[PATCH v3 0/6] ARM: qcom: working Nexus 5 display support

[Brian Masney]

This patch series adds working display support to the LG Nexus 5
(hammerhead) phone.

Changes since v2:
- Dropped two drm/msm bug fix patches that have been merged separately.
- New patch: 'add support for per-CRTC max_vblank_count on mdp5'.
  Special thanks to Jeffrey Hugo for helping to track down this issue.
- Add panel_pin to msm8974-hammerhead device tree. Dropped Linus
  Walleij's reviewed-by on this patch due to this change.

Changes since v1:
- Shortened problem description above. I'll reply to this email and send
  a full dmesg with the boot log with debugging turned on.
- Dropped patch 'fix null pointer dereference in
  msm_atomic_prepare_fb()'
- New patch: Remove resv fields from msm_gem_object struct that was
  incorrectly being referenced by the prepare_fb callbacks.
- Add drm_plane_enable_fb_damage_clips() to plane init for mdp4, mdp5,
  and dpu1.
- Add Linus Walleij's reviewed-by to patches 3-6
