[RESEND PATCH v6 0/8] mfd: Add OF device table to I2C drivers that are missing it

[Javier Martinez Canillas]

Hello,

This series add OF device ID tables to mfd I2C drivers whose devices are
either used in Device Tree source files or are listed in binding docs as
a compatible string.

That's done because the plan is to change the I2C core to report proper OF
modaliases instead of always reporting a MODALIAS=i2c:<foo> regardless if
a device was registered via DT or using the legacy platform data mechanism.

So these patches will make sure that mfd I2C drivers modules will continue
to be autoloaded once the I2C core is changed to report proper OF modalias.

Users didn't have a vendor prefix in the used compatible strings, but since
there wasn't a DT binding document for these drivers, it can be said that
were working for mere luck and so this series fixes the users and add a DT
binding doc for the drivers.

Most patches can be applied independently, with the exception of patches
2 to 4 that should be applied in the same tree to keep bisect-ability. I
suggest these to go through the MFD subsystem tree.

Best regards,
Javier

[RESEND PATCH v6 5/8] i2c: i2c-cbus-gpio: Add vendor prefix to retu node in example

[Javier Martinez Canillas]

The example contains a device node for a retu device, but
its compatible string doesn't have a vendor prefix.

While being there, drop the -mfd suffix since isn't correct.

Are you planning to pick this series? It has been in the list for
months and were resent many times...

I think you exaggerate a little.  Your last Ack (from Linus) was only
collected in v6, which has only been resent once with that Ack
applied. =:)

We are currently only half way through the merge-window.  This patch
will be hoovered up during the early -rcs.  Please be patient around
the time of the merge-window, since Maintainers are either usually
very busy with pull-requests, or taking a 2 minute breather before
the chaos starts over.

You are right, sorry for the impatience.

Great, I just was worried that it could fell through the cracks.
Thanks for your answer.
