i.MX6DL: Max IPU Clock

Hello Champs,

 

In LTIB verson of u-boot, ipu1_clk is set 260MHz in default.

However in the Yocto u-boot, it is defined as 198MHz.

 

#ifdef CONFIG_MX6DL                                                       

#define CONFIG_IPUV3_CLK 198000000

#else

#define CONFIG_IPUV3_CLK 264000000

#endif

 

Is this because ipu_clk was turned out actually limited to 198MHz in MX6DL?

Or just because a result of clock tree changes in Yocto u-boot?

 

BR,

N.S.
