[PATCH v3 0/7] drm/sysfb: simpledrm: Various improvements

[Thomas Zimmermann <tzimmermann@suse.de>]

Patches 1 to 5 improve validation of the values provided by the
device firmware.

Patches 6 and 7 improve support for panel orientation. There's a rotation
property in the DT panel node. Read the value and set the connector's
orientation property accordingly. To do so, patch 6 moves the existing
code for parsing the rotation to drm_of.c. This makes it available to
simpledrm without introducing a dependency on DRM_PANEL.

v3:
- use shared helper for parsing the panel orentation (Thierry)
- fix framebuffer size checks (Sashiko)
- minor improvements
v2:
- further improve input validation (Sashiko)
