Merge tag 'irqdomain-for-linus' of git://git.secretlab.ca/git/linux
Pull irqdomain refactoring from Grant Likely:
"This is the long awaited simplification of irqdomain. It gets rid of
the different types of irq domains and instead both linear and tree
mappings can be supported in a single domain. Doing this removes a
lot of special case code and makes irq domains simpler to understand
overall"
* tag 'irqdomain-for-linus' of git://git.secretlab.ca/git/linux:
irq: fix checkpatch error
irqdomain: Include hwirq number in /proc/interrupts
irqdomain: make irq_linear_revmap() a fast path again
irqdomain: remove irq_domain_generate_simple()
irqdomain: Refactor irq_domain_associate_many()
irqdomain: Beef up debugfs output
irqdomain: Clean up aftermath of irq_domain refactoring
irqdomain: Eliminate revmap type
irqdomain: merge linear and tree reverse mappings.
irqdomain: Add a name field
irqdomain: Replace LEGACY mapping with LINEAR
irqdomain: Relax failure path on setting up mappings
