* nvmem: bcm-ocotp: Convert to use devm_nvmem_register()Andrey Smirnov2018-03-141-11/+1
| | | | | | | | | | | | | | | | | | | | | Drop all of the code related to .remove hook and make use of devm_nvmem_register() instead.

* nvmem: set nvmem->owner to nvmem->dev->driver->owner if unsetMasahiro Yamada2017-11-081-1/+0
| | | | | | | | | | | | | | | 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.

* nvmem: correct Broadcom OTP controller driver writesOza Pawandeep2017-06-091-2/+2
| | | | | | | | | | | | - use data write offset to write otp data instead of read offset - use OTP program command 0x8 to write otp with ECC rather than just command 0xA without ECC Fixes: 9d59c6e8ae27 ("nvmem: Add the Broadcom OTP controller driver") Signed-off-by: Oza Pawandeep <oza.oza@broadcom.com> Signed-off-by: Scott Branden <scott.branden@broadcom.com> Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* nvmem: Add the Broadcom OTP controller driverJonathan Richardson2016-11-101-0/+335
Add support for 32 and 64-bit versions of Broadcom's On-Chip OTP controller. These controllers are used on SoC's such as Cygnus and Stingray.
