Commit Message

Easwar Hariharan March 29, 2024, 5 p.m. UTC
I2C v7, SMBus 3.2, and I3C specifications have replaced "master/slave"
with more appropriate terms. Inspired by and following on to Wolfram's
series to fix drivers/i2c/[1], fix the terminology for users of
I2C_ALGOBIT bitbanging interface, now that the approved verbiage exists
in the specification.

Compile tested, no functionality changes intended

I don't understand why we forget that i3c is 1.1.1 :-)

The specification talks about:

 - master -> controller
 - slave -> target (and not client)

But both you and Wolfram have used client. I'd like to reach
some more consistency here.

Thanks,
Andi

Ah, it was in Wolfram's individual commit messages "They are also more specific because we distinguish now between a remote
entity ("client") and a local one ("target")."

Thanks,
Easwar

I don't have a preference between using target and client. As I mentioned in the thread fork, my
information came entirely from Wolfram's cover letter and patch messages. I'll follow along with
whatever you and Wolfram settle on.

Thanks,
