The Amlogic G12A SoC offers very close Video Display
functionnalities with it's older GXBB, GXL & GXM predecessors.
The main differences are :
- G12A Support now 3 "real" OSD planes with a new Blender module
- Instead of having a single Scaler for OSD1, G12A has two scaler
that can be applied to 2 out of the 3 OSD planes or on the outputs
of the blender module.
- The HDMI PHY now support RX-SENSE, Dynamic HDR and it's registers are
now memory mapped instead of using an internal bus.
- The VPU now support a DSI interface to connect a display, using
the Synopsys DSI controller and a custom PHY
The complex Blender routing, HDMI RX-SENSE, Dynamic HDR and DSI support
are not handled in this patchset.
This patchset implements on-par support with the currently support
GXBB, GXL and GXM SoCs. There is no support delta with this patchset.
patch 10 & 11 implements the bindings found at [1].

2.21.0
The Amlogic G12A embeds the same Synopsys DW-HDMI Controller,
but with :
- a "backport" of the HDR signaling registers from more recent
DW-HDMI controllers, this will need a tweak since it's not
normally present on this version of the DW-HDMI controller
- A direct mapping of TOP and DW-HDMI registers instead of an
internal bus accessed using read/write registers
- Support for RX-SENSE, but not yet implemented
- Support for HDMI 2.1 Dynamic HDR, but not yet implemented
- Different registers mapping for the HDMI PHY setup
This patchs adds support for these changes while providing exact
same support as the previous GXBB, GXL & GXM SoCs.

This patch adds support for the new OSD+VD Plane blending module
in the CRTC code by adding the G12A code to manage the blending
module and setting the right OSD1 & VD1 plane registers.

2.21.0
While switching to the Common Clock Framework is still Work In Progress,
this patch adds the corresponding G12A HDMI PLL setup to be on-par
with the other SoCs support.
The G12A has only a single tweak about the high frequency setup,
where the HDMI PLL needs a specific setup to handle correctly the
5.94GHz DCO frequency.
Apart that, it handle correctly all the other HDMI frequencies
and can achieve even better DMT clock frequency precision with
the larger fractional dividier width.

On Amlogic G12A SoC, the 2,97GHz PLL frequency is not stable enough
to provide a correct 297MHz pixel clock, so switch the PLL base
frequency with a /2 OD when the 297MHz pixel clock is requested.
This solves the issue on G12A and also works fine on GXBB, GXL & GXM.

Amlogic G12A SoC supports the same set of Video Planes, but now
are handled by the new OSD plane blender module.
This patch uses the same VD1 plane for G12A, using the exact same scaler
and VD11 setup registers, except using the new blender register to
disable the plane.

This patch uses the same OSD1 plane G12A, using the exact same scaler
and OSD1 setup registers, except using the new blender register to
disable the plane.

Can you define some of the masks and shifts above ? possibly the same define
for all the registers I suppose ... maybe using FIELD_PREP ?

Maybe the values above are just magics taken from the vendor kernel, but if
you can, it would be nice to break them down to help us understand what is
controlled in these CTNL registers.

Could you make a local variable for priv->io_base + meson_crtc->viu_offset ?
It would be a little easier to read

I can't pretend to have a deep understanding of this subsystem, but as far as

of *_is_compatible() functions. I think it would make the code easier to
follow and review.

Thanks for the overall review,
I will do a complete fixup of the constants and defines in a follow-up patchset,
since the already-merged code also needs a good cleanup.
I'll do a more complete refactoring to get rid of the _is_compatible() stuff
in a second time, it needs much more work to handle correctly the 4 SoC families.
