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

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