We are currently restricted when it comes to supporting DSI on devices that have a non-DSI control bus. For example, DSI encoder chips are available in the market that are configured via i2c. Configuring their registers via DSI bus is either optional or not available at all. These devices still need to pass DSI parameters (data lanes, mode flags etc) to the DSI host they are connected to. We don't have a way to do that at the moment. The method presented in these patches is to provide an API to create a 'dummy' mipi_dsi_device. This device is populated with the desired DSI params, which are passed on to the host via mipi_dsi_attach(). This method will require the device driver to get a phandle to the DSI host since there is no parent-child relation between the two. Is there a better way to do this? Please let me know!
