Hello,
Here's a new version of the Xilinx ZynqMP DisplayPort Subsystem driver,
the third version since I took over v8 of the series ([1]) from Hyun.
This new version is rebased on top of the DMA engine and PHY driver
changes. In particular, it uses the new interleaved cyclic DMA
transaction type
and the PHY .configure() and .power_on() operations. It
also includes reset support, which was moved out the PHY driver to the
DPSUB driver where it belongs. The DT bindings are updated accordingly.
The series depends on currently out-of-tree DMA engine ([2]) and PHY
([3]) drivers that have been posted to the corresponding mailing lists
but not merged yet. I have taken over development of both drivers, and
hope to get them upstream without too much delay. As the DRM DPSUB driver
depends on DMA engine API extensions, I plan to request a stable branch
from Vinod in order to avoid a one kernel version delay.
A branch that contains this series on top of the required dependencies
is available at
