Guys:
I think the Silicon Motion SM501 driver might provide a useful
example, since the chip comes in both memory-mapped and PCI versions.
Unfortunately the chip is implemented as a multi-function driver
(mfd), so the code is not un-complicated. Still fairly
straightforward and well-written once
Hi,
Please review and acknowledge this patch.

Thanks for the feedback David, I appreciate it. Could you point me to one
of those drivers that has "this sort of dual bus binding" so can see an
example of what I'm trying to do?

Ben,
How do you want to work this? Do you want to ack it and I take this
patch with the others through the tracing tree, or do you want to wait
till the tracing tree gets updated into mainline and then pull this in
though the ppc tree. As this touches a bit of the ppc side.

This adds support for programming the data processing FPGAs on the OVRO
CARMA board. These FPGAs have a special programming sequence that
requires that we program the Freescale DMA engine, which is only
available inside the kernel.

This driver allows userspace to access the data processing FPGAs on the
OVRO CARMA board. It has two modes of operation:
1) random access
This allows users to poke any DATA-FPGA registers by using mmap to map
the address region directly into their memory map.
2) correlation dumping
When correla
Hello everyone,
This is the fourth posting of these drivers, taking into account comments
from earlier postings. The DMAEngine patches are in mainline now, and
therefore are not part of this series anymore.
RFCv3 -> RFCv4:
- updates for DATA-FPGA version 2
RFCv2 -> RFCv3:
- use miscdevice framew
If firmware allows us to map all of a partition's memory for DMA on a
particular bridge, create a 1:1 mapping of that memory. Add hooks for
dealing with hotplug events. Dyanmic DMA windows can use larger than the
default page size, and we use the largest one possible.

dwc_read_reg32 is used nowhere throughout the code. One of dwc_read32 and
dwc_read_reg32 should be removed IMO. There was once only dwc_read_reg32. In
version 5 of your patchset I believe. Why did you add another function?
AFAIK it is not correct to store pointers in u32 because they need 8 bytes
