X-Git-Tag: v5.10.7~1331^2~131^2~182 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=41d5d7b330b0a7b9b24aa7bfc61fdc9cfb64d27a;p=platform%2Fkernel%2Flinux-rpi.git Merge series "Support headset on Tegra boards that use WM8903" from Dmitry Osipenko : Hello, Some devices have a 4-pin jack instead of a 3-pin and currently the WM8903 configuration is hardcoded to the case of 3-pin jack in the Tegra's ASoC driver. A new device-tree property is required in order to convey that hardware has a 4-pin jack, and thus, microphone's detection needs to be done in a different way. In particular this is needed for Acer A500 tablet device that has a 4-pin headset jack, otherwise userspace sees headset instead of headphones and internal microphone isn't enabled by ALSA UCM rule when it should be. Please review and apply, thanks in advance.
