  Hi,

We follow-up the platform support series for Mobileye EyeQ5 [1] with
this reset controller patch series.

The registers are located in a shared register region called OLB
("Other Logic Block"). A single driver instance handles the three
existing reset domains, each with their custom logic:
 - We busy-wait on the first two for hardware LBIST reasons (logic
   built-in self-test).
 - Domains 0 & 2 work in a bit-per-reset fashion while domain 1 works in
   a register-per-reset fashion.

We end the series by adding the node to the platform devicetree and
reset handles to the three UARTs.

Have a nice day,
