[PATCH 0/3] etnaviv: Add sampler TS support

[Wladimir J. van der Laan]

Sampler TS is an hardware optimization that can be used when rendering
to textures. After rendering to a resource with TS enabled, the
texture unit can use this to bypass lookups to empty tiles. This also
means a resolve-in-place can be avoided to flush the TS.

This patch series adds support for sampler TS on hardware that supports
this. It also contains an optimization when not using sampler TS, as
resolve-in-place will now be skipped if a resource has no (valid) TS.

For example the 'shadow' test in glmark2 increases in performance with:

before: [shadow] <default>: FPS: 130 FrameTime: 7.692 ms
after:  [shadow] <default>: FPS: 244 FrameTime: 4.098 ms
