Hello,
Here's a new version of the Xilinx ZynqMP DisplayPort Subsystem driver, the second version since I took over v8 of the series ([1]) from Hyun.
This new version only brings small changes. The most notable difference is a conversion of the DT bindings to YAML. Other small changes are described in individual patches.
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 the DMA engine driver, and we are figuring out a plan to get the PHY driver (and its DT bindings and DT integration) upstreamed. For this reason only patches 1/4 and 2/4 are currently candidate for upstreaming, the DT integration in 3/4 and 4/4 depends on the DMA engine and PHY.
In the meantime, a branch that contains this series on top fo the required dependencies is available at
