Indeed! According the Wikipedia it got released to market on 2021, which
does sound recent from a MIPS standpoint. (The same year MIPS announced
the architecture would stop being developed in favor of RISC-V.)

That is the goal. There are two dependencies in this series:

 - MIPS stuff depends on the base platform support series by Gr=C3=A9gory,
   for devicetree stuff & MAINTAINERS mostly.
 - "dt-bindings: soc: mobileye: add EyeQ5 OLB system controller" depends
   on the three dt-bindings for the controllers (clk+reset+pinctrl) as
   it references them.

That means clk+reset+pinctrl can go in separately. At least that is the
goal, hoping I have not messed up along the way.

Thanks,
