nvmem: Introduce devm_nvmem_(un)register()

2018-03-14T18:28:13+00:00

Introduce devm_nvmem_register()/devm_nvmem_unregister() to make .remove() unnecessary in trivial drivers.

nvmem: core: Allow specifying device name verbatim

2018-03-14T18:28:13+00:00

Add code to allow avoid having nvmem core append a numeric suffix to the end of the name by passing config->id of -1.

nvmem: core: switch to device_property_present for reading property "read-only"

2017-12-19T09:39:33+00:00

Switch to more generic device_property_present to consider also non-DT properties. Signed-off-by: Heiner Kallweit Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

nvmem: core: let stride and word_size default to 1

2017-12-19T09:39:33+00:00

If the caller doesn't set stride and/or word_size in struct nvmem_config then nvmem_register accepts this but we may face strange effects later due to both values being 0. Therefore use 1 as default for both values. Signed-off-by: Heiner Kallweit Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

nvmem: core: Deduplicate bus_find_device() by name matching

2017-12-19T09:39:33+00:00

No need to reinvent the wheel, we have bus_find_device_by_name(). Signed-off-by: Lukas Wunner Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

nvmem: set nvmem->owner to nvmem->dev->driver->owner if unset

2017-11-08T12:54:17+00:00

All nvmem drivers are supposed to set the owner field of struct nvmem_config, but this matches nvmem->dev->driver->owner. As far as I see in drivers/nvmem/ directory, all the drivers are the case. So, make nvmem_register() set the nvmem's owner to the associated driver's owner unless nvmem_config sets otherwise. Remove .owner settings in the drivers that are now redundant.

Merge 4.14-rc5 into char-misc-next

2017-10-16T07:22:22+00:00

We need the fixes in here to resolve merge issues and for testing. Signed-off-by: Greg Kroah-Hartman

nvmem: remove unneeded IS_ENABLED(CONFIG_NVMEM) conditional

2017-09-18T14:20:26+00:00

As you see in drivers/nvmem/Makefile, this C file is compiled only when CONFIG_NVMEM is y or m. So, IS_ENABLED(CONFIG_NVMEM) is always evaluated to 1 in this file. Signed-off-by: Masahiro Yamada Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

nvmem: remove inline in drivers/nvmem/core.c

2017-09-18T14:20:26+00:00

These two functions are defined in .c file, but called just once (at least for now). So, the compiler will fold them into their callers even without the "inline" markers. However, this kind of optimization should not be done by hand. It is compiler's judge after all. Signed-off-by: Masahiro Yamada Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

nvmem: add missing of_node_put() in of_nvmem_cell_get()

2017-09-18T14:12:26+00:00

of_get_next_parent() increments the refcount of the returned node. It should be put when done. Signed-off-by: Masahiro Yamada Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman
