Hi Jacopo, Thanks for your patch!

They are not identical: - M3-N does not have the CA53-related areas, - M3-W does not have A3VP, - M3-N does not have A2VC0 (M3-W also doesn't, according to latest datasheet?). The datasheet also mentions A3SH, without further info about the register block.

Why do I still see that power area listed in latest renesas-drivers for M3-W? Are there patch pendings for that? I'll remove it anyway for M3-N.
