get from dts property using function, and it should be set in soc Kconfig.defconfig file, not by a board

This is the way other boards configure the clock cycles. It's also part of an example here: Board Porting Guide

that documentation is very outdated and needs to be fixed, but this also needs to be fixed, this Kconfig needs to come from a dts value and in the soc Kconfig.defconfig file

I would rather have this changed in a different PR. It should be consistent for all board. And then the documentation should be updated accordingly.

nothing new to be added with the old style, so if the old style remains in this PR then this PR will remain nacked

@LukasWoodtli is there a reason why you still want to keep this as a Draft PR? |

From what I see here: https://www.silabs.com/documents/public/data-sheets/efm32tg-datasheet.pdf
Flash size is only 32 kB and ram size is 4kB

GPIO ODD interrupt is 9
btw I think the format should now more look like "<1 2>, <9 2>" ? but I don't know if there is a particularity for gpio.
