Subject: [PATCH v11 4/4] drm/panel-simple: Read panel orientation
Date: Thu, 18 Jun 2020 02:18:42 +0300 [thread overview]
Message-ID: <20200617231842.30671-5-digetx@gmail.com> (raw)
In-Reply-To: <20200617231842.30671-1-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 panel-simple driver.
