2018-03-14nvmem: meson-efuse: Convert to use devm_nvmem_register()Andrey Smirnov1-14/+2
Drop all of the code related to .remove hook and make use of devm_nvmem_register() instead.

2017-11-08nvmem: set nvmem->owner to nvmem->dev->driver->owner if unsetMasahiro Yamada1-1/+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.

2017-10-20nvmem: meson-efuse: indicate that this driver is only for Meson GX SoCsMartin Blumenstingl1-2/+2
The current Amlogic Meson eFuse driver only supports the 64-bit SoCs (GXBB and newer). Older SoCs cannot be supported by the same driver because they do not use the meson secure monitor firmware to access the hardware.

2017-03-23firmware: meson-sm: Check for buffer output sizeCarlo Caione1-1/+1
After the data is read by the secure monitor driver it is being copied in the output buffer checking only the size of the bounce buffer but not the size of the output buffer. Fix this in the secure monitor driver slightly changing the API. Fix also the efuse driver that it is the only driver using this API to not break bisectability.
