| Subject | [PATCH v4 0/3] mailbox: Add APM X-Gene platform mailbox driver |
| Message-ID | <qRppw-6Tt-3@gated-at.bofh.it> |
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
