Subject: [PATCH v2 6/6] arm64: dts: sdm845: Add "no-hpd" to sn65dsi86 on cheza
Date: Mon, 20 Apr 2020 22:06:22 -0700 [thread overview]
Message-ID: <20200420220458.v2.6.I89df9b6094549b8149aa8b8347f7401c678055b0@changeid> (raw)
In-Reply-To: <20200421050622.8113-1-dianders@chromium.org>
We don't have the HPD line hooked up to the bridge chip. Add it as
suggested in the patch ("dt-bindings: drm/bridge: ti-sn65dsi86:
Document no-hpd").
NOTE: this patch isn't expected to have any effect but just keeps us
cleaner for the future. Currently the driver in Linux just assumes
that nobody has HPD hooked up. This change allows us to later
implement HPD support in the driver without messing up sdm845-cheza.
Signed-off-by: Douglas Anderson <dianders@chromium.org>

Changes in v2:
- ("arm64: dts: sdm845: Add "no-hpd" to sn65dsi86 on cheza") new for v2.
