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.

Best Regards,
Fred
