drm/i915/dsi: Fix swapping of MIPI_SEQ_DEASSERT_RESET / MIPI_SEQ_ASSERT_RESET

2016-12-20T14:28:25Z

Looking at the ADF code from the Android kernel sources for a cherrytrail tablet I noticed that it is calling the MIPI_SEQ_ASSERT_RESET sequence from the panel prepare hook. Until commit b1cb1bd29189 ("drm/i915/dsi: update reset and power sequences in panel prepare/unprepare hooks") the mainline i915 code was doing the same. That commits effectively swaps the calling of MIPI_SEQ_ASSERT_RESET / MIPI_SEQ_DEASSERT_RESET. Looking at the naming of the sequences that is the right thing to do, but the problem is, that the old mainline code and the ADF code was actually calling the right sequence (tested on a cube iwork8 air tablet), and the swapping of the calling breaks things. This breakage was likely not noticed in testing because on cherrytrail, currently chv_exec_gpio ends up disabling the gpio pins rather then setting them (this is fixed in the next patch in this patch-set). This commit fixes the swapping by fixing MIPI_SEQ_ASSERT/DEASSERT_RESET's places in the enum defining them, so that their (new) names match their actual use. Changes in v2: -Add a comment to the enum explaining that the assert/reassert names are swapped in the spec Fixes: b1cb1bd29189 ("drm/i915/dsi: update reset and power sequences...")

drm/i915: hide away VBT private data in a separate header

2016-03-17T09:58:57Z

We've been accumulating code across the driver that depends on the VBT specific structures and defines. The VBT is an uncontrollable beast. Encourage encapsulation of the VBT data by hiding the structures and defines in a private header only to be included from intel_bios.c.
