[PATCH v3 0/5] V3M-Eagle HDMI output enablement

[PATCH v3 0/5] V3M-Eagle HDMI output enablement

[Jacopo Mondi]

Hello,
   I have rebased the Eagle display enablement on top of (part of) Sergei's
series:
 [PATCH v2 0/5] Add R8A77970/V3MSK LVDS/HDMI support

Simon: you can skip "[1/5]  arm64: dts: renesas: r8a77970: add FCPVD support"
as you already collected that

Sergei: I re-sent your series because there was an additional comment from
Laurent on [3/5]. I felt it was wrong to send a follow up patch on a series
still not collected by Simon, so I've resent it. Hope this time is ok with you.
Also, please note that [5/5] of your original series shall be re-sent using
the newly introduced (still in-review) LVDS decoder. Please see [5/5] of this
series as an example.

Niklas: [5/5] of this series is a fixup of your patches and mine. I added
your signed-off-by, hope it is ok.

The series depends on THC63LVD1024 driver, currently submitted for inclusion
"[PATCH v8 0/2]  drm: Add Thine THC63LVD1024 LVDS decoder bridge"
currently available at:
git://jmondi.org/linux lvds-bridge/linus-master/v8

Thanks
   j

v2 -> v3:
- Use Sergei's series for patches [1-4] with a minor comment from Laurent
- Remove the lvds-decoder node label and add Laurent's Reviewed-by in [5/5]

v1 -> v2:
- Add Laurent's reviewed by tags
- Fixup patch 5, 6 and 7 of v1
- Remove DU digital output pin muxing
- Update thc63lvd1024 to use the new bindings with mandatory power supply
- Minor fixes (changes are described individually in each patch)

[PATCH v3 5/5] arm64: dts: renesas: eagle: Enable HDMI output

[Jacopo Mondi]

Enable HDMI output on Renesas R-Car V3M Eagle board.

The HDMI ouput is enabled connecting the DU LVDS output to the
transparent LVDS converter THC63LVD1024, and successively routing its
RGB output to the ADV7511W HDMI encoder.

v1 -> v2:
- Squash patches [5/7], [6/7] and [7/7] of v1 in a single patch as
  suggested by Laurent
- Remove DU pinmuxing as it is used for DU parallel RGB output only used
  by Eagle's display expander board not enabled by this series.
