[PATCH v3 0/4] xlnx-zcu102: fix the display port.

[frederic.konrad]

From: Frederic Konrad <fkonrad@amd.com>

Hi,

This patch set fixes some issues with the DisplayPort for the ZCU102:

The first patch fixes the wrong register size and thus the risk of register
overflow.

The three other one add a vblank interrupt required by the linux driver:
  - When using the VNC graphic backend and leaving it unconnected, in the best
    case the gfx_update callback is called once every 3000ms which is
    insufficient for the driver.  This is fixed by providing a VBLANK interrupt
    from a ptimer.
  - This requirement revealed two issues with the IRQ numbers and the
    interrupt disable logic fixed by the two last patches.

Tested by:
  - booting Petalinux with the framebuffer enabled.
  - migrating the running guest and ensure that the vblank timer still fire 
correctly.

Best Regards,
Fred

v2 -> v3:
  * Added a VMSTATE in order to migrate the vblank timer as suggested
    by Peter Maydell (Patch 2).
  * Rebased on 0cac736e.
v1 -> v2:
  * Better use of the ptimer API by using a correct POLICY as suggested
    by Peter Maydell (Patch 2).
  * Rebased on 78ac2eeb.
