Next in thread: Garlic Tseng: "[alsa-devel] [RFC PATCH 2/4] ASoC: mediatek: add documents for mt2701"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Move mt8173 driver to another folder. The software control sequence of mt2701
are very different from that of mt8173, so this patch move mt8173 code to
another folder
