Merge branch 'device-properties'
* device-properties: device property: avoid allocations of 0 length device property: the secondary fwnode needs to depend on the primary device property: add spaces to PROPERTY_ENTRY_STRING macro include/linux/property.h: fix build issues with gcc-4.4.4 i2c: designware: Convert to use unified device property API mfd: intel-lpss: Pass HSUART configuration via properties mfd: intel-lpss: Pass SDA hold time to I2C host controller driver mfd: intel-lpss: Add support for passing device properties mfd: core: propagate device properties to sub devices drivers driver core: Do not overwrite secondary fwnode with NULL if it is set driver core: platform: Add support for built-in device properties device property: Take a copy of the property set device property: Fallback to secondary fwnode if primary misses the property device property: return -EINVAL when property isn't found in ACPI device property: improve readability of macros device property: helper macros for property entry creation device property: keep single value inplace device property: refactor built-in properties support device property: rename helper functions device property: always check for fwnode type
