Subject: [PATCH v5 1/7] dt-bindings: Add panel-timing subnode to simple-panel
Date: Mon, 1 Apr 2019 10:17:18 -0700 [thread overview]
Message-ID: <20190401171724.215780-2-dianders@chromium.org> (raw)
In-Reply-To: <20190401171724.215780-1-dianders@chromium.org>
From: Sean Paul <seanpaul@chromium.org>
This patch adds a new subnode to simple-panel allowing us to override
the typical timing expressed in the panel's display_timing.
Changes in v2:
- Split out the binding into a new patch (Rob)
- display-timings is a new section (Rob)
- Use the full display-timings subnode instead of picking the timing
out (Rob/Thierry)
Changes in v3:
- Go back to using the timing subnode directly, but rename to
panel-timing (Rob)
Changes in v4:
- Simplify desc. for when override should be used (Thierry/Laurent)
- Removed Rob H review since it's been a year and wording changed
Changes in v5:
- Removed bit about OS may ignore (Rob/Ezequiel)
