Hello,

From RM IMX8DQXPRM.pdf (Rev.0):

RM does not have any description for MIPI-CSI2's PHY_CTRL register.

Also, Linux BSP's source code too.

Could you please explain us meaning of each bit fields?

Best Regards,

Kazuma sasaki.

we don't have such document for every bits description, as I mentioned, customer can refer to the current bsp source code, define these bits the same value as linux driver defines.

you can find the mipi driver defined this register, and I confirmed that customer don't need to change this

mxc-mipi-csi2.c\imx8\platform\media\drivers - linux-imx - i.MX Linux kernel 

mxc-mipi-csi2.h\imx8\platform\media\drivers - linux-imx - i.MX Linux kernel

Dear Joan,

I appreciate your support.

I would like to know the meaning of all bit fields in PHY_CTRL register for porting mipi driver to RTOS.   

Because, all bit fields have not mentioned in iMX8X reference manual.

Best Regards,

Kazuma Sasaki.

Dear Joan,

Thank you for your feedback. 

We can not decide the setting value without bits description.

Could you please get these information from your expert team?

Best Regars,

Kazuma Sasaki.

I already consulted local expert team, they don't have such information either, and they don't think customer should care about this, they suggest customer set as bsp shows
