What happend to that branch? FWIW I've just tried the patches on a custom
board with a LS1028A SoC. Both CAN and CAN-FD are working. I've tested
against a Peaktech USB CAN adapter. I'd love to see these patches upstream,
because our board also offers CAN and basic support for it just made it
upstream [1].

If these patches are upstream, only the device tree nodes seems to be
missing. I don't know what has happened to [2]. But the patch doesn't seem
to be necessary.

Pankaj already send a patch to add the device node to the LS1028A [3].
Thats basically the same I've used, only that mine didn't had the
"fsl,ls1028ar1-flexcan" compatiblity string, but only the
"lx2160ar1-flexcan" which is the correct way to use it, right?

Sorry for putting this all in one mail, but I've just subscribed to
linux-can and there is no message archive on lore.kernel.org for it :/
