Re: [RFC 1/6] drm/etnaviv: add binding for the gc320 found in ti socs

Sorry, messed up the cover-header, patches 3 & 4 in this series where
cherry picked form ti's v4.4.x tree:

http://git.ti.com/cgit/cgit.cgi/ti-linux-kernel/ti-linux-kernel.git/commit/arch/arm/boot/dts/dra7.dtsi?h=ti-linux-4.4.y&id=8067f5a5619ce45657d3729ab3adb9e5b1294f0d

http://git.ti.com/cgit/cgit.cgi/ti-linux-kernel/ti-linux-kernel.git/commit/Documentation/devicetree/bindings/gpu/ti-bb2d.txt?h=ti-linux-4.4.y&id=ddadad0828f8e5ad7e89b11dd243249228ff2997

"ti,gc320-gpu-subsystem" seems like the best middle ground option, the
gc320 is found on one omap4770, omap5, dra7..

"ti,omap-gpu-subsystem" might clash with the naming for the sgx544 3D
core found on these devices, then some day, ti could use
"ti,sgx<num>-gpu-subsystem"

For BeagleBoard.org & BeagleBoard-x15 users we have this working in
the updated images.

For people looking to build the packages, i have it up here:
