MIPI DSI PHY timing registers on i.MX7D

Hi all,


We're using a MIPI DSI panel (Ilitek ILI9806E controller) connected to a i.MX7D based custom board.
We added support for our display in the mipi_dsi_samsung driver, but we don't fully understand how to adjust the following registers:




The Reference Manual does not report much information on these registers. The commit that added those timings for the Truly display also doesn't disclose much about them.


Is there any tool/document explaining how to figure out these register values? What units are they?


Thank you for your support,
