From: KONRAD Frederic <address@hidden>
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
