Commit Message

Noralf Trønnes July 22, 2019, 10:43 a.m. UTC 
This moves mipi-dbi to be a core helper with the name drm_mipi_dbi.

Fixup include's in drivers.
Move the docs entry and delete tinydrm.rst.
Delete the last tinydrm todo entry.

v2: Make DRM_MIPI_DBI tristate to enable it being built as a module.

-tinydrm
--------
-
-Tinydrm is the helper driver for really simple fb drivers. The goal is to make
-those drivers as simple as possible, so lots of room for refactoring:
-
-- extract the mipi-dbi helper (well, the non-tinydrm specific parts at
-  least) into a separate helper, like we have for mipi-dsi already. Or follow
-  one of the ideas for having a shared dsi/dbi helper, abstracting away the
-  transport details more.
