At least the comment is interesting about the different EVK board versions: mine is v1.6, which confirms the connection of the ID pin to the GPIO1_11 pin. This also means that old boards have a connection from the IRQ pin to GPIO1_11, and for these older boards the DTS is probably Ok as it is? How can we support both configurations? Hugo.
