[PATCH v6 05/11] drm/mediatek: dp: Move AUX_P0 setting to mtk_dp_initialize_aux_settings()
From: AngeloGioacchino Del Regno
Date: Mon Jul 17 2023 - 10:15:14 EST
Move the register write to MTK_DP_AUX_P0_3690 to set the AUX reply mode
to function mtk_dp_initialize_aux_settings(), as this is effectively
part of the DPTX AUX setup sequence.
