Enable the Peripheral DMA controller (PDMA0) on the SpacemiT K1-based
Banana Pi F3 board by setting its status to "okay". This board-specific
configuration activates the PDMA controller defined in the SoC's base
device tree.

  Although this series is actively developed under Bananapi-f3 board
but it should work fine with jupiter board, so I'd suggest to enable
it too, thanks

I'd be glad to include the Jupiter board as well. Since I don't have Jupiter
hardware for testing, could someone with access verify it works before I
add it to the series?

Do you have any suggestion how to test? like if any test cases there?

I would assume it work fine on jupiter since it's a SoC level feature?
instead of board specific..

I am using the dmatest (CONFIG_DMATEST) for memory-to-memory
and using spi3 to test device-to-memory / memory-to-device.

Yeah, that's a SoC level device. I would say a boot test and some
basic mem-to-mem test should be enough.
