ASoC: Intel: bytcr_wm5102: add various quirks
Merge series from Hans de Goede <hdegoede@redhat.com>: Hi Mark, As requested here is a v2 of my series to add various quirks to the bytcr_wm5102 Intel board driver to make it more flexible. Changes in v2: - Dropped 2 already merged patches - Rebased on top of broonie/sound/for-6.7 Regards, Hans Hans de Goede (4): ASoC: Intel: bytcr_wm5102: Add BYT_WM5102_SSP2 quirk ASoC: Intel: bytcr_wm5102: Add BYT_WM5102_MCLK_19_2MHZ quirk ASoC: Intel: bytcr_wm5102: Add BYT_WM5102_OUT_MAP quirk ASoC: Intel: bytcr_wm5102: Add BYT_WM5102_IN_MAP quirk sound/soc/intel/boards/bytcr_wm5102.c | 229 +++++++++++++++++++++++--- 1 file changed, 202 insertions(+), 27 deletions(-) -- 2.41.0
