Hi Sudeep/Lorenzo,
this series of 4 patches (maybe you have even queued the first
patch) will switch the Versatile Express over to using the
new PL111 DRM driver instead of the old fbdev driver.
There are both DTS updates and defconfig updates. Surely too
late for v4.18 but should be fine for v4.19 (I will likely
remind you if you forget it after v4.18-rc1.) The defconfig
and DTS need to changed in lockstep, but usually the ARM
SoC maintainers want them as two separate pull requests
anyway.
I think this could be quite useful, hopefully enabling things
such as the generic Android and Chromium DRM hwcomposer:
https://memcpy.io/android-enabling-mainline-graphics.html
the improvement will be most drastic on the CA0 Versatile
Express as this has only PL111 graphics on the core tile,
but the fallback PL111 on the motherboard is also working
for all models now.
We are using CMA and CMA DMA buffers with existing DT
bindings to hammer the system down to use the assigned
special memory when we use the PL111 on the motherboard.
Please queue this in your Versatile Express tree.
To complete the transition for PL111 DRM for all ARM reference
designs only Integrator/CP remains because of the special RGBA
5551 mode, but I will fix that too, hopefully also in time for
kernel v4.19.
The QEMU system emulator model for Versatile Express has been
patched to certainly cope with these new changes as well:

It is a bit unorthodox to just include a file in the middle
of a another DTS file, it breaks the pattern from other device
trees and also makes it really hard to reference things
across the files with phandles.
Restructure the include for the Versatile Express motherboards
to happen at the top of the file, reference the target nodes
directly, and indent the motherboard .dtsi files to reflect
their actual depth in the hiearchy.
This is a purely syntactic change that result in the same
DTB files from the DTS/DTSI files.

* [PATCH 1/4] ARM: dts: Restructure Vexpress motherboard includes
@ 2018-05-28 12:26 ` Linus Walleij
0 siblings, 0 replies; 20+ messages in thread
From: Linus Walleij @ 2018-05-28 12:26 UTC (permalink / raw)
To: Sudeep Holla, Lorenzo Pieralisi, linux-arm-kernel
Cc: Liviu Dudau, dri-devel, Mali DP Maintainers, Robin Murphy
It is a bit unorthodox to just include a file in the middle
of a another DTS file, it breaks the pattern from other device
trees and also makes it really hard to reference things
across the files with phandles.
Restructure the include for the Versatile Express motherboards
to happen at the top of the file, reference the target nodes
directly, and indent the motherboard .dtsi files to reflect
their actual depth in the hiearchy.
This is a purely syntactic change that result in the same
DTB files from the DTS/DTSI files.

* [PATCH 2/4] ARM: dts: Modernize the Vexpress PL111 integration
2018-05-28 12:26 ` Linus Walleij
@ 2018-05-28 12:26 ` Linus Walleij

From: Linus Walleij @ 2018-05-28 12:26 UTC (permalink / raw)
To: linux-arm-kernel
The Versatile Express was submitted with the actual display
bridges unconnected (but defined in the device tree) and
mock "panels" encoded in the device tree node of the PL111
controller.
This doesn't even remotely describe the actual Versatile
Express hardware. Exploit the SiI9022 bridge by connecting
the PL111 pads to it, making it use EDID or fallback values
to drive the monitor.
The also has to use the reserved memory through the
CMA pool rather than by open coding a memory region and
remapping it explicitly in the driver. To achieve this,
a reserved-memory node must exist in the root of the
device tree, so we need to pull that out of the
motherboard .dtsi include files, and push it into each
top-level device tree instead.
We do the same manouver for all the Versatile Express
boards, taking into account the different location of the
video RAM depending on which chip select is used on
each platform.
This plays nicely with the new PL111 DRM driver and
follows the standard ways of assigning bridges and
memory pools for graphics.

ChangeLog v1->v2:
- Fix up the memory address for the -rs1 tiles to 0x18000000
- Drop a bunch of extraneous reg props from the DVI adapter

* [PATCH 2/4] ARM: dts: Modernize the Vexpress PL111 integration
@ 2018-05-28 12:26 ` Linus Walleij
0 siblings, 0 replies; 20+ messages in thread
From: Linus Walleij @ 2018-05-28 12:26 UTC (permalink / raw)
To: Sudeep Holla, Lorenzo Pieralisi, linux-arm-kernel
Cc: Liviu Dudau, dri-devel, Mali DP Maintainers, Robin Murphy
The Versatile Express was submitted with the actual display
bridges unconnected (but defined in the device tree) and
mock "panels" encoded in the device tree node of the PL111
controller.
This doesn't even remotely describe the actual Versatile
Express hardware. Exploit the SiI9022 bridge by connecting
the PL111 pads to it, making it use EDID or fallback values
to drive the monitor.
The also has to use the reserved memory through the
CMA pool rather than by open coding a memory region and
remapping it explicitly in the driver. To achieve this,
a reserved-memory node must exist in the root of the
device tree, so we need to pull that out of the
motherboard .dtsi include files, and push it into each
top-level device tree instead.
We do the same manouver for all the Versatile Express
boards, taking into account the different location of the
video RAM depending on which chip select is used on
each platform.
This plays nicely with the new PL111 DRM driver and
follows the standard ways of assigning bridges and
memory pools for graphics.

ChangeLog v1->v2:
- Fix up the memory address for the -rs1 tiles to 0x18000000
- Drop a bunch of extraneous reg props from the DVI adapter

* [PATCH 4/4] ARM: defconfig: Enable the PL111 DRM driver on vexpress

To: linux-arm-kernel
This updates the Versatile defconfig to use the new P111 DRM
driver that is merged in the DRM subsystem.
We deactivate the old CLCD driver and activate the Pl111 DRM
driver and the SiI9022 HDMI bridge.
We activate DMA memory allocation using CMA so that the special
graphics memory for the on-board CLCD can be used.

Is it different from v1/earlier version you had posted ?
I have already sent this to ARM SoC and it should be in -next by now.
I will add the remaining 3 patches for v4.19 once you confirm
that I can drop this patch as it's already queued.

Don't think so. Just resent it as part of the rest.

I need to think hard yet, but was hoping to keep these in the
motherboard files itself if possible. I don't like the way we need
to specify the absolute address here.

I can't find dvi_bridge_in for this RTSM/FVP model, also not sure if I2C
or DVI transmitter is supported on them.
Liviu, any idea ?
Also you my need to fix arm64 express-v2f-1xv7-ca53x2.dts as it includes
vexpress-v2m-rs1.dtsi

Models don't have any bridges or DVI transmitters, they use the
framebuffer address that gets programmed into the PL111 registers as the
address where they read from in order to render to screen. At least that
is what happens for HDLCD, I'm afraid I have limited knowledge about the
PL111 implementation in the model.
