Subject: [PATCH 1/4] ARM: dts: dra7: add entry for bb2d module

From: Gowtham Tammana <[email protected]>

BB2D is a Vivante GC 2D Accelerator.
This adds the node to the dts file within a target module node.
Crossbar index number is used for interrupt mapping.

Yes you're right, I'll resend only this patch with no status property on bb2d node.

If there is no driver loaded, we idle the target-module anyways.
