* nvmem: make the naming of arguments in nvmem_cell_get() consistentBartosz Golaszewski2018-09-281-13/+14
| | | | | | | | | | | | | The argument representing the cell name in the nvmem_cell_get() family of functions is not consistend between function prototypes and definitions. Name it 'id' in all those routines. This is in line with other frameworks and can represent both the DT cell name from the nvmem-cell-names property as well as the con_id field from cell lookup entries.

* nvmem: add a notifier chainBartosz Golaszewski2018-09-281-0/+36
| | | | | | | | | | | | | Add a blocking notifier chain with four events (add and remove for both devices and cells) so that users can get notified about the addition of nvmem resources they're waiting for. We'll use this instead of the at24 setup callback in the mityomapl138 board file.

* nvmem: add support for cell lookups from machine codeBartosz Golaszewski2018-09-281-26/+103
| | | | | | | | | | | | | | | | | | | | | | | | Add a way for machine code users to associate devices with nvmem cells. This restores the support for non-DT systems but following a different approach. Cells must now be associated with devices using provided routines and data structures before they can be retrieved using nvmem_cell_get(). It's still possible to define cells statically in nvmem_config but cells created this way still need to be associated with consumers using lookup entries. Note that nvmem_find() must be moved higher in the source file as we want to call it from __nvmem_device_get() for devices that don't have a device node. The signature of __nvmem_device_get() is also changed as it's no longer used to retrieve cells.

* nvmem: resolve cells from DT at registration timeBartosz Golaszewski2018-09-281-48/+75
| | | | | | | | | | | | | | | | Currently we're creating a new cell structure everytime a DT user calls nvmem_cell_get(). Change this behavior by resolving the cells during nvmem provider registration and adding all cells to the provider's list. Make of_nvmem_cell_get() just parse the phandle and look the cell up in the relevant provider's list. Don't drop the cell in nvmem_cell_put().

* nvmem: add support for cell infoBartosz Golaszewski2018-09-281-0/+72
| | | | | | | | | | | | | | | Add new structs and routines allowing users to define nvmem cells from machine code. This global list of entries is parsed when a provider is registered and cells are associated with the relevant nvmem_device struct. A possible improvement for the future is to allow users to register cell tables after the nvmem provider has been registered by updating the cell list at each call to nvmem_(add|del)_cell_table().

* nvmem: remove the global cell listBartosz Golaszewski2018-09-281-49/+15
| | | | | | | | | | | | | | | | | | | | | | | Nvmem subsystem keeps a global list of cells that, for non-DT systems, can only be referenced by cell name, which makes it impossible to have more than one nvmem device with cells named the same. This patch makes every nvmem device the owner of the list of its cells. This effectively removes the support for non-DT systems, but it will be reintroduced following a different approach in subsequent patches. This isn't a problem as support for board files in nvmem is currently broken anyway: any user that would try to get an nvmem cell from the global cell list would remove the cell after the calling nvmem_cell_put(). This can cause anything from a subsequent user not being able to get the cell to double free errors if more users hold reference to the same cell at the same time. Fortunately there are no such users which allows us to rework this part.

* nvmem: change the signature of nvmem_unregister()Bartosz Golaszewski2018-09-281-6/+2
| | | | | | | | | | | | We switched the nvmem framework to using kref instead of manually checking the current number of users in nvmem_unregister() so this function can no longer fail. We also converted all remaining users that still checked the return value of nvmem_unregister() to using devm_nvmem_register(). Make the routine return void.

* uio_hv_generic: defer opening vmbus until first useStephen Hemminger2018-09-251-30/+74
| | | | | | | | | | | | | | | | | This fixes two design flaws in hv_uio_generic. Since hv_uio_probe is called from vmbus_probe with lock held it potentially can cause sleep in an atomic section because vmbus_open will wait for response from host. The hv_uio_generic driver could not handle applications exiting and restarting because the vmbus channel was persistent. Change the semantics so that the buffers are allocated on probe, but not attached to host until device is opened.
