No issue to connect such kind of charger to power the DK1 or DK2, it will always be providing 5V until the target try to negotiate higher voltage using USB PowerDelivery protocol (or other proprietary protocols like QC).
For sure we do not ask for more than 5V on our boards, as you see, it is not supported !
Be sure it is USB Type-C compliant providing at least 5V 3A (15W).
If 5V 3A capabilities is not detected at board startup, it will work, but you will have warning message (on ST-LINK VCP console) and red led blink showing the limitation (see on wiki, snapshot below).
This is a warning as, for a too weak charger, you can experience voltage drop and ultimately a board reset (e.g. if you connect some power hungry devices on USB Type-A ports).
Without any external connections the STM32MP157C-DK2 should be within a 5V 0.9A envelope guaranteed by USB Type-C standard (i.e. a charger or a computer with a Type-C socket). Warning than usually a computer/charger with a Type-A socket, so using a Type-A <-> TypeC cable is usually detected as 500mA.
