The 'dma-coherent' indicates that the hardware IP block can ensure the coherency of the data transferred from/to the IP block. This can avoid the software cache flush/invalid actions, and improve the performance significantly. The PCI IP block of ls2080a has this capability, so adding this feature to improve the PCI performance. Signed-off-by: Liu Gang <redacted>
Applied, thanks.
