2021-04-06Revert "soc: fsl: qe: introduce qe_io{read,write}* wrappers"Christophe Leroy
This reverts commit 6ac9b61786cc64ae5cbfb69413137656f72e8204. This commit was required because at that time, ioread/iowrite functions were sub-optimal on powerpc/32 compared to the architecture specific in_/out_ IO accessors. But there are now equivalent since commit 894fa235eb4c ("powerpc: inline iomap accessors"). Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Li Yang <leoyang.li@nxp.com>
2021-04-06soc: fsl: guts: fix comment syntax in fileAditya Srivastava
The opening comment mark '/**' is used for kernel-doc comments. There are certain comments in include/linux/fsl/guts.h which follows this syntax, but the content inside does not comply with kernel-doc. E.g., opening comment for "Freecale 85xx and 86xx Global Utilties register set" follows kernel-doc syntax(i.e., '/**'), but the content inside does not comply with any kernel-doc specification (function, struct, etc). This causes unwelcomed warning from kernel-doc: "warning: expecting prototype for Freecale 85xx and 86xx Global Utilties register set(). Prototype was for __FSL_GUTS_H__() instead" Replace all such comment occurrences with general comment format, i.e. '/*' to pervent kernel-doc from parsing these.

2021-04-06vfio: Make vfio_device_ops pass a 'struct vfio_device *' instead of 'void *'Jason Gunthorpe
This is the standard kernel pattern, the ops associated with a struct get the struct pointer in for typesafety. The expected design is to use container_of to cleanly go from the subsystem level type to the driver level type without having any type erasure in a void *.

2021-04-06vfio: Split creation of a vfio_device into init and register opsJason Gunthorpe
This makes the struct vfio_device part of the public interface so it can be used with container_of and so forth, as is typical for a Linux subystem. This is the first step to bring some type-safety to the vfio interface by allowing the replacement of 'void *' and 'struct device *' inputs with a simple and clear 'struct vfio_device *' For now the self-allocating vfio_add_group_dev() interface is kept so each user can be updated as a separate patch. The expected usage pattern is driver core probe() function: my_device = kzalloc(sizeof(*mydevice)); vfio_init_group_dev(&my_device->vdev, dev, ops, mydevice); /* other driver specific prep */ vfio_register_group_dev(&my_device->vdev); dev_set_drvdata(dev, my_device); driver core remove() function: my_device = dev_get_drvdata(dev); vfio_unregister_group_dev(&my_device->vdev); /* other driver specific tear down */ kfree(my_device); Allowing the driver to be able to use the drvdata and vfio_device to go to/from its own data. The pattern also makes it clear that vfio_register_group_dev() must be last in the sequence, as once it is called the core code can immediately start calling ops. The init/register gap is provided to allow for the driver to do setup before ops can be called and thus avoid races.

2021-04-06nvme: implement non-mdts command limitsKeith Busch
Commands that access LBA contents without a data transfer between the host historically have not had a spec defined upper limit. The driver set the queue constraints for such commands to the max data transfer size just to be safe, but this artificial constraint frequently limits devices below their capabilities. The NVMe Workgroup ratified TP4040 defines how a controller may advertise their non-MDTS limits. Use these if provided and default to the current constraints if not. Since the Dataset Management command limits are defined in logical blocks, but without a namespace to tell us the logical block size, the code defaults to the safe 512b size.

2021-04-06soundwire: add static port mapping supportSrinivas Kandagatla
Some of the SoundWire device ports are statically mapped to Controller ports during design, however there is no way to expose this information to the controller. Controllers like Qualcomm ones use this info to setup static bandwidth parameters for those ports. A generic port allocation is not possible in this cases! So this patch adds a new member m_port_map to struct sdw_slave to expose this static map.

2021-04-04cgroup: Add misc cgroup controllerVipin Sharma
The Miscellaneous cgroup provides the resource limiting and tracking mechanism for the scalar resources which cannot be abstracted like the other cgroup resources. Controller is enabled by the CONFIG_CGROUP_MISC config option. A resource can be added to the controller via enum misc_res_type{} in the include/linux/misc_cgroup.h file and the corresponding name via misc_res_name[] in the kernel/cgroup/misc.c file. Provider of the resource must set its capacity prior to using the resource by calling misc_cg_set_capacity(). Once a capacity is set then the resource usage can be updated using charge and uncharge APIs. All of the APIs to interact with misc controller are in include/linux/misc_cgroup.h. Miscellaneous controller provides 3 interface files. If two misc resources (res_a and res_b) are registered then: misc.capacity A read-only flat-keyed file shown only in the root cgroup. It shows miscellaneous scalar resources available on the platform along with their quantities:: $ cat misc.capacity res_a 50 res_b 10 misc.current A read-only flat-keyed file shown in the non-root cgroups. It shows the current usage of the resources in the cgroup and its children:: $ cat misc.current res_a 3 res_b 0 misc.max A read-write flat-keyed file shown in the non root cgroups. Allowed maximum usage of the resources in the cgroup and its children.:: $ cat misc.max res_a max res_b 4 Limit can be set by:: # echo res_a 1 > misc.max Limit can be set to max by:: # echo res_a max > misc.max Limits can be set more than the capacity value in the misc.capacity file.

2021-04-02kunit: support failure from dynamic analysis toolsUriel Guajardo
Add a kunit_fail_current_test() function to fail the currently running test, if any, with an error message. This is largely intended for dynamic analysis tools like UBSAN and for fakes. E.g. say I had a fake ops struct for testing and I wanted my `free` function to complain if it was called with an invalid argument, or caught a double-free. Most return void and have no normal means of signalling failure (e.g. super_operations, iommu_ops, etc.). Key points: * Always update current->kunit_test so anyone can use it. * commit 83c4e7a0363b ("KUnit: KASAN Integration") only updated it for CONFIG_KASAN=y * Create a new header <kunit/test-bug.h> so non-test code doesn't have to include all of <kunit/test.h> (e.g. lib/ubsan.c) * Forward the file and line number to make it easier to track down failures * Declare the helper function for nice __printf() warnings about mismatched format strings even when KUnit is not enabled.

2021-04-02regulator: Add regmap helper for ramp-delay settingMatti Vaittinen
Quite a few regulator ICs do support setting ramp-delay by writing a value matching the delay to a ramp-delay register. Provide a simple helper for table-based delay setting.

2021-04-02regulator: helpers: Export helper voltage listingMatti Vaittinen
Some drivers need to translate voltage values to selectors prior regulator registration. Currently a regulator_desc based list_voltages helper is only exported for regulators using the linear_ranges. Export similar helper also for regulators using simple linear mapping.
