[PATCH v12 04/14] drm/msm/disp/dpu: reset the datapath after timing engine disable

From: Vinod Polimera
Date: Mon Jan 30 2023 - 10:12:34 EST


Reset the datapath after disabling the timing gen, such that
it can start on a clean slate when the intf is enabled back.
This was a recommended sequence from the DPU HW programming guide.
