It connects the two SPI controllers of the SoC, one is a host and one is a target, so it behave as an SPI target on one side and as an SPI host on the other. The trivial devices bindings seems to be dedicated to devices, thus not for SPI hosts. Do I need a dedicated binding or did I miss something I could use for a trivial spidev slave? > > Best regards, > Krzysztof Best regards, -- Benoît Monin, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
