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
