Subject[PATCH v3 0/3] Add Qualcomm MPM irqchip driver support
Date
It updates IRQCHIP_PLATFORM_DRIVER infrastructural to pass
platform_device pointer to init_cb. On top of that, add DT binding
and driver support for Qualcomm MPM (MSM Power Manager) interrupt
controller.

Changes for v3:
- Support module build
- Use relaxed accessors
- Add barrier call to ensure MMIO write completes
- Use d->chip_data to pass driver private data
- Use raw spinlock
- USe BIT() for bit shift
- Create a single irq domain to cover both types of MPM pins
- Call irq_resolve_mapping() to find out Linux irq number
- Save the use of ternary conditional operator and use switch/case for
.irq_set_type call
- Drop unnecessary .irq_disable hook
- Align qcom_mpm_chip and qcom_mpm_ops members vertically
- Use helper irq_domain_translate_twocell()
- Move mailbox requesting forward in probe function
- Improve the documentation on qcm2290_gic_pins[]
- Use IRQCHIP_PLATFORM_DRIVER infrastructural
- Use cpu_pm notifier instead of .suspend_late hook to write MPM for
sleep, so that MPM can be set up for both suspend and idle context.
The TIMER0/1 setup is currently omitted for idle use case though,
as I haven't been able to successfully test the idle context.
