ARM: dts: MSM8660 remove flags from SPMI/MPP IRQs The Qualcomm SPMI GPIO and MPP lines are problematic: the are fetched from the main MFD driver with platform_get_irq() which means that at this point they will all be assigned the flags set up for the interrupts in the device tree. That is problematic since these are flagged as rising edge and an this point the interrupt descriptor is assigned a rising edge, while the only thing the GPIO/MPP drivers really do is issue irq_get_irqchip_state() on the line to read it out and to provide a .to_irq() helper for *other* IRQ consumers. If another device tree node tries to flag the same IRQ for use as something else than rising edge, the kernel irqdomain core will protest like this: type mismatch, failed to map hwirq-NN for <FOO>! Which is what happens when the device tree defines two contradictory flags for the same interrupt line. To work around this and alleviate the problem, assign 0 as flag for the interrupts taken by the PM GPIO and MPP drivers. This will lead to the flag being unset, and a second consumer requesting rising, falling, both or level interrupts will be respected. This is what the qcom-pm*.dtsi files already do. Switched to using the symbolic name IRQ_TYPE_NONE so that we get this more readable. This misconfiguration was caused by a copy/pasting the APQ8064 set-up, the latter has been fixed in a separate patch. Tested with one of the SPMI GPIOs: after this I can successfully request one of these GPIOs as falling edge from the device tree.
