Add mxc_gpu devices for imx35/50/51/53, so external gpu driver module built
for the kernel can work.

Why do we need this? I have never seen a driver for this.

From the subject, I guess it's a patch to declare the device used by the
driver for the AMD z160 gpu found on theses imx SoCs. iirc, this driver by
itself is GPL but relies on closed-source userspace stuff, that's imho why
you didn't see a driver for it. I think you can find it in fsl tree
inside drivers/mxc/ directory.

Correct. It's for z430/z160 GPU. The kernel part of the driver is in
drivers/mxc/amd-gpu/ of freescale kernel source. It can be built as external
kernel module. We don't have plan to upstream it yet.

Thanks
Richard
