Hi,

First two patches are about adding Mobileye EyeQ6H support to the
Nomadik I2C controller driver, in the same vein as was done a few
months ago for EyeQ5.
 - dt-bindings wise, it is only a new compatible. EyeQ6H does NOT
   require the same mobileye,olb custom prop as EyeQ5.
 - driver wise, we are again on a 32bit memory bus, so reuse
   the .has_32b_bus flag.

Next two patches are about supporting higher speeds (fast-plus and
high-speed).
 - Fix computation of the bus rate clock divider (BRCR). It picks the
   smallest divider that gives a bus rate above target. Switch to
   picking the largest divider that gives a bus rate below target.
 - Then support high SM (speed-mode) values. This is not much work.

It works on EyeQ6H HW just fine. 1MHz has been tested but not 3.4MHz
because HW doesn't support it. The theory is there, and BRCR
computation has been checked to be valid with 3.4MHz clocks.

DTS patches are not provided because they depend on the platform's clock
series [0]. Lore being down at the moment, see Patchwork [1].

Have a nice day,
Théo
