Pantelis, Frank,
A quick question about the state of devicetree overlays. There don't seem to be many in-kernel overlay users (rcar and fpga only?). Does it make sense for new projects to use them?
My situation is this: I have hardware which consists of several modules. Knowledge about the type and location of these modules is located in an on-board eeprom.
So now I need to assemble a devicetree, by puzzling various 'blobs' together. This could be done in the bootloader, but also by a rcar-like driver, which queries the eeprom and inserts devicetree fragments/overlays into a live kernel.
A couple of questions: - are devicetree overlays here to stay? (given that there are 2 in-kernel users) - does it make sense to solve the modular devicetree problem in a rcar-like fashion? - is there perhaps a more canonical / idiomatic way to solve this?
Sven
