This is a follow-up to the previously rejected series[1] which partially
removed the at24_platform_data structure. After further development and
taking reviews into account, this series finally removes that struct
completely but not without touching many different parts of the code
base.
Since I took over maintainership of the at24 driver I've been working
towards removing at24_platform_data in favor for device properties.
DaVinci is the only platform that's still using it - all other users
have already been converted.
One of the obstacles in case of DaVinci is removing the setup() callback
from the pdata struct, the only user of which are some davinci boards.
Most boards use the EEPROM to store the MAC address. This series adds
support for cell lookups to the nvmem framework, registers relevant
cells for all users, adds nvmem support to eth_platform_get_mac_address(),
converts davinci_emac driver to using it and replaces at24_platform_data
with device properties.
There's also one board (da850-evm) which uses MTD for reading the MAC
address. I used the patch from Alban Bedel's previous submission[2] to
add support for nvmem to the MTD framework. Since this user doesn't
need device tree, I dropped Alban's patches modifying the DT bindings.
We can add that later once an agreement is reached. For the time being
MTD devices are registered as nvmem devices and we're registering the
mac-address cell using the cell lookup mechanism.
This series adds a blocking notifier chain to the nvmem framework, so
that we can keep the EEPROM reading code in the mityomapl138 board file
with only slight modifications.
I also included some minor fixes to the modified code.
Tested on da850-evm & dm365-evm.

Bartosz Golaszewski (28):
nvmem: add support for cell lookups
Documentation: nvmem: document lookup entries
nvmem: add a notifier chain
nvmem: provide nvmem_dev_name()
nvmem: remove the name field from struct nvmem_device

nvmem parts looks good to me other then few trivial kernel doc comments!
I can either Ack those patches or Send them after rc3-4 to Greg KH as
4.20 material.
Thanks
