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.

v1->v2:
  * Added firmware guide documentation for ACPI named interrupts
  * Updates in function description comments

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

Most of my comments are regarding spelling and documentation.
The code looks almost good enough. That said, if maintainers will be
okay, I'm sure the next version will be upstream-ready.

Thanks!
