Pull devicetree changes from Grant Likely: "Lots of activity in the devicetree code for v3.18. Most of it is related to getting all of the overlay support code in place, but there are other important things in there. Highlights: - OF_RECONFIG notifiers for SPI, I2C and Platform devices. Those subsystems can now respond to live changes to the device tree. - CONFIG_OF_OVERLAY method for applying live changes to the device tree - Removal of the of_allnodes list. This used to be used to iterate over all the nodes in the device tree, but it is unnecessary because the same thing can be done by iterating over the list of child pointers. Getting rid of of_allnodes saves some memory and avoids the possibility of of_allnodes being sorted differently from the child lists. - Support for retrieving original DTB blob via sysfs. Needed by kexec. - More unittests - Documentation and minor bug fixes" * tag 'devicetree-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/glikely/linux: (42 commits) of: Delete unnecessary check before calling "of_node_put()" of: Drop ->next pointer from struct device_node spi: Check for spi_of_notifier when CONFIG_OF_DYNAMIC=y of: support passing console options with stdout-path of: add optional options parameter to of_find_node_by_path() of: Add bindings for chosen node, stdout-path of: Remove unneeded and incorrect MODULE_DEVICE_TABLE ARM: dt: fix up PL011 device tree bindings of: base, fix of_property_read_string_helper kernel-doc of: remove select of non-existant OF_DEVICE config symbol spi/of: Add OF notifier handler spi/of: Create new device registration method and accessors i2c/of: Add OF_RECONFIG notifier handler i2c/of: Factor out Devicetree registration code of/overlay: Add overlay unittests of/overlay: Introduce DT overlay support of/reconfig: Add OF_DYNAMIC notifier for platform_bus_type of/reconfig: Always use the same structure for notifiers of/reconfig: Add debug output for OF_RECONFIG notifiers of/reconfig: Add empty stubs for the of_reconfig methods ...

of: support passing console options with stdout-path

2014-12-03T23:12:37Z

Support specifying console options (like with console=ttyXN,) by appending them to the stdout-path property after a separating ':'. Example: stdout-path = "uart0:115200"; Signed-off-by: Leif Lindholm [grant.likely: minor rework to shorten the diffstat] Signed-off-by: Grant Likely

of: add optional options parameter to of_find_node_by_path()

2014-12-03T23:12:36Z

Update of_find_node_by_path(): 1) Rename function to of_find_node_opts_by_path(), adding an optional pointer argument. Provide a static inline wrapper version of of_find_node_by_path() which calls the new function with NULL as the optional argument. 2) Ignore any part of the path beyond and including the ':' separator. 3) Set the new provided pointer argument to the beginning of the string following the ':' separator. 4: Add tests.

of: base, fix of_property_read_string_helper kernel-doc

2014-11-27T17:21:21Z

It referenced of_property_read_string_util whereas the function name is of_property_read_string_helper. Introduced in a87fa1d81a9fb5e9adca9820e16008c40ad09f33 (of: Fix overflow bug in string property parsing functions). Found out when reviewing the stable 3.12 queue.

of: Change of_device_is_available() to return bool

2014-11-18T17:32:55Z

This function can only return true or false; using a bool makes it more obvious to the reader. Signed-off-by: Kevin Cernekee Signed-off-by: Grant Likely

of: Fix of_device_is_compatible() comment

2014-11-18T17:32:07Z

This function passes back a value from __of_device_is_compatible(), which returns a score in the range 0..11, not a bool. Signed-off-by: Kevin Cernekee Signed-off-by: Grant Likely

Driver core: Unified device properties interface for platform firmware

2014-11-04T20:58:21Z

Add a uniform interface by which device drivers can request device properties from the platform firmware by providing a property name and the corresponding data type. The purpose of it is to help to write portable code that won't depend on any particular platform firmware interface. The following general helper functions are added: device_property_present() device_property_read_u8() device_property_read_u16() device_property_read_u32() device_property_read_u64() device_property_read_string() device_property_read_u8_array() device_property_read_u16_array() device_property_read_u32_array() device_property_read_u64_array() device_property_read_string_array() The first one allows the caller to check if the given property is present. The next 5 of them allow single-valued properties of various types to be retrieved in a uniform way. The remaining 5 are for reading properties with multiple values (arrays of either numbers or strings). The interface covers both ACPI and Device Trees. This change set includes material from Mika Westerberg and Aaron Lu.
