Hi everyone, I'm working on adding the support for the AT91SAM9M10G45-EK board from Atmel for the at91_adc driver I previously posted, and I encounter some weird issue here. When calling the iio_allocate_trigger (http://lxr.free-electrons.com/source/drivers/staging/iio/industrialio-trigger.c?a=arm#L421) from my driver on the G45, it returns ENOMEM, while on the AT91SAM9G20-EK board, it works perfectly. Digging a bit into it, it seems that the call to irq_alloc_descs is returning the error (the value of CONFIG_IIO_CONSUMERS_PER_TRIGGER is 2 in my configuration, which seems pretty reasonable and is the default value anyway), which is itself getting that return value from irq_expand_nr_irqs. Here, I'm left confused, I don't know this part of the kernel anymore, and most importantly, it seems to be pretty-much arch-independant, while the nature of my issue seems really platform-dependant. Do you have any clue of what's going on here ?
