Subject: [PATCH v4 0/2] Fix simple-bus issues with fw_devlink
Date: Tue, 28 Sep 2021 17:07:32 -0700 [thread overview]
Message-ID: <20210929000735.585237-1-saravanak@google.com> (raw)
Ulf reported an issue[1] with fw_devlink. This series tries to fix that
issue.
I replicated a similar set up on my end and I confirmed:
- A simple-bus only device is probed.
- Another device listing simple-bus as a 2nd compatible string isn't
probed.
v1->v2:
- Switched to probing the simple-bus device instead of marking it as
NEVER_PROBES.
v2->v3:
- Moved all the code into the simple-pm-bus driver
- Addressed Ulf's comment about the remove() code missing a check.
v3->v4:
- Added support for driver_override to accommodate the case where new
transparent bus compatible strings are added to DT, but the kernel hasn't
been updated yet.
- Added/updated comments to give more details.
- Adding Ulf's Tested-by that he have for v3 (v4 didn't change by much).
Thanks,
Saravana
