The Versatile board can be equipped with a interface board
just named "IB2". This was created in the early 2000s for
prototyping GSM candybar phone form factor products.
The IB2 board contains:
- Cascaded interrupt controller
- Enfora Enabler GSM0308 quad-band module with antenna and
separate audio jack
- Keypad with joystick
- Sanyo 2.5" color display
- A 28-pin connector for mounting a camera
This adds a DTS file for the combination of the Versatile AB
with an IB2 daughterboard mounted, making the LED blink and
making the system controller available for drivers, such as
the panel driver.
The device tree bindings already exist in
Documentation/devicetree/bindings/arm/arm-boards.

Is this part of some master plan to increase the value of all the old
hardware that you have before selling it with the "works on mainline
Linux" feature? I'm not sure I can find any of this hardware in Arm.

Again, lacking hardware to test.

This adds the actual VGA DAC bridge that is used in the
Versatile AB, and sets the mode to 640x480 VGA.
The "clcd" clock was incorrectly named, the proper name
(from bindings) is "clcdclk". So far drivers survived
by just getting the first clock, but future drivers will
use named clocks.
We add the panel connector to the
"arm,versatile-tft-panel" as well, the signals actually
fork on the board, reaching both the VGA DAC and the
display connector.

If I remember correctly, besides being able to flip outputs via "sysreg"
there was a debug menu on the microcontroller that had options to set
the MUX to the right output before OS boot.
That brings back a lot of memories that I thought I'll never have any
use of :)

Just update with some new results from savedefconfig so we are
in sync with what has happened in Kconfig upstream.

The DRM driver is now finalized for the RealView board family,
so switch the defconfig to use this driver instead of the old
fbdev driver.

This updates the Versatile defconfig to the latest savedefconfig
results reflecting changes in Kconfig. We add in the Flash memory
support that has been available upstream for a while now.

\o/ this sounds awesome!
But I'll immediately show myself out of this thread because DT :-)
