Hi,
I'm posting a driver for TW686[4589]-based PCIe cards. The first patch
has been posted and reviewed by Ezequiel back in July 2015, the
subsequent patches are changes made in response to the review and/or are
required by the more recent kernel versions.
This driver lacks CMA-based frame mode DMA operation, I'll add it a bit
later. Also:
- I haven't converted the kthread to a workqueue - the driver is
modeled after other code and it can be done later, if needed
- I have skipped suggested PCI ID changes and the 704 vs 720 pixels/line
question - this may need further consideration.
Please merge.
The following changes since Linux 4.4 are available in the git
repository at:
