This series removes the unintuitive mipi_dsi_generic_write_seq() macro and related mipi_dsi_generic_write_chatty() method from the drm subsystem. This is in accordance with a TODO item from Douglas Anderson in the drm subsystem documentation. Tejas Vipin (among others) has largely spearheaded this effort up until now, converting MIPI panel drivers one at a time.
The second patch of the series removes the last remaining references to mipi_dsi_generic_write_seq() in the jdi-lpm102a188a driver and updates the driver to use the undeprecated _multi variants of MIPI functions. It fixes a bug in the driver's unprepare function and cleans up duplicated code using the new mipi_dsi_dual macro introduced in the first patch. changes to v3: - Define new mipi_dsi_dual macro in drm_mipi_dsi.h to reduce code duplication. - Fix bug in lpm102a188a panel driver's unprepare function which causes it to return a nonsensical value. - Make lpm102a188a panel driver's unprepare function send "display off" and "enter sleep mode" commands to both serial interfaces regardless of whether an error occurred when sending the last command. changes to v2: - Remove all usages of deprecated MIPI functions from jdi-lpm102a188a driver instead of just mipi_dsi_generic_write_seq(). - Update TODO item in drm documentation instead of removing it entirely.
