Hi All,

Here is more or less a resend of v1 of my second attempt at dealing with
multiple i2c devices being described in a single ACPI fwnode.

The only change is that it has been rebased from v4.17 to v4.18-rc2.

Mika, Andy and Heikki, can you review this please?

Ping? It would be good to get some sort of resolution for
this problem / this patch-set.

As mentioned in an earlier reply in this thread, the only alternative
to this patch-set which I see would be to duplicate the list of
ACPI HIDs found in the new drivers/i2c/i2c-multi-instantiate.c
inside code under drivers/acpi and make the acpi code not
skip enumerating devices with these HIDs as platform drivers.

Then the i2c-multi-instantiate.c driver could become a
platform driver (*) and the I2C_CLIENT_IGNORE_BUSY
flag / hack can go away (at the price of duplicating
the HIDs in 2 places).

I'm certainly open to taking a shot at doing things that
way, but getting some feedback first and an indication
from the ACPI folks (Mika?) that that would be acceptable
would be nice.

Regards,

Hans


*) And probably be moved to drivers/platform/x86
