2016-05-04coresight: tmc: allocating memory when neededMathieu Poirier3-27/+170
In it's current form the TMC probe() function allocates trace buffer memory at boot time, event if coresight isn't used. This is highly inefficient since trace buffers can occupy a lot of memory that could be used otherwised. This patch allocates trace buffers on the fly, when the coresight subsystem is solicited. Allocated buffers are released when traces are read using the device descriptors under /dev.

2016-05-04coresight: tmc: splitting driver in ETB/ETF and ETR componentsMathieu Poirier5-261/+357
The TMC block can operate in 3 modes (ETB, ETF and ETR) and accessed via two interfaces (sysFS and Perf). That makes 6 mode to cover, which is way too much coupling for a single file. This patch splits the original TMC driver in 2 halves, one for ETB/ETF and another one for ETR mode. A common core is kept for functionality common to all 3 modes.

According to the TRM before programming the TMC in circular buffer mode (and that for any configuration, ETB, ETR, ETF), the TMCReady bit in the status register has to be set.

2016-05-04coresight: tmc: modifying naming conventionMathieu Poirier1-4/+4
According to the TMC architectural state machine, the 'stopped' state is reached when bit 2 (TMCReady) of the TMC Status register turns to '1'. The code is correct but the naming convention isn't. The 'Triggered' bit occupies position '1' of the TMC Status register and has nothing to do with the indication of the TMC entering the stopped state. As such renaming function "tmc_wait_for_triggered()" and changing the #define to reflect what the code is really doing. This patch has no effect other than clarifying the semantic.

>From a core framework point of view an STM device is a source that is treated the same way as any other tracers. Unlike tracers though STM devices are not associated with a CPU. As such it doesn't make sense to associate the path from an STM device to its sink with a per-cpu variable as it is done for tracers.

2016-05-02drivers: amba: properly handle devices with power domainsMarek Szyprowski1-10/+90
To read pid/cid registers, the probed device need to be properly turned on. When it is inside a power domain, the bus code should ensure that the given power domain is enabled before trying to access device's registers. However in some cases power domain (or clocks) might not be yet available. Returning -EPROBE_DEFER is not a solution in such case, because callers don't handle this special error code. Instead such devices are added to the special list and their registration is retried from periodic worker until all resources are available.

According to full-history-linux commit d3794f4fa7c3edc3 ("[PATCH] M68k update (part 25)"), port operations are allowed on m68k if CONFIG_ISA is defined. However, commit 153dcc54df826d2f ("[PATCH] mem driver: fix conditional on isa i/o support") accidentally changed an "||" into an "&&", disabling it completely on m68k.

When APU = 0, active pullup is disabled (resistor mode). Active Pullup should always be selected unless there is only a single slave on the 1-Wire line."
