The Imagination PVR/SGX GPU is part of several SoC from multiple vendors, e.g. TI OMAP, Ingenic JZ4780, Intel Poulsbo, Allwinner A83 and others.
With this binding, we describe how the SGX processor is interfaced to the SoC (registers and interrupt).
The interface also consists of clocks, reset, power but information from data sheets is vague and some SoC integrators (TI) deciced to use a PRCM wrapper (ti,sysc) which does all clock, reset and power-management through registers outside of the sgx register block.
Therefore all these properties are optional.
