This is fourth version of the series. I've based these on top of Rafael's
"simplify glueing ACPI handles to physical nodes" available from here:
https://lkml.org/lkml/2012/11/19/588
There is a dependency to linux-pm tree and to the above patches so I
propose to merge these via that same tree. Subsystem maintainers, can you
ack these if you think that they are a suitable shape?
Changes to v3:
- simplify acpi_gpiochip_find()
- acpi_spi/i2c_add_resource() uses acpi_dev_resource_interrupt()
directly instead of first checking the resource type
- acpi_spi/i2c_add_device() calls acpi_dev_free_resource_list()
immediately after walking the resources and get rid of
fail_put_dev label.
Changes to v2:
- drop the ACPI ->find_device() glue magic in preference of the new
simplified mechanism where we just assign the ACPI handle
- correct the IRQ resource handling to take the first resource and
skip the rest
- moved declaration of acpi_i2c_register_devices() to i2c.h instead
of having a separate header for a single function
Changes to the original version:
[gpio]
- CONFIG_GPIO_ACPI instead of CONFIG_ACPI_GPIO
- removed redundant test in acpi_gpiochip_find()
[spi and i2c]
- switched to use ACPI centralized _CRS evaluation framework
introduced by Rafael
- dropped request_module() call
- dropped the acpi_enumerate_spi/i2c_device()
- added required includes and dropped <linux/acpi.h> from
acpi_i2c.h
Thanks.
