The hold field allows to configure the data hold time which can be set
with the help of the generic binding 'i2c-sda-hold-time-ns'. This
feature has been introduced with SAMA5D4 SoC family.

Changes:
- from v1:
- fix typos,
- change MAX_HOLD macro to follow Nicolas' advice,
- make it clear that sama5d2 also support i2c-sda-hold-time-ns.
Ludovic Desroches (4):
i2c: at91: add support for the HOLD field
i2c: at91: update bindings documention
ARM: at91/dt: sama5d4: update i2c

Series of patches that enable support for Knights Landing processor which is
based on Silvermont microarchitecture.
First 3 patches are pretty much straightforward and self-explantory.
Last one is the biggest, however, is logically consistent and breaking into
many smaller patches does not make

Knights Landing is gen next architecture for HPC market.
KNL introduces concept of a tile and CHA - Cache/Home Agent for
memory accesses.
Some things are fixed in KNL:
() There's single DIMM slot per channel
() There's 2 memory controllers with 3 channels each, however,
