I2C v7, SMBus 3.2, and I3C 1.1.1 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

I2C v7, SMBus 3.2, and I3C 1.1.1 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

I2C v7, SMBus 3.2, and I3C 1.1.1 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

I2C v7, SMBus 3.2, and I3C 1.1.1 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

series to fix drivers/i2c/[1], fix the terminology for users of
I2C_ALGOBIT bitbanging interface, now that the approved verbiage exists

I2S specification has also updated the terms in v.3 to use "controller"
and "target" respectively. Make those changes in the relevant spaces as
well.

FWIW we're assuming someone (Wolfram?) will take all of these,
instead of area maintainers picking them individually.
Please let us know if that's incorrect.

I think, based on the trend in the v2 conversation[1], that's correct. If maintainers of
other areas disagree, please chime in.

I2C v7, SMBus 3.2, and I3C 1.1.1 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

Thanks for the ack! I had been addressing feedback as I got it on the v0 series, and it seems
I missed out on updating viafb and smscufx to spec-compliant controller/target terminology like
the v0->v1 changelog calls out before posting v1.
For smscufx, I feel phrasing the following line (as an example)
> -/* sets up I2C Controller for 100 Kbps, std. speed, 7-bit addr, host,
> +/* sets up I2C Controller for 100 Kbps, std. speed, 7-bit addr, *controller*,
would actually impact readability negatively, so I propose to leave smscufx as is.
For viafb, I propose making it compliant with the spec using the controller/target terminology and
posting a v2 respin (which I can send out as soon as you say) and ask you to review again.
What do you think?
Thanks,
Easwar

Why? I don't see much of a difference.

I think we should adopt the spec's language everywhere. That makes it
possible to grep the spec for terms used in the source code. Using
'host' in smscufx appears to introduce yet another term. If you are
worried about using 'I2C controller' and 'controller' in the same
sentence, you can replace 'I2C controller' with 'DDC channel'. That's
even more precise about the purpose of this code.
Best regards
Thomas

Great, thanks! That was exactly my concern, I will fix up smscufx and send a v2.
