I2C - SMBus core drivers use named interrupts to support smbus_alert.
As named interrupts are not available for ACPI based systems, it was
required to change the i2c bus controller driver if to use smbus alert.
These patches provide option for named interrupts in ACPI and make the
implementation similar to DT. This will enable use of interrupt named
'smbus-alert' in ACPI as well which will be taken during i2c adapter
register.

v3->v4:
* Removed device_irq_get_byname()
* Updates in comments and document.
v2->v3:
* Grammar/spelling corrections.
* Added description in function comments.
* Removed 'unlikely' from NULL check on 'name'
v1->v2:
* Added firmware guide documentation for ACPI named interrupts
* Updates in function description comments

Akhil R (3):
device property: Add fwnode_irq_get_byname
docs: firmware-guide: ACPI: Add named interrupt doc
i2c: smbus: Use device_*() functions instead of of_*()
