[PATCH 0/2] Add of match tables for the ChromeOs EC subdevices

[Sjoerd Simons]

The ChromeOS EC MFD driver registers its sub-devices with both a (platform)
name and an of compatibility string. As a result of this the modalias passed on
to user-space will be based on the of compatibility string. Thus to be able to
rely on autoloading in case the subdevices are build as modules they need to
export the necessary module aliases based to match the of information.

The two patches in these series add the requird of match information to the EC
subdevices

Hmm, looks like the rtc-ds1742.c driver is the only one in the kernel
tree using that strategy, while all others use #ifdef CONFIG_OF. So i'm
inclined to keep the #ifdef here, ooi what is your rationale behind
suggesting __maybe_unused?

I agree with Sjoerd on this. Not only using the #ifdef guards makes it
more evident when reading the code that this depends on OF being
enabled but also if using __maybe_unused an entry in the struct
of_device_id table will be added for no reason.

[PATCH 0/2 v2] Add OF match tables for the ChromeOs EC subdevices

[Sjoerd Simons]

[ This is essentially a resend, adding Javiers reviewed-by and fixing some small
identation issues in the second patch. Also added Wolfgang and Dimitry in the
to, as i missed them last time ]

The ChromeOS EC MFD driver registers its sub-devices with both a (platform)
name and an OF compatibility string. As a result of this the modalias passed on
to user-space will be based on the OF compatibility string. Thus to be able to
rely on autoloading in case the subdevices are build as modules they need to
export the necessary module aliases based to match the of information.

The two patches in these series add the requird of match information to the EC
subdevices

I guess the first patch should through the i2c tree while the second one would
be for the input tree?

[PATCH 2/2] input: cros_ec_keyb: Add of match table

[Sjoerd Simons]

To enable the cros_ec_keyb driver to be auto-loaded when build as
module add an of match table (and export it) to match the modalias
information passed on to userspace as the Cros EC MFD driver registers
the MFD subdevices with an of_compatibility string.
