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. v4->v5: * Include property.h in headers of i2c-smbus and i2c-smbus-core 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_*() Documentation/firmware-guide/acpi/enumeration.rst | 39 +++++++++++++++++++++++ drivers/base/property.c | 29 +++++++++++++++++ drivers/i2c/i2c-core-base.c | 2 +- drivers/i2c/i2c-core-smbus.c | 11 ++++--- drivers/i2c/i2c-smbus.c | 5 +-- include/linux/i2c-smbus.h | 6 ++-- include/linux/property.h | 1 + 7 files changed, 82 insertions(+), 11 deletions(-) -- 2.7.4
