Subject: [PATCH v2 2/5] drm/panel: lvds: Set up panel orientation
Date: Sun, 14 Jun 2020 23:01:18 +0300 [thread overview]
Message-ID: <20200614200121.14147-3-digetx@gmail.com> (raw)
In-Reply-To: <20200614200121.14147-1-digetx@gmail.com>
The panel orientation needs to parsed from a device-tree and assigned to
the panel's connector in order to make orientation property available to
userspace. That's what this patch does for the generic LVDS panel.
