Use devm_request_irq() for irq allocation which
simplify driver code.

Changes in v2:
- Disable interrupts in xilinx_spi_remove() to be sure
that interrupt won't come between struct freeing
and devres irq unregistration.

What do you exactly

Does it mean that you are able to see loading file there?
Can you share your script?

have agreement on this another valid discussion is
if firmware interface is OK for this purpose or NOT. Or if make sense
to create different interface or have all of them.

1) The driver doesn't know what firmware to request. It just knows
how to send it to a FPGA.
But dts property in the manager driver which uses this as end driver
can know
by gpio interface and you can program another fpga from zynq (This can
be probably generic case for any combination in this 4 pin connection).

what options there are for cplds.
But anyway AFAIK richer formats are not problem for us.
The same situation should be for partial bitstreams too.
Thanks,

I acked-by the patches, so if someone is willing to take the patches I
am ok with that. I am ok also to pick them into my tree with the
acked-by maintainer. Just let me know ...
Yes, please add also this zynq specific patch through your tree.
Here is my ACK for that.

Some pl330 have per channel irq and it is necessary
to allocate all of them. Loop over irq assigned for this
device to support these pl330 IPs.
For example this IP is available on Xilinx Zynq platform.

Hi Vinod,
this is the patch I told
This patch is inpired by the patch for drvdata
device-core: Ensure drvdata = NULL when no driver is bound
(sha1: 0998d0631001288a5974afc0b2a5f568bcdecb4d)
Also it fixes all occurences in drivers.
