Subject: drm: Add an hx8367d tinydrm driver.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I want to sort out support for tinydrm in vc4, so I needed to get a
tinydrm-appropriate panel working and this is what I had on hand.
This is derived from a combination of ili9341.c from tinydrm and
fb_hx8357d.c from staging's fbtft.

v2: Write my own register defs from the spec to not need the header
    from fbtft.  Fix spi device string to enable module autoloading.
    (Suggestions by Noralf)

Subject: drm/tinydrm: Use DRM_GEM_CMA_VMAP_DRIVER_OPS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The CMA helper now has the functionality to ensure a virtual address on
imported buffer so use that.

While touching all tinydrm drivers, remove the unnecessary inclusion of
drm_fb_helper.h in some drivers.
