2019-06-20 | coresight: Rename of_coresight to coresight-platform | Suzuki K Poulose | |
Rename the firmware handling file to a more generic name, in preparation for adding ACPI support. Right now we only support DT and we have all the platform handling code in of_coresight.c. Let us rename the file to coresight-platform.c in order to keep the platform handling in a single place for DT and the upcoming ACPI support.

2019-02-08 | coresight: Use of_node_name_eq for node name comparisons | Rob Herring | |
Convert string compares of DT node names to use of_node_name_eq helper instead. This removes direct access to the node name pointer.

2018-09-25 | coresight: Cleanup coresight DT bindings | Suzuki K Poulose | |
The coresight drivers relied on default bindings for graph in DT, while reusing the "reg" field of the "ports" to indicate the actual hardware port number for the connections. This can cause duplicate ports with same addresses, but different direction. However, with the rules getting stricter for the address mismatch with the label, it is no longer possible to use the port address field for the hardware port number. This patch introduces new DT binding rules for coresight components, based on the same generic DT graph bindings, but avoiding the address duplication. - All output ports must be specified under a child node with name "out-ports". - All input ports must be specified under a childe node with name "in-ports". - Port address should match the hardware port number. The support for legacy bindings is retained, with a warning.

2018-09-25 | coresight: platform: Cleanup coresight connection handling | Suzuki K Poulose | |
The platform code parses the component connections and populates a platform-description of the output connections in arrays of fields (which is never freed). This is later copied in the coresight_register to a newly allocated area, represented by coresight_connection(s). This patch cleans up the code dealing with connections by making use of the "coresight_connection" structure right at the platform code and lets the generic driver simply re-use information provided by the platform. Thus making it reader friendly as well as avoiding the wastage of unused memory.

2018-09-25 | coresight: Fix remote endpoint parsing | Suzuki K Poulose | |
When parsing the remote endpoint of an output port, we do : rport = of_graph_get_remote_port(ep); rparent = of_graph_get_remote_port_parent(ep); and then parse the "remote_port" as if it was the remote endpoint, which is wrong. The code worked fine because we used endpoint number as the port number. Let us fix it and optimise a bit as: remote_ep = of_graph_get_remote_endpoint(ep); if (remote_ep) remote_parent = of_graph_get_port_parent(remote_ep); and then, parse the remote_ep for the port/endpoint details.

2018-06-12 | treewide: devm_kzalloc() -> devm_kcalloc() | Kees Cook | |
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

2016-08-31 | coresight: delay initialisation when children are missing | Mathieu Poirier | |
Depending on when CoreSight device are discovered it is possible that some IP block may be referencing devices that have not been added to the bus yet. The end result is missing nodes in the CoreSight topology even when the devices are present and properly initialised. This patch solves the problem by asking the driver core to try initialising the device at a later time when the children of a CoreSight node are missing.

2016-02-20 | drivers/hwtracing: make coresight-* explicitly non-modular | Paul Gortmaker | |
None of the Kconfig currently controlling compilation of any of the files here are tristate, meaning that none of it currently is being built as a module by anyone. We need not be concerned about .remove functions and blocking the unbind sysfs operations, since that was already done in a recent commit. Lets remove any remaining modular references, so that when reading the drivers there is no doubt they are builtin-only. All drivers get mostly the same changes, so they are handled in batch. Changes are (1) convert to builtin_amba_driver, (2) delete module.h include where unused, and (3) relocate the description into the comments so we don't need MODULE_DESCRIPTION and associated tags. The etm3x and etm4x use module_param_named, and have been adjusted to just include moduleparam.h for that purpose. In commit f309d4443130bf814e991f836e919dca22df37ae ("platform_device: better support builtin boilerplate avoidance") we introduced the builtin_driver macro. Here we use that support and extend it to amba driver registration, so where a driver is clearly non-modular and builtin-only, we can update with the simple mapping of module_amba_driver(...) ---> builtin_amba_driver(...) Since module_amba_driver() uses the same init level priority as builtin_amba_driver() the init ordering remains unchanged with this commit.
