone output The A31 has a similar codec to the A10/A20. The PCM parts are very similar, with different register offsets. The analog paths are very different. There are more inputs and outputs. The ADC mux has been replaced with a proper mixer. This patch adds support for the basic playback path of the A31 codec, from the DAC to the headphones. Headphone detection, microphone, signaling, other inputs/outputs and capture will be added later.
