This commit moves the driver to drivers/pwm and converts it to the new PWM framework. In order for this to work properly, register the PWM as child of the multi-function TWL6030 device.

Before the AB8500 had its own IRQ domain, the IRQ handler would take the fired local IRQ (hwirq) and add it to the irq_base to convert it to an IRQ number which Linux would understand (virq). However, the IRQ base is not always used anymore since we can make use of Linear domains. It's better to use the AB8500 hwirq -> virq mapping helper function to convert them instead. That's what we do here. Signed-off-by: NLee Jones <lee.jones@linaro.org> Acked-by: NLinus Walleij <linus.walleij@linaro.org> Signed-off-by: NSamuel Ortiz <sameo@linux.intel.com>

MFD core now takes care of HWIRQ <-> VIRQ mapping, so the helper ab8500_irq_get_virq() is no longer used by ab8500 subordinate devices to obtain a Linux wide Virtual IRQ.

The ICH chips have their GPIO pins organized in 2 or 3 independent groups of 32 GPIO pins. It can happen that the ACPI BIOS wants to make use of pins in one group, preventing the OS to access these. This does not prevent the OS from accessing the other group(s). This is the case for example on my Asus Z8NA-D6 board. The ACPI BIOS wants to control GPIO 18 (group 1), while I (the OS) need to control GPIO 52 and 53 (group 2) for SMBus multiplexing. So instead of checking for ACPI resource conflict on the whole I/O range, check on a per-group basis, and consider it a success if at least one of the groups is available for the OS to use.

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.
