It also defines the interrupt number to be used by the SGX driver. There is currently no mainline driver for these GPUs, but a project [1] is ongoing with the goal to get the open-source part as provided by TI/IMG into drivers/staging/pvr. The kernel modules built from this project have successfully demonstrated to work with the DTS definitions from this patch set on AM335x BeagleBone Black and OMAP5 Pyra. They partially works on DM3730 and PandaBoard ES but that is likely a problem in the kernel driver or the (non-free) user-space blobs. There is potential to extend this work to JZ4780 (CI20 board) and BananaPi-M3 (A83) and even some Intel Poulsbo and CedarView devices. [1]: https://github.com/openpvrsgx-devgroup H.
