Subject[PATCH v4 0/7] I2C IRQ Probe Improvements
This series attempts to align as much IRQ handling into the
probe path as possible. Note that I don't have a great setup
for testing these patches so they are mostly just build tested
and need careful review and testing before any of them are

The series brings the ACPI path inline with the way the device
tree path handles the IRQ entirely at probe time. However,
it still leaves any IRQ specified through the board_info as
being handled at device time. In that case we need to cache
something from the board_info until probe time, which leaves
any alternative solution with something basically the same as
the current handling although perhaps caching more stuff.


See previous discussions:

Charles Keepax (7):
i2c: core: Allow whole core to use i2c_dev_irq_from_resources
i2c: acpi: Use available IRQ helper functions
i2c: acpi: Factor out getting the IRQ from ACPI
i2c: core: Make i2c_acpi_get_irq available to the rest of the I2C core
i2c: core: Move ACPI IRQ handling to probe time
i2c: core: Move ACPI gpio IRQ handling into i2c_acpi_get_irq
i2c: core: Tidy up handling of init_irq
