Yes, I have listed dependencies of this series in my v1 cover letter:
---------------------------------------------------------------------------
The series is based on Laurent's drm/next/du branch with patches on top for:
- Sergei: Enable PFC, I2c, GPIOs for r8a77970
- Sergei: Add support for r8a77970 in DU and add display device nodes in
r8a77970 DTSI
- Niklas: Connect DU LVDS output to HDMI bridge adv7511w in Eagle DTS
- Sergei: fix video output on R8A77970
A base branch with these patches applied is available at
git://jmondi.org/linux v3m/v4.16-rc3/base
---------------------------------------------------------------------------
My bad I have not reported this in all cover letters (and I have not
reported the full name of the series)
PFC, GPIO and I2c support I have listed as dependencies seems to have
landed in renesas-drivers, while I don't see yet:
Sergei:
[PATCH v2 0/5] Add R8A77970/V3MSK LVDS/HDMI support
whose patches for r8a77970 dtsi are included in yours:
[PATCH v2 0/5] arm64: dts: renesas: r8a77970: enable HDMI output
On top I also have Sergei's/Laurent's:
[PATCH v4] v4l: vsp1: Fix video output on R8A77970

I'll let Simon suggest how he preferes to handle this, if he wants me
to re-submit your series with this patch squashed on top or he prefers
to deal with this himself.

I assume bindings and driver go through DRM and Simon is to pick up
the Eagle changes.

Actually I'm not aware of Gen2 boards with this chip and similar
display pipelines. Can you point me to which one needs to have its
DTS brushed?
Thanks
