Hi.
I am porting the mipi dsi panel driver.
The cpu is imx8mq.
The driver code is using "panel-sn65dsix.c"
I have confirmed that it works in Oreo(imx_o8.1.0_1.3.0, kernel version is 4.9.78)
But, I need to upgrade the kernel version.
Currently, I am downloading "imx_o8.1.0_2.0.0" and working on porting it.(kernel version is 4.14.98)
However, driver porting failed.
The driver "sn65_panel_prove" seem to work, but it stop in the "sn65_panel_get_modes".
As a result of checking the kernel log, there is
"[drm] Cannot find any crtc or sizes", "[drm] found mode none"
I think the drm sequence is different depending on the kernel version.
I attach the driver code and device tree file, I am using.
I need your help!!!
Thankyou!!
