Fri Nov 1 13:35:53 CET 2013
Second version of the set that changes I2C and SPI slave device names
to be generated from stable ACPI device names on ACPI 5 based systems
instead of using bus numbers which could change.
Slave device name change goes as
"x-00yz" -> "i2c-INTABCD:ij"
"spix.y" -> "spi-INTABCD:ij"
This version adds patch to include/acpi/acpi_bus.h that allow us to
remove #if IS_ENABLED(CONFIG_ACPI) checks that were added in the
Set goes on top linux-pm/linux-next commit e56b4d2.
First version here:
Jarkko Nikula (3):
ACPI: Expose struct acpi_device and acpi_bus_get_device() to non-ACPI
i2c: Use stable dev_name for ACPI enumerated I2C slaves
spi: Use stable dev_name for ACPI enumerated SPI slaves
