2021-02-04coresight: etm4x: Clean up exception level masksSuzuki K Poulose3-46/+60
etm4_get_access_type() calculates the exception level bits for use in address comparator registers. This is also used by the TRCVICTLR register by shifting to the required position. This patch cleans up the logic to make etm4_get_access_type() calculate a generic mask which can be used by all users by shifting to their field. No functional changes intended.

We rely on the ETM architecture version to decide whether Secure EL2 is available on the CPU for excluding the level for address comparators and viewinst main control register.

2021-02-04coresight: etm4x: Hide sysfs attributes for unavailable registersSuzuki K Poulose2-0/+57
Some of the management registers in ETMv4.x are not accessible via system register instructions. Thus we must hide the sysfs files exposing them to the userspace, to prevent system crashes. This patch adds an is_visible() routine to control the visibility at runtime for the registers that may not be accessed.

2021-02-04coresight: etm4x: Add sysreg access helpersSuzuki K Poulose2-22/+353
ETM architecture defines the system instructions for accessing via register accesses. Add basic support for accessing a given register via system instructions. We split the list of registers as : 1) Accessible only from memory mapped interface 2) Accessible from system register instructions. All registers are accessible via the memory-mapped interface. However, some registers are not accessible via the system instructions. This list is then used to further filter out the files we expose via sysfs.

2021-02-04coresight: etm4x: Make offset available for sysfs attributesSuzuki K Poulose1-58/+57
Some of the ETM management registers are not accessible via system instructions. Thus we need to filter accesses to these registers depending on the access mechanism for the ETM at runtime. The driver can cope with this for normal operation, by regular checks. But the driver also exposes them via sysfs, which now needs to be removed. So far, we have used the generic coresight sysfs helper macros to export a given device register, defining a "show" operation per register. This is not helpful to filter the files at runtime, based on the access. In order to do this dynamically, we need to filter the attributes by offsets and hard coded "show" functions doesn't make this easy. Thus, switch to extended attributes, storing the offset in the scratch space. This allows us to implement filtering based on the offset and also saves us some text size. This will be later used for determining a given attribute must be "visible" via sysfs.

2021-02-04coresight: etm4x: Convert all register accessesSuzuki K Poulose3-172/+188
Convert all register accesses from etm4x driver to use a wrapper to allow switching the access at runtime with little overhead. co-developed by sed tool ;-), mostly equivalent to : s/readl\(_relaxed\)\?(drvdata->base + \(.*\))/etm4x_\1_read32(csdev, \2) s/writel\(_relaxed\)\?(\(.*\), drvdata->base + \(.*\))/etm4x_\1_write32(csdev, \2, \3) We don't want to replace them with the csdev_access_* to avoid a function call for every register access for system register access. This is a prepartory step to add system register access later where the support is available.

Consider an amba driver with a .probe but without a .remove callback (e.g. pl061_gpio_driver). The function amba_probe() is called to bind a device and so dev_pm_domain_attach() and others are called. As there is no remove callback amba_remove() isn't called at unbind time however and so calling dev_pm_domain_detach() is missed and the pm domain keeps active. To fix this always use the core driver callbacks and handle missing amba callbacks there. For probe refuse registration as a driver without probe doesn't make sense.
