Start changing the wording of the I2C main header wrt. the newest I2C v7, SMBus 3.2, I3C specifications and replace "master/slave" with more appropriate terms. This first step renames the members of struct i2c_algorithm. Once all in-tree users are converted, the anonymous union will go away again. All this work will also pave the way for finally seperating the monolithic header into more fine-grained headers like "i2c/clients.h" etc. So, this is not a simple renaming-excercise but also a chance to update the I2C core to recent Linux standards. My motivation is to improve the I2C core API, in general. My motivation is not to clean each and every driver. I think this is impossible because register names based on official documentation will need to stay as they are. But the Linux-internal names should be updated IMO. That being said, I worked on 62 drivers in this series beyond plain renames inside 'struct i2c_algorithm' because the fruits were so low-hanging. Before this series, 112 files in the 'busses/' directory contained 'master' and/or 'slave'. After the series, only 57. Why not? Next step is updating the drivers outside the 'i2c'-folder regarding 'struct i2c_algorithm' so we can remove the anonymous union ASAP. To be able to work on this with minimal dependencies, I'd like to apply this series between -rc1 and -rc2. I hope this will work for you guys. The changes are really minimal. If you are not comfortable with changes to your driver or need more time to review, please NACK the patch and I will drop the patch and/or address the issues separeately. @Andi: are you okay with this approach? It means you'd need to merge -rc2 into your for-next branch. Or rebase if all fails. Speaking of Andi, thanks a lot to him taking care of the controller drivers these days. His work really gives me the freedom to work on I2C core issues again. Also, Renesas deserves a honorable mention here for increased support of my I2C activities. Thank you! If you have comments, hints, etc, please let me know.
