From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx> This series contains nvmem framework changes prerequisite for further development of my previous series[1] that aims at removal of the platform data struct from at24 EEPROM driver. First we remove unused APIs and the global cell list. We then switch to using kref instead of manual user counting. Next we simplify the provider unregistration by removing the return value from nvmem_unregister(). Next three patches improve the framework by adding a notifier chain for future use and fixing the issue with nvmem device names. Finally we add support for cell definitions, cell lookups and make DT systems resolve the nvmem cells during provider's registration. Last patches just use the SPDX license identifiers and make the naming convention for some arguments more consistent. Tested both DT and non-DT use cases. [1] https://lkml.org/lkml/2018/8/10/149 v1 -> v2: - extended the lookup structure with a proper con_id independent from the cell name defined in the cell definition table - added a patch that makes the naming convention for the cell name argument in the nvmem_cell_get() family of functions consistent - there were two users of nvmem_unregister() that still checked the return value, now switched to devm_nvmem_register() - fixed build failures reported by kbuild test robot Bartosz Golaszewski (16): nvmem: remove unused APIs nvmem: remove the global cell list nvmem: use kref nvmem: lpc18xx_eeprom: use devm_nvmem_register() nvmem: sunxi_sid: use devm_nvmem_register() nvmem: mxs-ocotp: use devm_nvmem_register() nvmem: change the signature of nvmem_unregister() nvmem: provide nvmem_dev_name() nvmem: remove the name field from struct nvmem_device nvmem: add a notifier chain nvmem: add support for cell info nvmem: resolve cells from DT at registration time nvmem: add support for cell lookups from machine code Documentation: nvmem: document cell tables and lookup entries nvmem: use SPDX license identifiers nvmem: make the naming of arguments in nvmem_cell_get() consistent Documentation/nvmem/nvmem.txt | 31 ++ MAINTAINERS | 1 + drivers/nvmem/core.c | 676 ++++++++++++++++++--------------- drivers/nvmem/lpc18xx_eeprom.c | 6 +- drivers/nvmem/mxs-ocotp.c | 4 +- drivers/nvmem/sunxi_sid.c | 20 +- include/linux/nvmem-consumer.h | 62 ++- include/linux/nvmem-machine.h | 57 +++ include/linux/nvmem-provider.h | 27 +- 9 files changed, 493 insertions(+), 391 deletions(-) create mode 100644 include/linux/nvmem-machine.h -- 2.18.0
