Subject: [PATCH v2 01/10] dt-bindings: soc: mobileye: Add EyeQ7H OLB
The Other Logic Blocks (OLB) found in Mobileye SoCs contain hardware
sub-functions grouped in a logical device.
The EyeQ7H features 14 such OLB. The main differences with the previous
generation of SoC are that some blocks have two clock sources instead
of one and that the clock source can be the one of the clock output of
another OLB instead of the main oscillator.
For the blocks with a single parent clock, the name of that clock is
"ref", similar to what is done for the OLB of the previous SoC. The
blocks with two parent clocks use either "ref" for the main oscillator,
"ref_100p0" for a 100MHz reference clock or "ref_106p6" for 106.6MHz
reference clock.
Some OLB also contain a reset controller with one or more reset domain,
like the blocks found in the EyeQ6H.

+description:
+ OLB ("Other Logic Block") is a hardware system controller grouping
+ smaller blocks. Clocks and resets are generated by those blocks and
+ used by internal controllers of the SoC. The EyeQ7H SoC hosts 14
