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 dac5f86bc9e60eae87a28512f025362d1e2574e3 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Fri, 25 Nov 2016 20:34:36 +0800 Subject: [PATCH] ASoC: sun4i-codec: Add support for A23 codec The codec in the A23 is similar to the one found on the A31. One key difference is the analog path controls are routed through the PRCM block. This is supported by the sun8i-codec-analog driver, and tied into this codec driver with the audio card's aux_dev. In addition, the A23 does not have LINEOUT, and it does not support headset jack detection or buttons.
