This a series of patches is a DRM Driver for Rockchip Socs, add support for vop devices. Future patches will add additional encoders/connectors, such as eDP, HDMI.
The basic "crtc" for rockchip is a "VOP" - Video Output Processor. the vop devices found on Rockchip rk3288 Soc, rk3288 soc have two similar Vop devices. Vop devices support iommu mapping, we use dma-mapping API with ARM_DMA_USE_IOMMU.
[...]
Changes in v15:
- remove depends on ARM_DMA_USE_IOMMU & IOMMU_API which cause recursive dependency problem
I thought the recommended solution for this was to fix OMAP3 to not select ARM_DMA_USE_IOMMU and OMAP_IOMMU, not to drop the 'depends on' in drm/rockchip?
Lets fix that up once we get this merged, if I had a tree based on the iommu I'd have it -next now.
can I get a pull for that? Dave.
