Change the DDRC_DRAMTMG registers

Hi all

 

We are changing RAM access frequency from 533 MHz to 133 MHz.
In that case, I also want to change DDRC_DRAMTMG together.


We want to increase access efficiency by setting WL and RL to optimal values.

I am trying to refer to the Linux lpddr3_freq_imx.s code, but there was no description about DDRC_DRAMTMG.
I checked the datasheet, but I could not find a procedure to change dynamically.

 

Please tell me how to change it.
