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.
