About calculation of mipi clock in i.MX6DQ.

[keitanagashima]

Hi All,

I have a question about mipi clock.

Refer to document in below link.

https://community.freescale.com/docs/DOC-94312#comment-29669

How should you calculate the OV5640's MIPI clock (= 849MHz)?

======

-     mipi_csi2_write(info, 0x00000014, CSI2_PHY_TST_CTRL1);//ov5640 output clk

&

The range and the exact value when ref_clock is 27M are showed as below:

//  800-850MHz  :0x14   //849Mhz

======

Best Regards,

Keita

Hello, Keita !

  Sorry, there is no detailed information about clock settings (programming
internal MIPI CSI-2 DPHY registers), because of third party agreement.

For some details :

MIPI CSI and IPU questions

Have a great day,
Yuri
