We should move all callers to use mipi_dsi_generic_write_seq_multi() -and mipi_dsi_dcs_write_seq_multi() macros instead. - -Once all callers are transitioned, the macros and the functions that they call, -mipi_dsi_generic_write_chatty() and mipi_dsi_dcs_write_buffer_chatty(), can -probably be removed. Alternatively, if people feel like the _multi() variants -are overkill for some use cases, we could keep the mipi_dsi_*_write_seq() -variants but change them not to return out of the caller. +Transition away from using deprecated MIPI DSI functions +-------------------------------------------------------- + +There are many functions defined in ``drm_mipi_dsi.c`` which have been +deprecated. Each deprecated function was deprecated in favor of its `multi` +variant (e.g. `mipi_dsi_generic_write()` and `mipi_dsi_generic_write_multi()`). +The `multi` variant of a function includes improved error handling and logic +which makes it more convenient to make several calls in a row, as most MIPI +drivers do. + +Drivers should be updated to use undeprecated functions. Once all usages of the +deprecated MIPI DSI functions have been removed, their definitions may be +removed from ``drm_mipi_dsi.c``. Contact: Douglas Anderson <dianders@chromium.org> |
