2020-11-06dt-bindings: memory: tegra20: emc: Document OPP table and voltage regulatorDmitry Osipenko1-0/+16
The SoC core voltage can't be changed without taking into account the clock rate of External Memory Controller. Document OPP table that will be used for dynamic voltage frequency scaling, taking into account EMC voltage requirement. Document optional core voltage regulator, which is optional because some boards may have a fixed core regulator and still frequency scaling may be desired to have.

2020-11-06dt-bindings: memory: tegra20: emc: Document nvidia, memory-controller propertyDmitry Osipenko1-0/+2
Tegra20 External Memory Controller talks to DRAM chips and it needs to be reprogrammed when memory frequency changes. Tegra Memory Controller sits behind EMC and these controllers are tightly coupled. This patch adds the new phandle property which allows to properly express connection of EMC and MC hardware in a device-tree, it also put the Tegra20 EMC binding on par with Tegra30+ EMC bindings, which is handy to have.

2020-11-06ftrace: Reverse what the RECURSION flag means in the ftrace_opsSteven Rostedt (VMware)1-20/+58
Now that all callbacks are recursion safe, reverse the meaning of the RECURSION flag and rename it from RECURSION_SAFE to simply RECURSION. Now only callbacks that request to have recursion protecting it will have the added trampoline to do so. Also remove the outdated comment about "PER_CPU" when determining to use the ftrace_ops_assist_func.

2020-11-04platform/x86: Intel PMT class driverAlexander Duyck1-0/+54
Intel Platform Monitoring Technology is meant to provide a common way to access telemetry and system metrics. Register mappings are not provided by the driver. Instead, a GUID is read from a header for each endpoint. The GUID identifies the device and is to be used with an XML, provided by the vendor, to discover the available set of metrics and their register mapping. This allows firmware updates to modify the register space without needing to update the driver every time with new mappings. Firmware writes a new GUID in this case to specify the new mapping. Software tools with access to the associated XML file can then interpret the changes. The module manages access to all Intel PMT endpoints on a system, independent of the device exporting them. It creates an intel_pmt class to manage the devices. For each telemetry endpoint, sysfs files provide GUID and size information as well as a pointer to the parent device the telemetry came from. Software may discover the association between endpoints and devices by iterating through the list in sysfs, or by looking for the existence of the class folder under the device of interest. A binary sysfs attribute of the same name allows software to then read or map the telemetry space for direct access.
