[PATCH v2 3/7] dt-bindings: arm: fsl: Add NXP S32N79 SoC and RDB board
Posted by Ciprian Costea 1 month, 1 week ago 
From: Ciprian Marian Costea <ciprianmarian.costea@oss.nxp.com>

Add device tree binding documentation for the NXP S32N79 automotive SoC
and the S32N79 Reference Design Board (S32N79-RDB).

The S32N79 is an automotive-grade SoC featuring eight ARM Cortex-A78AE
cores organized for high-performance networking and gateway applications
in vehicles.

I believe these are ordered by fallback, so s32v > s32n.

Makes sense. I will move S32N79 entry before S32V234 in V3 patchset.

Previous use fsl,s32v234, now use nxp,s32n79, I suggest keep consistent
with existing one, use fsl,s32n79

Ah, I missed that prefix is different! Well, that I don't mind, it's
your call which prefix you want.

Ah, since they are ordered by fallback, I will keep 'nxp,s32n79*'.
Therefore, I will leave the order as is. S32N79 after S32V234.
