#1406882 — [PATCH 0/2] arm: dra7: Add i2c6 instance hwmod and dt entries

DRA72x devices have a sixth i2c ocntroller instance.
Following patches add the required hwmod structure and
device tree nodes.

Reference doc: DRA72x TRM [ SPRUHP2Q ]

Tested on :
DRA72x Rev B EVM

  arm: dra7: Add hwmod entry for i2c6
  dts: dra7: Add device tree node for i2c6

NAK. reasoning:
a) i2c6 is a custom IP integration with completely non-standard
dependencies with cross device dependencies for pretty much a specific
usecase -> usage is pretty much limited for generic support - the
decision is NOT to support this instance in Linux kernel - internal
discussion forwarded to developer.
b) the patches themselves are wrong -> it applies to DRA72x not
generic DRA7x platform
c) patches themselves are in the wrong format (wrong subject line etc).
d) patches don't handle the SoC internal device dependencies either ->
in short will not function in a generic solution for all variations of
platforms.

Yes please drop this, attempting to support it in upstream is just going 
to cause unnecessary pain.
