Subject: [PATCH v6 2/8] drm/i2c: adv7511: Move to bridge folder
Date: Fri, 17 Jun 2016 13:23:29 +0530 [thread overview]
Message-ID: <1466150015-882-3-git-send-email-architt@codeaurora.org> (raw)
In-Reply-To: <1466150015-882-1-git-send-email-architt@codeaurora.org>
The driver has been converted to use drm_bridge instead of
drm_i2c_slave_encoder. We can now move it to the bridge folder.
Create a separate folder since we already have a couple of files and
expect more when we support audio and ADV7533.
Rename the driver to adv7511_drv.c. This will come in handy later
when the driver module will need to be built from multiple object
files.
