[PATCH 0/5] drm/tegra: fbdev: Use client buffers

[Thomas Zimmermann <tzimmermann@suse.de>]

A client buffer holds the DRM framebuffer for an in-kernel DRM
client. Until now, tegra created an internal ad-hoc framebuffer for
its fbdev emulation, while by-passing the regular interfaces used by
user-space compositors.

Convert tegra's fbdev emulation to use client buffers. Replacing the
existing code with a client buffer allows for stream-lining tegra code
and later also the fbdev helpers. The new framebuffer will be registered
against the client's file and will support handles for GEM objects. It
is then just another framebuffer within the DRM ecosystem.

Patches 1 and 2 fix problems in the fbdev-emulation code.

Patches 3 and 4 convert fbdev emulation to shared DRM interfaces and
client buffers.

Patch 5 cleans up.

Thomas Zimmermann (5):
  drm/tegra: fbdev: Do not assign to struct drm_fb_helper.info
  drm/tegra: fbdev: Remove offset into framebuffer memory
  drm/tegra: fbdev: Calculate buffer geometry with format helpers
  drm/tegra: fbdev: Use a DRM client buffer
  drm/tegra: Make tegra_fb_alloc() an internal interface
