[PATCH v2 07/12] of: overlay: expand check of whether overlay changeset can be removed

From: Frank Rowand The test of whether it is safe to remove an overlay changeset looked at whether any node in the overlay changeset was in a subtree rooted at any more recently applied overlay changeset node. The test failed to determine whether any node in the overlay

[PATCH v2 06/12] of: overlay: detect cases where device tree may become corrupt

From: Frank Rowand When an attempt to apply an overlay changeset fails, an effort is made to revert any partial application of the changeset. When an attempt to remove an overlay changeset fails, an effort is made to re-apply any partial reversion of the changeset. The

[PATCH v2 09/12] of: overlay: avoid race condition between applying multiple overlays

From: Frank Rowand The process of applying an overlay consists of: - unflatten an overlay FDT (flattened device tree) into an EDT (expanded device tree) - fixup the phandle values in the overlay EDT to fit in a range above the phandle values in the live device

[PATCH v2 10/12] of: overlay: simplify applying symbols from an overlay

From: Frank Rowand The code to apply symbols from an overlay to the live device tree was implemented with the intent to be minimally intrusive on the existing code. After recent restructuring of the overlay apply code, it is easier to disintangle the code that applies the

[PATCH v2 03/12] of: overlay: rename identifiers to more reflect what they do

[PATCH v2 11/12] of: overlay: remove a dependency on device node full_name

From: Frank Rowand The "%pOF" printf format was recently added to print the full name of a device tree node, with the intent of changing the node full_name field to contain only the node name instead of the full path of the node. dup_and_fixup_symbol_prop() duplicates a

[PATCH v2 05/12] of: overlay: minor restructuring

From: Frank Rowand Continue improving the readability of overlay.c. The previous patches renamed identifiers. This patch is split out from the previous patches to make the previous patches easier to review. Changes are: - minor code restructuring - some

[PATCH v2 12/12] of: overlay: remove unneeded check for NULL kbasename()

[PATCH] of: overlay: move resolve phandles into of_overlay_apply()

From: Frank Rowand Move more code into of_overlay_apply() so that it does not have to be duplicated by each caller of of_overlay_apply(). The test in of_resolve_phandles() that the overlay tree is detached is temporarily disabled so that old style overlay unittests do not
