Subject: [PATCH v2 0/3] Enable named interrupt smbus-alert for ACPI
Date: Wed, 12 Jan 2022 19:44:19 +0530 [thread overview]
Message-ID: <1641996862-26960-1-git-send-email-akhilrajeev@nvidia.com> (raw)
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_*()
