[RFC PATCH] drm/imx: ipuv3-plane: Allow preventing sequential DMA bursts

2023-10-27 Thread Miquel Raynal
Sequential DMA bursts improve NIC/RAM usage thanks to the basic NIC hardware optimizations available when performing in-order sequential accesses. This can be further enforced with the IPU DMA locking mechanism which basically prevents any other IP to access the interconnect for a longer time
