pinctrl/nomadik: use zero as default irq_start 2012-10-23T09:52:19+00:00 Linus Walleij linus.walleij@linaro.org 2012-10-23T07:50:17+00:00 832b6cdf72fdc32cacba242a749402d28f4648f0 The irqdomain semantics were supposed to be such that a linear domain would be used if the passed first_irq was zero or negative, but I got it wrong so only passing zero as first_irq will work properly. Well, zero is NO_IRQ these days so let's pass zero. The semantics of irqdomain_add_simple() will be fixed in a separate patch.

pinctrl/nomadik: use irq_create_mapping() 2012-10-23T08:33:39+00:00 Linus Walleij linus.walleij@linaro.org 2012-10-19T15:06:54+00:00 268300be0e1a0b06582af55251294b268c3d4654 Since in the DT case, the linear domain path will not allocate descriptors for the IRQs, we need to use irq_create_mapping() for mapping hwirqs to Linux IRQs, so these descriptors get created on-the-fly in this case. ChangeLog v1->v2: - Just use irq_create_mapping() in the .to_irq function since this is called before unmasking or enabling any interrupt lines, so irq_find_mapping() should be sufficient for the IRQ handler function.
