IMX8M MIPI-CSI Host Controller: send level?

Question asked by John Obendorfer on Jan 25, 2019

In the driver mxc-mipi-csi2_yav.c, there's a point the function mxc_mipi_csi2_hc_config() where a parameter called "send level" is written to an undocumented register at offset 0188H from the base of the host controller register file.

 

The value 1 is also written to an undocumented register at offset 0180H and 0184H.

 

Can anyone tell me what these settings do, and how they were derived?
