Subject: [PATCH v3 0/3] add FlexCAN support for S32G2/S32G3 SoCs

From: Ciprian Marian Costea <ciprianmarian.costea@....nxp.com>

S32G2 and S32G3 SoCs share the FlexCAN module with i.MX SoCs, with some
hardware integration particularities.

Main difference covered by this patchset relates to interrupt management.
On S32G2/S32G3 SoC, there are separate interrupts for state change, bus
errors, MBs 0-7 and MBs 8-127 respectively.

The intent of this patchset is to be upstream'ed on the official Linux
repo [0].

Since S32G2/S32G3 SoCs share the FlexCAN controller with I.MX platforms,
we find value in an allignment on Linux Factory tree [1]. Hence, we are
looking forward to integrate any feedback which you have based on your
expertise on this proposed patchset, before finally submitting upstream
for review.
