Hi, This series brings couple of useful GPIO related properties from Device Tree to ACPI _DSD device properties:
- Names for GPIO lines - GPIO hogging - Holes in GPIO property lists We are using these to get Intel Galileo better supported in the mainline kernel (but these may be useful for other boards as well). For example SPI chip select on Galileo is connected to a GPIO line so we need to be able to describe it in ACPI, and at the same time allow native chip selects. GPIO hogging can be used to set initial state of certain GPIOs available on the headers regardless of the BIOS settings (which may be wrong as it knows nothing about which devices have been connected). The previous version can be found here: http://www.spinics.net/lists/linux-acpi/msg69385.html Changes from v1: - Drop patch [1/5] as it has been applied already. - Move patch [4/5] to be the first. - Rename acpi_data_get_property_reference() to __acpi_node_get_property_reference(). - Drop acpi_node_get_property_reference() as it is not necessary anymore. - Add static inline wrapper acpi_node_get_property_reference() that calls the previous passing MAX_ACPI_REFERENCE_ARGS to support existing drivers.
