Description

While MIPI DSI bus and MIPI devices has been supported in Linux kernel for quite a while, during the last few years several important corner cases were identified, which make it hard to fit the MIPI DSI devices into the standard DRM pre-enable / enable / disable / post-disable model. Some of the shortcomings were solved via the pre_enable_prev_first call, other shortcomings remain unsolvd. This session describes a proposed solutions for the MIPI DSI drivers model.
