Subject: [PATCH v2 0/7] drm/mipi-dsi: simplify MIPI DSI init/cleanup even
 more

Follow the example of mipi_dsi_generic_write_multi(),
mipi_dsi_dcs_write_buffer_multi(), mipi_dsi_generic_write_seq_multi()
and mipi_dsi_dcs_write_seq_multi(). Define _multi variants for several
other common MIPI DSI functions and use these functions in the panel
code.

This series also includes a fix for the LG SW43408. If the proposed
approach is declined, the fix will be submitted separately.

Depends:
