The mdp5 kms driver currently sets up multiple encoders per interface (INTF), one for each kind of mode of operation it supports. We create 2 drm_encoders for DSI, one for Video Mode and the other for Command Mode operation. The reason behind this approach could have been that we aren't aware of the DSI device's mode of operation when we create the encoders. This makes things a bit complicated, since these encoders have to be further attached to the same DSI bridge. The easier way out is to create a single encoder, and make the DSI driver set its mode of operation when we know what the DSI device's mode flags are. Start with providing a way to set the mdp5_intf_mode using a kms func that sets the encoder's mode of operation. When constructing a DSI encoder, we set the mode of operation to Video Mode as default. When the DSI device is attached to the host, we probe the DSI mode flags and set the corresponding mode of operation.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
