2017-08-01device property: Fix usecount for of_graph_get_port_parent()Tony Lindgren1-2/+15
Fix inconsistent use of of_graph_get_port_parent() where asoc_simple_card_parse_graph_dai() does of_node_get() before calling it while other callers do not. We can fix this by not trashing the node passed to of_graph_get_port_parent(). Let's also make sure the callers have correct refcounts and remove related incorrect of_node_put() calls for of_for_each_phandle as that's done by of_phandle_iterator_next() except when we break out of the loop early. Let's fix both issues with a single patch to avoid kobject refcounts getting messed up more if two patches are merged separately. Otherwise strange issues can happen caused by memory corruption caused by too many kobject_del() calls such as: BUG: sleeping function called from invalid context at kernel/locking/mutex.c:747 ... (___might_sleep) (__mutex_lock) (mutex_lock_nested) (kernfs_remove) (kobject_del) (kobject_put) (of_get_next_parent) (of_graph_get_port_parent) (asoc_simple_card_parse_graph_dai [snd_soc_simple_card_utils]) (asoc_graph_card_probe [snd_soc_audio_graph_card]) Fixes: 0ef472a973eb ("of_graph: add of_graph_get_port_parent()") Fixes: 2692c1c63c29 ("ASoC: add audio-graph-card support") Fixes: 1689333f8311 ("ASoC: simple-card-utils: add asoc_simple_card_parse_graph_dai()") Signed-off-by: Tony Lindgren <tony@atomide.com> Reviewed-by: Rob Herring <robh@kernel.org> Tested-by: Antonio Borneo <borneo.antonio@gmail.com> Tested-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2017-06-27vsprintf: Add %p extension "%pOF" for device treePantelis Antoniou2-1/+61
90% of the usage of device node's full_name is printing it out in a kernel message. However, storing the full path for every node is wasteful and redundant. With a custom format specifier, we can generate the full path at run-time and eventually remove the full path from every node. For instance typical use is: pr_info("Frobbing node %s\n", node->full_name); Which can be written now as: pr_info("Frobbing node %pOF\n", node); '%pO' is the base specifier to represent kobjects with '%pOF' representing struct device_node. Currently, struct device_node is the only supported type of kobject. More fine-grained control of formatting includes printing the name, flags, path-spec name and others, explained in the documentation entry. Originally written by Pantelis, but pretty much rewrote the core function using existing string/number functions. The 2 passes were unnecessary and have been removed. Also, updated the checkpatch.pl check. The unittest code was written by Grant Likely.

2017-05-30iommu/of: Ignore all errors except EPROBE_DEFERSricharan R1-2/+2
While deferring the probe of IOMMU masters, xlate and add_device callbacks called from of_iommu_configure can pass back error values like -ENODEV, which means the IOMMU cannot be connected with that master for real reasons. Before the IOMMU probe deferral, all such errors were ignored. Now all those errors are propagated back, killing the master's probe for such errors. Instead ignore all the errors except EPROBE_DEFER, which is the only one of concern and let the master work without IOMMU, thus restoring the old behavior. Also make explicit that of_dma_configure handles only -EPROBE_DEFER from of_iommu_configure.

2017-05-16of: irq: use of_irq_get() in of_irq_to_resource()Thomas Petazzoni1-1/+4
of_irq_to_resource() currently uses irq_of_parse_and_map() to translate a DT interrupt specification into a Linux virtual interrupt number. While this works in most cases, irq_of_parse_and_map() doesn't properly handle the case where the interrupt controller is not yet available (due to deferred probing for example). So instead, use of_irq_get(), which is implemented exactly like irq_of_parse_and_map(), with the exception that if the interrupt controller is not yet available, it returns -EPROBE_DEFER. Obviously, we also handle this error and bail out from of_irq_to_resource() when of_irq_get() returns an error. This allows to avoid silly error messages at boot time caused by irq_create_of_mapping() when the interrupt controller is not available: [ 0.153168] irq: no irq domain found for /ap806/config-space@f0000000/interrupt-controller@3f0100 !
