Subject: [PATCH v2 04/10] of: property: fw_devlink: Add a devlink for panel followers
Date: Wed,  7 Jun 2023 14:49:26 -0700	[thread overview]
Message-ID: <20230607144931.v2.4.Ibf8e1342b5b7906279db2365aca45e6253857bb3@changeid> (raw)
In-Reply-To: <20230607215224.2067679-1-dianders@chromium.org>

Inform fw_devlink of the fact that a panel follower (like a
touchscreen) is effectively a consumer of the panel from the purposes
of fw_devlink.

NOTE: this patch isn't required for correctness but instead optimizes
probe order / helps avoid deferrals.

Signed-off-by: Douglas Anderson <dianders@chromium.org>

Since this is so small, I'd presume it's OK for it to go through a DRM
tree with the proper Ack. That being said, this patch is just an
optimization and thus it could land completely separately from the
rest and they could all meet up in mainline.

Changes in v2:
- ("Add a devlink for panel followers") new for v2.
