[PATCH v3 0/7] 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.

It's safe to apply the patches independently.

Best regards,
Javier

Changes in v3:
- Add a vendor prefix to the compatible string (Rob Herring).
- Add a vendor prefix to the compatible string (Rob Herring).

Changes in v2:
- Don't use of_match_ptr() to avoid build warning when CONFIG_OF is disabled.
- Don't use of_match_ptr() to avoid build warning when CONFIG_OF is disabled.

[PATCH v3 4/7] ARM: dts: n8x0: Add vendor prefix to retu node

[Javier Martinez Canillas]

The retu-mfd device node doesn't have a vendor prefix
in its compatible string, fix it by adding one.
