Subject: [rft, PATCH v1 0/2] drm/i915/dsi: An attempt to get rid of IOSF GPIO on VLV

DSI code for VBT has a set of ugly GPIO hacks, one of which is direct
talking to GPIO IP behind the actual driver's back. An attempt to fix
that is here.

If I understood correctly, my approach should work in the similar way as
the current IOSF GPIO. 

Hans, I believe you have some devices that use this piece of code,
is it possible to give a test run on (one of) them?
