[Qemu-devel] [PATCH 0/8] Xilinx DisplayPort.

[fred.konrad@greensocs.com]

From: KONRAD Frederic <fred.konrad@greensocs.com>

This is the implementation of the Xilinx DisplayPort and DPDMA

This patch-set is rebased on Peter Crosthwaite patch-set currently on the list:
http://lists.nongnu.org/archive/html/qemu-devel/2015-05/msg01302.html

Details of the DPDMA part:
 * DPDMA is implemented as a QEMU SYSBUS device.
 * Interrupts are implemented except the axi error and fifo.

Details of the XILINX-DP:
 * DP is also implemented as a QEMU SYSBUS. Multiple memory regions are used to
   avoid having a single big region as there are holes in the DP memory map.
 * An aux-bus has been implemented, it creates a memory map for aux slaves and
   has an i2c bus (which is already implemented in QEMU).
 * The normal programmable i2c clock and controller implementation is missing
   from the QEMU tree so the easiest way for us was to implement a dummy-clk
   driver in the kernel. It's a clock which does nothing but fakes a clock such
   that the DPDMA driver works. The patch will be send separately.
 * The graphic plane works on channel 3, video on channel 0 and audios on
   channel 4 and 5.

Thanks,
Fred
