Hi Martin,

The AXP313a datasheet does not describe a register to change the DCDC switching frequency, and talks of it being fixed at 3 MHz. The BSP driver hints at a register being able to change that, but we haven't verified that, so leave that one out. It can be added later, if needed and/or required.The datasheet released by MangoPi says this isn't configurable. The thing that is configurable is spread-spectrum operation, and mode switching between fixed PWM and hybrid PFM/PWM. So just drop the DCDC frequency stuff and use the default code path.
You could get full datasheet of AXP313A here: https://github.com/YuzukiHD/YuzukiChameleon/blob/master/Datasheet/AXP313A_Datasheet_V1.0_cn.pdf Btw I'm working on AXP15060 support mostly based on your series. Best regards, Shengyu
