Hi,ALL
I want to output HD signal(I means 720P) using dm355 vpbe Ycc16 interface.The 
default VPBE resolution is 720x480 or 720x576,so I need to change this 
resolution to be 1280x720,and this will result a problem:I can't allocate 
enough DMA memory in the dm355 vpbe driver.That is I can't allocate DMA memory 
greater than 4M,but If I want use 720P in the vpbe,I need about 6M for one 
window.Is the allocation function dma_alloc_coherent limit(In the 
drivers/video/dm355fb.c vpbe_mem_alloc_max function) the memory to be samller 
than 4M?So what should I do next? 
My sdk version is 1_30_00_40.
Any help will be appreciated!
