ARM: dts: imx6qdl.dtsi: add "arm,shared-override" for pl310 The imx6 SMP system has the same DMA memory coherency issue [1] with pl310 L2 controller. With this shared override bit set, the customer reports the DMA coherency issue is gone. Besides, I have tested the performance using USB ethernet with/without this bit, it shows no difference.
