Hi all,
just noticed a build breakage in Xenomai 2: ksrc/drivers/can/flexcan.c
is looking for linux/can/platform/flexcan.h which was removed in
baffd2e8d9. But both the Xenomai driver and upstream's flexcan.c still
use the flexcan_platform_data structure which I do not find anywhere in
the kernel. Does anyone know what happened there?

I just cloned Linus's kernel tree and do *not* see that any CAN driver is
still including "linux/can/platform/flexcan":
$ grep -r '/platform/flexcan.h' linux/drivers/net/can/
$
Will have a closer look later today.

Also try "git grep flexcan_platform_data" - confuses me...

Well, the driver never uses the contents of the pointer to this
structure, so, it does not really need the structure to be defined...
Or am I missing something? Anyway, it would seem the driver has been
converted to device tree:

Indeed, dead code...

Then we need to convert the RT driver as well, right?

Yes... while still being compatible with old(er) kernel versions.
And there are various other improvements and most likely bug fixes.
Unfortunately I do currently not have Flexcan hardware at hand.
