of: remove redundant memset in overlay

2017-01-09T20:21:23+00:00

memset in of_build_overlay_info is redundant, the ovinfo has been zeroed in of_fill_overlay_info when error. Signed-off-by: YiPing Xu Signed-off-by: Rob Herring

of: drop duplicate headers

2017-01-04T20:01:28+00:00

Drop duplicate headers string.h and of_platform.h. Signed-off-by: Geliang Tang Signed-off-by: Rob Herring

of/overlay: add of overlay notifications

2016-11-10T16:03:35+00:00

This patch add of overlay notifications. When DT overlays are being added, some drivers/subsystems need to see device tree overlays before the changes go into the live tree. This is distinct from reconfig notifiers that are post-apply or post-remove and which issue very granular notifications without providing access to the context of a whole overlay. The following 4 notificatons are issued: OF_OVERLAY_PRE_APPLY OF_OVERLAY_POST_APPLY OF_OVERLAY_PRE_REMOVE OF_OVERLAY_POST_REMOVE In the case of pre-apply notification, if the notifier returns error, the overlay will be rejected. This patch exports two functions for registering/unregistering notifications: of_overlay_notifier_register(struct notifier_block *nb) of_overlay_notifier_unregister(struct notifier_block *nb) The of_mutex is held during these notifications. The notification data includes pointers to the overlay target and the overlay: struct of_overlay_notify_data { struct device_node *overlay; struct device_node *target; }; Signed-off-by: Alan Tull Acked-by: Rob Herring Acked-by: Moritz Fischer Signed-off-by: Greg Kroah-Hartman

of: use pr_fmt prefix for all console printing

2016-07-18T21:57:42+00:00

Clean-up all the DT printk functions to use common pr_fmt prefix. Some print statements such as kmalloc errors were redundant, so just drop those. Cc: Frank Rowand Cc: Pantelis Antoniou Reviewed-by: Frank Rowand Signed-off-by: Rob Herring

drivers/of: Export OF changeset functions

2016-01-13T22:10:37+00:00

The PowerNV PCI hotplug driver is going to use the OF changeset to manage the changed device sub-tree. This exports those OF changeset functions for that. Signed-off-by: Gavin Shan Acked-by: Wolfram Sang Tested-by: Wolfram Sang Signed-off-by: Rob Herring

of/overlay: add missing of_node_put

2015-10-22T14:35:51+00:00

for_each_child_of_node performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. A simplified version of the semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // @@ expression root,e; local idexpression child; @@ for_each_child_of_node(root, child) { ... when != of_node_put(child) when != e = child ( return child; | + of_node_put(child); ? return ...; ) ... } // Signed-off-by: Julia Lawall Signed-off-by: Rob Herring

of/overlay: Remove unused variable

2015-03-10T15:34:33+00:00

Commit 3e7f7626fd49a ("of/overlay: Do not generate duplicate nodes") removed the only use of the 'grandchild' variable, which leads to the following build warning: drivers/of/overlay.c: In function 'of_overlay_apply_single_device_node': drivers/of/overlay.c:89:31: warning: unused variable 'grandchild' [-Wunused-variable] struct device_node *tchild, *grandchild; ^ Remove this unused variable.

of/overlay: Directly include idr.h

2015-03-02T14:08:40+00:00

The overlay code uses IDRs but does not explicitly include the header providing the interface, instead relying on an implicit inclusion. Make the dependency explicit to avoid potential future build issues if the implicit inclusion goes away. Signed-off-by: Mark Brown Signed-off-by: Rob Herring

of/overlay: Do not generate duplicate nodes

2015-01-22T15:36:48+00:00

During the course of the rewrites a bug sneaked in when dealing with children nodes of overlays, which ends up duplicating sub nodes. Simply remove the duplicate traversal of child nodes to fix. Signed-off-by: Pantelis Antoniou Signed-off-by: Grant Likely
