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. First we add support for nvmem to MTD in a way previously discussed with Boris Brezillon and Srinivas Kandagatla. Then, since most boards use the EEPROM to store the MAC address, we register relevant cells for all users, implement a function that allows to read the MAC address from nvmem (and also replaces the previous DT-specific variant) and make davinci_emac aware of it. Next we switch all davinci users to using at24 device properties instead of platform data. While we're at it: we remove all other traces of the setup callback and platform data from davinci. Finally we remove the at24 platform data structure. I kept the review tags in patches that haven't changed from the last submission. As far as merging of this series goes: I'd like to avoid dragging it over four releases. The series is logically split into five groups: patches 1-2: nvmem and mtd changes patches 3-9: davinci arch-specific changes patches 10-13: networking changes patches 14-24: davinci specific again patch 25: final at24 change With that I believe we can do the following: Greg KH could pick up the first two patches into his char-misc tree. Sekhar would take the second group and the third would go through the networking tree since the first three sets are not linked in any way. This would be merged for 4.21. Then for the next release Sekhar would pick up 14-24, provide an immutable branch for me and I'd merge the final patch for at24 and send it upstream through Wolfram's i2c tree (maybe we could even delay the i2c PR in the merge window to avoid the immutable branch altogether).
