It's best if you provide a series that enables BT offload across the board for ADL, if that's the intended goal.
Hi Pierre,
{ .name = "adl_mx98357_rt5682", .driver_data = (kernel_ulong_t)(SOF_RT5682_MCLK_EN | SOF_RT5682_SSP_CODEC(0) | SOF_SPEAKER_AMP_PRESENT | SOF_RT5682_SSP_AMP(2) | SOF_RT5682_NUM_HDMIDEV(4)), }, The "adl_mx98357_rt5682" is the sound card of the google "Brya" Board project. Because the SSP2 is used for the max98357 amplifier, so SSP2 bt_offload can't be enabled at the drv_name "adl_mx98357_rt5682". (The hardway layout I2S port2 connected to max98357 amplifier)
The other adl projects that enabled the bt_offload feature were designed with ssp1 for amp, ssp2 for bt_offload based on pins definition. { .name = "adl_rt1019_rt5682", .driver_data = (kernel_ulong_t)(SOF_RT5682_MCLK_EN | SOF_RT5682_SSP_CODEC(0) | SOF_SPEAKER_AMP_PRESENT | SOF_RT1019_SPEAKER_AMP_PRESENT | SOF_RT5682_SSP_AMP(1) | SOF_RT5682_NUM_HDMIDEV(4) | SOF_BT_OFFLOAD_SSP(2) | SOF_SSP_BT_OFFLOAD_PRESENT), }, thanks
