2018-12-21of: __of_detach_node() - remove node from phandle cacheFrank Rowand3-1/+37
Non-overlay dynamic devicetree node removal may leave the node in the phandle cache. Subsequent calls to of_find_node_by_phandle() will incorrectly find the stale entry. Remove the node from the cache. Add paranoia checks in of_find_node_by_phandle() as a second level of defense (do not return cached node if detached, do not add node to cache if detached). Fixes: 0b3ce78e90fc ("of: cache phandle nodes to reduce cost of of_find_node_by_phandle()") Reported-by: Michael Bringmann <mwb@linux.vnet.ibm.com> Cc: stable@vger.kernel.org # v4.17+ Signed-off-by: Frank Rowand <frank.rowand@sony.com> Signed-off-by: Rob Herring <robh@kernel.org>
2018-12-21of: of_node_get()/of_node_put() nodes held in phandle cacheFrank Rowand1-24/+46
The phandle cache contains struct device_node pointers. The refcount of the pointers was not incremented while in the cache, allowing use after free error after kfree() of the node. Add the proper increment and decrement of the use count.

2018-12-13dt-bindings: Add a writing DT schemas how-to and annotated exampleRob Herring2-0/+300
Add a how-to doc on writing DT schema documentation. This gives a description of each section and details on how to validate the DT schema file. The DT schema are written using json-schema vocabulary in a YAML encoded document. Using jsonschema gives us access to existing tooling. A YAML encoding gives us something easy to edit. The example is annotated to help explain what each section does. This example is just the tip of the iceberg, but is it the part most developers writing bindings will interact with. Backing all this up are meta-schema (to validate the binding schemas), some DT core schema, YAML encoded DT output with dtc, and a small number of python scripts to run validation.

2018-12-13kbuild: Add support for DT binding schema checksRob Herring7-6/+67
This adds the build infrastructure for checking DT binding schema documents and validating dts files using the binding schema. Check DT binding schema documents: make dt_binding_check Build dts files and check using DT binding schema: make dtbs_check Optionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to use for validation. This makes it easier to find and fix errors generated by a specific schema. Currently, the validation targets are separate from a normal build to avoid a hard dependency on the external DT schema project and because there are lots of warnings generated.

Add DT binding documentation for Sierra PHY. The PHY supports a number of different protocols, including PCIe and USB. The PHY lanes may be configured as single or multi-lane links. Each link is treated as a separate sub-node. For example, if there are 4 lanes in total the first 2 might be configured as a multi-lane PCIe link while the other two are single lane USB links, and in this case there would be 3 sub-nodes. There are two resets for the PHY block (one for APB register access, one for the PHY link) and separate resets for each link. For multi-lane links, the reset corresponds to the reset line on the master lane, the resets on other lanes have no effect.
