Hi community,

 

I have a question about i.MX6DQ Linux BSP.

Please see arch/arm/boot/dts/imx6q.dtsi in L3.10.17_1.0.0-ga.

The VDD_ARM_CAP voltage when 792MHz is set to 1.150V in line 33.

Next, please see same file in L3.10.53_1.1.0-ga, it is set  to 1.175V in line 33.

 

Would you let me know why the setting was changed?

To add some margine from i.MX6DQ VDD_ARM_CAP min value (1.1.50V @ up to 792MHz)?

 

 

Best Regards,

Satoshi Shimoda
