[PATCH 0/4] ARM: dts: dra7: enable BB2D module

[Neil Armstrong]

The DRA7 & variant SoCs contains a BB2D module which is a Vivante GC320 2D accelerator.

This patchset adds the GPU node and enables it on the DRA7, DRA72 & AM57xx platforms.

This is a follow-up of [1] & [2] but:
- using the vivante,gc bindings only
- using ti,sysc instead of hwmod

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

[Neil Armstrong]

From: Gowtham Tammana <g-tammana@ti.com>

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.

How about just use the default for the bb2d node with is "okay"?
That way there's no need set status = "okay" for each board file.

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

Tony

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