[PATCH 0/3] ARM: qcom_defconfig: display related configs.

[srinivas.kandagatla]

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

Hi Andy, 
Here are some Kconfig options that are required to test display on 8064.

Without which we have to manually enable these configs for display testing
based on mainline.

Thanks,
srini

What exactly do you mean by "display"? Which ip block requires IOMMU
support?

display block in apq8064 is mdp4 (drivers/gpu/drm/msm/mdp/mdp4)..
technically it can use iommu in bypass mode w/ physically contiguous
memory, but no one wants to do that, if they don't have to.  The gpu
does have a hard requirement on iommu.
