Sorry, I obviously meant to write a message here.

The s32g devices have a GPR register region which could be accessed
via a syscon. Currently only the stmmac/dwmac-s32.c uses anything
from there and we just add a line to the device tree to access
that GMAC_0_CTRL_STS register:

reg = <0x4033c000 0x2000>, /* gmac IP */
<0x4007c004 0x4>; /* GMAC_0_CTRL_STS */

But it would be better to have a syscon instead of adding each
register to the device tree like this.

We still have to maintain backwards compatibility to this format,
of course.
