Ciprian Marian Costea 8e7bb66360 can: flexcan: add NXP S32G2/S32G3 SoC support
[ Upstream commit 8503a4b1a2 ]

Add device type data for S32G2/S32G3 SoC.

FlexCAN module from S32G2/S32G3 is similar with i.MX SoCs, but interrupt
management is different.

On S32G2/S32G3 SoC, there are separate interrupts for state change, bus
errors, Mailboxes 0-7 and Mailboxes 8-127 respectively.
In order to handle this FlexCAN hardware particularity, first reuse the
'FLEXCAN_QUIRK_NR_IRQ_3' quirk provided by mcf5441x's irq handling
support. Secondly, use the newly introduced
'FLEXCAN_QUIRK_SECONDARY_MB_IRQ' quirk which handles the case where two
separate mailbox ranges are controlled by independent hardware interrupt
lines.
