config MXC_IPU_V3_PRG tristate "i.MX IPUv3 prefetch gasket engine" depends on MXC_IPU_V3 && MXC_IPU_V3_PRE help This enables support for the IPUv3 prefetch gasket engine to support double buffer handshake control bewteen IPUv3 and prefetch engine(PRE), snoop the AXI interface for display refresh requests to memory and modify the request address to fetch the double buffered row of blocks in OCRAM.

config MXC_IPU_V3_PRE tristate "i.MX IPUv3 prefetch engine" depends on MXC_IPU_V3 select MXC_IPU_V3_PRG help This enables support for the IPUv3 prefetch engine to improve the system memory performance. The engine has the capability to resolve framebuffers in tile pixel format to linear.
