2020-09-18interconnect: qcom: Use icc_sync_stateGeorgi Djakov
Lowering the bandwidth on the bus might have negative consequences if it's done before all consumers had a chance to cast their vote. Now by default the framework sets the bandwidth to maximum during boot. We need to use the icc_sync_state callback to notify the framework when all consumers are probed and there is no need to keep the bandwidth set to maximum anymore.

2020-09-18interconnect: Add sync state supportGeorgi Djakov
The bootloaders often do some initial configuration of the interconnects in the system and we want to keep this configuration until all consumers have probed and expressed their bandwidth needs. This is because we don't want to change the configuration by starting to disable unused paths until every user had a chance to request the amount of bandwidth it needs. To accomplish this we will implement an interconnect specific sync_state callback which will synchronize (aggregate and set) the current bandwidth settings when all consumers have been probed.

2020-09-17uio: free uio id after uio file node is freedLang Dai
uio_register_device() do two things. 1) get an uio id from a global pool, e.g. the id is <A> 2) create file nodes like /sys/class/uio/uio<A> uio_unregister_device() do two things. 1) free the uio id <A> and return it to the global pool 2) free the file node /sys/class/uio/uio<A> There is a situation is that one worker is calling uio_unregister_device(), and another worker is calling uio_register_device(). If the two workers are X and Y, they go as below sequence, 1) X free the uio id <AAA> 2) Y get an uio id <AAA> 3) Y create file node /sys/class/uio/uio<AAA> 4) X free the file note /sys/class/uio/uio<AAA> Then it will failed at the 3rd step and cause the phenomenon we saw as it is creating a duplicated file node.

2020-09-17nvmem: switch to simpler IDA interfaceBartosz Golaszewski
We don't need to specify any ranges when allocating IDs so we can switch to ida_alloc() and ida_free() instead of the ida_simple_ counterparts. ida_simple_get(ida, 0, 0, gfp) is equivalent to ida_alloc_range(ida, 0, UINT_MAX, gfp) which is equivalent to ida_alloc(ida, gfp).

2020-09-17coresight: Make sysfs functional on topologies with per core sinkLinu Cherian
Coresight driver assumes sink is common across all the ETMs, and tries to build a path between ETM and the first enabled sink found using bus based search. This breaks sysFS usage on implementations that has multiple per core sinks in enabled state. To fix this, coresight_get_enabled_sink API is updated to do a connection based search starting from the given source, instead of bus based search. With sink selection using sysfs depecrated for perf interface, provision for reset is removed as well in this API.

2020-09-17coresight: etm4x: Ensure default perf settings filter user/kernelMike Leach
Moving from using an address filter to trace the default "all addresses" range to no filtering to acheive the same result, has caused the perf filtering of kernel/user address spaces from not working unless an explicit address filter was used. This is due to the original code using a side-effect of the address filtering rather than setting the global TRCVICTLR exception level filtering. The use of the mode sysfs file is also similarly affected. A helper function is added to fix both instances.

Below BUG is triggered by call pm_runtime_get_sync() in cti_cpuhp_enable_hw(). It's in CPU hotplug callback with interrupt disabled. Pm_runtime_get_sync() calls clock driver to enable clock which could sleep.

2020-09-17coresight: etm4x: Fix etm4_count race by moving cpuhp callbacks to initSai Prakash Ranjan
etm4_count keeps track of number of ETMv4 registered and on some systems, a race is observed on etm4_count variable which can lead to multiple calls to cpuhp_setup_state_nocalls_cpuslocked(). This function internally calls cpuhp_store_callbacks() which prevents multiple registrations of callbacks for a given state and due to this race, it returns -EBUSY leading to ETM probe failures like below. coresight-etm4x: probe of 7040000.etm failed with error -16 This race can easily be triggered with async probe by setting probe type as PROBE_PREFER_ASYNCHRONOUS and with ETM power management property "arm,coresight-loses-context-with-cpu". Prevent this race by moving cpuhp callbacks to etm driver init since the cpuhp callbacks doesn't have to depend on the etm4_count and can be once setup during driver init. Similarly we move cpu_pm notifier registration to driver init and completely remove etm4_count usage. Also now we can use non cpuslocked version of cpuhp callbacks with this movement.
