[PATCH v3.1 00/10] arm64: allwinner: Add A64 DE2 HDMI support

[PATCH v3.1 00/10] arm64: allwinner: Add A64 DE2 HDMI support

[Icenowy Zheng]

Allwinner A64 has display engine pipeline like other Allwinner SOC's A83T/H3/H5.

A64 behaviour similar to Allwinner A83T where
Mixer0 => TCON0 => LVDS/RGB/MIPI-DSI
Mixer1 => TCON1 => HDMI
as per Display System Block Diagram from the A64 user manual.

This is third patch-set followed with previous RFC[1], first and second
series[2][3] and merely concentrated on HDMI pipeline through TCON1 and
rest will add eventually.

I just rebased and slightly re-integrated the patchset according to the
requirments of the maintainer, and added the mixer0->tcon0 pipeline.
The further maintainship of the patchset still needs to be discussed
between I and Jagan.

[PATCH v3.1 01/10] clk: sunxi-ng: a64: Add minimal rate for video PLLs

[Icenowy Zheng]

From: Jagan Teki <jagan-dyjBcgdgk7Pe9wHmmfpqLFaTQe2KTcn/@public.gmane.org>

According to documentation and experience with other similar SoCs, video
PLLs don't work stable if their output frequency is set below 192 MHz.

Because of that, set minimal rate to both A64 video PLLs to 192 MHz.

[PATCH v3.1 02/10] dt-bindings: display: Add compatible for A64 DE2 display pipeline

[Icenowy Zheng]

From: Jagan Teki <jagan-dyjBcgdgk7Pe9wHmmfpqLFaTQe2KTcn/@public.gmane.org>

Allwinner A64 has a DE2 display pipeline. The TCONs are similar to the
ones in A83T, but the mixers are new (similar to the later R40 SoC).

This patch adds dt-binding documentation for A64 DE2 display pipeline.

[PATCH v3.1 07/10] arm64: dts: allwinner: a64: Add display pipeline

Allwinner A64 have a display pipeline with 2 mixers/TCONs, the first
TCON is connected to LCD and the second is to HDMI.

The HDMI controller/PHY pair is similar to the one on H3/H5, but have
two video PLLs selectable.

Add all required device tree nodes of the display pipeline, including
the TCON0 LCD one and the TCON1 HDMI one.

[PATCH v3.1 08/10] dt-bindings: sun4i-drm: add HDMI VCC supply property for sun8i-dw-hdmi

[Icenowy Zheng]

Allwiner SoCs with DesignWare HDMI controller all come with a "HVCC"
pin, which is the VCC of HDMI part.

Add a supply property to specify HVCC's regulator in the device tree.

"hdmi" doesn't sound like the name of the supply. "hvcc" or just "vcc" 
would be more appropriate.

Okay. In original versions it used to be "hvcc-supply", and
I will pick the name again.

[PATCH v3.1 09/10] drm/sun4i: Add support for HDMI voltage regulator

[Icenowy Zheng]

From: Jernej Skrabec <jernej.skrabec-gGgVlfcn5nU@public.gmane.org>

Some boards have HDMI VCC pin connected to voltage regulator which may
not be turned on by default.

Add support for such boards by adding voltage regulator handling code to
HDMI driver.

It was last reported as broken, so it's better to leave it out of that
patch until someone figures it out.

Sorry, I did find a bug. Although after fixing it HDMI on Pine A64+
works fine.

Will fix the bug when sending v3.2 (resending after rc1).

Why don't you simply send v4, with all patches and changelogs? It would be 
easier to comprehend.

Beside the comment on the pine64, it looks good to me. Can you
resubmit those patches after rc1 is out?
