Might want to point at the source of the patch -> just for the record,
this came from TI vendor kernel..

+* Texas Instruments BB2D blitter module
+
+This binding describes the 2D BitBlit (BB2D) graphics accelerator
+subsystem based on the GC320 core from Vivante Corporation available
+in Texas Instruments SoCs.
+
+Required properties:
+ - compatible: value should take the following format:
+ "ti,<soc>-bb2d", "vivante,<gpuversion>"
+ accepted values:
+ (a) "ti,dra7-bb2d", "vivante,gc320" for TI DRA7xx / AM57x
+
+ - reg : base address and length of BB2D IP registers
+ - interrupts : BB2D interrupt line number
+ - ti,hwmods : name of the hwmod associated with BB2D module
+ - clocks : handle to BB2D functional clock
+ - clock-names : fclk
+
+Example for DRA7x SoC:
+ bb2d: bb2d@59000000 {
+ compatible = "ti,dra7-bb2d", "vivante,gc320";
+ reg = <0x59000000 0x0700>;
+ interrupts = <GIC_SPI 120 IRQ_TYPE_LEVEL_HIGH>;
+ ti,hwmods = "bb2d";
+ clocks = <&dpll_core_h24x2_ck>;
+ clock-names = "fclk";
+ };
