mfd: Explicitly include correct DT includes The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

mfd: Kill off set_irq_flags usage set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

mfd: core: Push irqdomain mapping out into devices Currently the MFD core supports remapping MFD cell interrupts using an irqdomain but only if the MFD is being instantiated using device tree and only if the device tree bindings use the pattern of registering IPs in the device tree with compatible properties. This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.

mfd: max8925: Move _IO resources out of ioport_ioresource The removal of mach/io.h from most ARM platforms also set the range of valid IO ports to be empty for most platforms when previously any 32 bit integer had been valid. This makes it impossible to add IO resources as the added range is smaller than that of the root resource for IO ports. Since we're not really using IO memory at all fix this by defining our own root resource outside the normal tree and make that the parent of all IO resources. This also ensures we won't conflict with read IO ports if we ever run on a platform which happens to use them.
