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 bfdc56e54890fd6be05f14c9441c540e649468f7 Mon Sep 17 00:00:00 2001 From: Ryder Lee Date: Wed, 25 Apr 2018 12:19:57 +0800 Subject: [PATCH] ASoC: mediatek: add MT7622 AFE support This patch adds support for the MT7622 AFE which reuses MT2701 driver. We also introduce the 'struct mt2701_soc_variants' to differentiate between the SoC generations as there might be other (existing or future) chips that use the same binding and driver, then being a little more abstract could help in the long run.
