irqchip/irq-brcmstb-l2: Add write memory barrier before exit

irqchip/irq-brcmstb-l2: Add write memory barrier before exit
commit b0344d6854d25a8b3b901c778b1728885dd99007 upstream.
It was observed on Broadcom devices that use GIC v3 architecture L1 interrupt controllers as the parent of brcmstb-l2 interrupt controllers that the deactivation of the parent interrupt could happen before the brcmstb-l2 deasserted its output. This would lead the GIC to reactivate the interrupt only to find that no L2 interrupt was pending. The result was a spurious interrupt invoking handle_bad_irq() with its associated messaging. While this did not create a functional problem it is a waste of cycles.
The hazard exists because the memory mapped bus writes to the brcmstb-l2 registers are buffered and the GIC v3 architecture uses a very efficient system register write to deactivate the interrupt.
Add a write memory barrier prior to invoking chained_irq_exit() to introduce a dsb(st) on those systems to ensure the system register write cannot be executed until the memory mapped writes are visible to the system.

irqchip: 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.

irqchip/irq-brcmstb-l2: Set IRQ_LEVEL for level triggered interrupts
When support for the level triggered interrupt controller flavor was added with c0ca7262088e, we forgot to update the flags to be set to contain IRQ_LEVEL. While the flow handler is correct, the output from /proc/interrupts does not show such interrupts as being level triggered when they are, correct that.

irqchip/bcm: Restore registration print with %pOF
It is useful to print which interrupt controllers are registered in the system and which parent IRQ they use, especially given that L2 interrupt controllers do not call request_irq() on their parent interrupt and do not appear under /proc/interrupts for that reason.
We used to print the base register address virtual address which had little value, use %pOF to print the path to the Device Tree node which maps to the physical address more easily and is what people need to troubleshoot systems.

irqchip/brcmstb-l2: Add support for the BCM7271 L2 controller
Add the initialization of the generic irq chip for the BCM7271 L2 interrupt controller. This controller only supports level interrupts and uses the "brcm,bcm7271-l2-intc" compatibility string.

irqchip/brcmstb-l2: Abstract register accesses
Added register block offsets to the brcmstb_l2_intc_data structure for the status and mask registers to support reading the active interupts in an abstracted way. It seems like an irq_chip method should have been provided for this, but it's not there yet.
Abstracted the implementation of the handler, suspend, and resume functions to not use any hard coded register offsets.

irqchip/brcmstb-l2: Remove some processing from the handler
Saving the generic chip pointer in the brcmstb_l2_intc_data prevents the need to call irq_get_domain_generic_chip(). Also don't need to save parent_irq and base there since local variables in the brcmstb_l2_intc_of_init() function are just as good.
The handle_edge_irq flow or chained_irq_enter takes care of the acknowledgment of the interrupt so it is redundant to clear it in brcmstb_l2_intc_irq_handle().
irq_linear_revmap() is a fast path equivalent of irq_find_mapping() that is appropriate to use for domain controllers of this type.
Defining irq_mask_ack is slightly more efficient than just implementing irq_mask and irq_ack separately.

irqchip: brcmstb-l2: Define an irq_pm_shutdown function
The Broadcom STB platforms support S5 and we allow specific hardware wake-up events to take us out of this state. Because we were not defining an irq_pm_shutdown() function pointer, we would not be correctly masking non-wakeup events, which would result in spurious wake-ups from sources that were not explicitly configured for wake-up.

IRQCHIP: brcmstb-l2: don't clear wakeable interrupts at init time
Wakeable interrupts might be pending at boot/init time, because wakeup interrupts might have triggered a resume from S5. So don't clear such wakeups.
This means that any driver which requests a wakeable interrupt bit should be prepared to handle an interrupt as soon as they call request_irq(). (This is technically already the correct development practice, but some drivers probably expect not to receive interrupts until they have performed some I/O.)
