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_*() Documentation/firmware-guide/acpi/enumeration.rst | 38 +++++++++++++++++++++++ drivers/base/property.c | 35 +++++++++++++++++++++ drivers/i2c/i2c-core-base.c | 2 +- drivers/i2c/i2c-core-smbus.c | 10 +++--- drivers/i2c/i2c-smbus.c | 2 +- include/linux/i2c-smbus.h | 6 ++-- include/linux/property.h | 3 ++ 7 files changed, 86 insertions(+), 10 deletions(-)
