MUTEX will send the EOF trigger signal to all sourcesub-module whose EOF is selected in this register. So I think we should or EOF to make sure sub-module cloud get both SOF and EOF trigger signal for status checking, error handling or debugging. > > +}; > > + > > static const struct mtk_mutex_data mt2701_mutex_driver_data = { > > .mutex_mod = mt2701_mutex_mod, > > .mutex_sof = mt2712_mutex_sof, > > @@ -275,6 +354,13 @@ static const struct mtk_mutex_data > > mt8183_mutex_driver_data = { > > .no_clk = true, > > }; > > > > +static const struct mtk_mutex_data mt8195_mutex_driver_data = { > > + .mutex_mod = mt8195_mutex_mod, > > + .mutex_sof = mt8195_mutex_sof, > > + .mutex_mod_reg = MT8195_DISP_MUTEX0_MOD0, > > + .mutex_sof_reg = MT8195_DISP_MUTEX0_SOF, > > +}; > > + > > struct mtk_mutex *mtk_mutex_get(struct device *dev) > > { > > struct mtk_mutex_ctx *mtx = dev_get_drvdata(dev); > > @@ -347,6 +433,9 @@ void mtk_mutex_add_comp(struct mtk_mutex > > *mutex, > > case DDP_COMPONENT_DPI1: > > sof_id = MUTEX_SOF_DPI1; > > break; > > + case DDP_COMPONENT_DP_INTF0: > > + sof_id = MUTEX_SOF_DP_INTF0; > > + break; > > How about MUTEX_SOF_DP_INTF1? MUTEX_SOF_DP_INTF1 won't use in vdosys0, so it will be added at the patch [1] in vdosys1 series.
