[PATCH v4 0/3] mailbox: Add APM X-Gene platform mailbox driver

[Duc Dang]

APM X-Gene SoC has a mailbox controller that provides
communication mechanism for X-Gene Arm64 cores to communicate
with X-Gene SoC's Cortex M3 (SLIMpro) processor.

X-Gene mailbox controller provides 8 mailbox channels, with
each channel has a dedicated interrupt line.

Changes since v3:
        - Rebase over v4.4
        - Remove 'id' in slimpro_mbox_chan structure
        - Remove functions that are only called once
        and fold them into the other callers
        - Remove void* pointer type cast
        - Relax the number of mailbox IRQs condition
	- Fix error and address comment in documentation
	(xgene-slimpro-mailbox.txt)

Changes since v2:
        - Rebase Feng's patch set over v4.3-rc5
        - Remove uneccessary 'inline' in function definition
        - Use module_platform_driver instead of subsys_initcall
        - Minor coding stype clean up

Changes since v1:
        - Add ACPI support
        - Use defines for reg offset
