Now that we're using lists instead of kfifo to store drm flip-work tasks we do not need the size parameter passed to drm_flip_work_init function anymore. Moreover this function cannot fail anymore, we can thus remove the return code. Modify drm_flip_work_init users to take account of these changes.

Boris BREZILLON authored
Make use of lists instead of kfifo in order to dynamically allocate task entry when someone require some delayed work, and thus preventing drm_flip_work_queue from directly calling func instead of queuing this call. This allow drm_flip_work_queue to be safely called even within irq handlers. Add new helper functions to allocate a flip work task and queue it when needed. This prevents allocating data within irq context (which might impact the time spent in the irq handler). Signed-off-by:

This panel requires dual-channel mode. The device accepts command-mode data on 8 lanes and will therefore need a dual-channel DSI controller. The two interfaces that make up this device need to be instantiated in the controllers that gang up to provide the dual-channel DSI host. Reviewed-by:

Currently the mipi_dsi_dcs_write() function requires the DCS command byte to be embedded within the write buffer whereas mipi_dsi_dcs_read() has a separate parameter. Make them more symmetrical by adding an extra command parameter to mipi_dsi_dcs_write(). The S6E8AA0 driver relies on the old asymmetric API and there's concern that moving to the new API may be less efficient. Provide a new function with the old semantics for those cases and make the S6E8AA0 driver use it instead. Reviewed-by:

This commit introduces a new function, mipi_dsi_create_packet(), which converts from a MIPI DSI message to a MIPI DSI packet. The MIPI DSI packet is as close to the protocol described in the DSI specification as possible and useful in drivers that need to write a DSI packet into a FIFO to send a message off to the peripheral.
