Revert "of: Fix premature bootconsole disable with 'stdout-path'"

2015-03-19T13:46:54Z

This reverts commit 2fa645cb2703d9b3786d850db815414dfeefa51d. The assumption that at least 1 preferred console will be registered when the stdout-path property is set is invalid, which can result in _no_ consoles. Signed-off-by: Peter Hurley Signed-off-by: Rob Herring

of: handle both '/' and ':' in path strings

2015-03-19T13:42:43Z

Commit 106937e8ccdc ("of: fix handling of '/' in options for of_find_node_by_path()") caused a regression in OF handling of stdout-path. While it fixes some cases which have '/' after the ':', it breaks cases where there is more than one '/' *before* the ':'. For example, it breaks this boot string stdout-path = "/rdb/serial@f040ab00:115200"; So rather than doing sequentialized checks (first for '/', then for ':'; or vice versa), to get the correct behavior we need to check for the first occurrence of either one of them. It so happens that the handy strcspn() helper can do just that.

Ensure proper handling of paths with appended options (after ':'), where those options may contain a '/'. Fixes: 7914a7c5651a ("of: support passing console options with stdout-path") Reported-by: Peter Hurley Signed-off-by: Leif Lindholm Cc: # 3.19 Signed-off-by: Rob Herring

of: Fix premature bootconsole disable with 'stdout-path'

2015-03-10T15:27:21Z

Support for devicetree serial consoles via 'stdout-path' causes bootconsoles to be disabled when the vt dummy console loads, since there is no preferred console (the preferred console is not added until the device is probed). Ensure there is at least a preferred console, even if never matched. Requires: "console: Fix console name size mismatch" Cc: Andrew Morton Signed-off-by: Peter Hurley Signed-off-by: Rob Herring

Make of_property_read_u64_array() available for modules as well. This was missing from the patch which originally added the function. Signed-off-by: Sakari Ailus Signed-off-by: Rob Herring

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.
