Message

I'm reviving Sean Paul's old patchset to get mode support in device
tree.  The cover letter for his v3 is at:
https://lists.freedesktop.org/archives/dri-devel/2018-February/165162.html

I've pulled together the patches that didn't land in v3, addressed
outstanding feedback, and reposted.  Atop them I've added patches for
rk3288-veyron-jerry and rk3288-veryon-minnie.

Please let me know how they look.

In general I have added people to the whole series who I think would
like the whole series and then let get_maintainer pick extra people it
thinks are relevant to each individual patch.  If I see you respond to
any of the patches in the series, though, I'll add you to the whole
series Cc list next time.

Changes in v4:
- Simplify desc. for when override should be used (Thierry/Laurent)
- Removed Rob H review since it's been a year and wording changed
- Don't add mode from timing if override was specified (Thierry)
- Add warning if timing and fixed mode was specified (Thierry)
- Don't add fixed mode if timing was specified (Thierry)
- Refactor/rename a bit to avoid extra indentation from "if" tests
- i should be unsigned (Thierry)
- Add annoying WARN_ONs for some cases (Thierry)
- Simplify 'No display_timing found' handling (Thierry)
- Rename to panel_simple_parse_override_mode() (Thierry)
- Rebase to top of Heiko's tree
- Converted changelog to after-the-cut for non-DRM change.
- display_timing for Innolux n116bge new for v4.
- display_timing for AUO b101ean01 new for v4.
- rk3288-veyron-jerry patch new for v4.
- rk3288-veyron-minnie patch new for v4.

Changes in v3:
- Go back to using the timing subnode directly, but rename to
  panel-timing (Rob)
- No longer parse display-timings subnode, use panel-timing (Rob)
- Unwrap the timing from display-timings and rename panel-timing (Rob)

Changes in v2:
- Split out the binding into a new patch (Rob)
- display-timings is a new section (Rob)
- Use the full display-timings subnode instead of picking the timing
  out (Rob/Thierry)
- Parse the full display-timings node (using the native-mode) (Rob)
- Wrap the timing in display-timings node to match binding (Rob/Thierry)
