LinuxLists.cc - [PATCH v2 00/12] Make I2C terminology more inclusive for I2C Algobit and consumers

Subject: [PATCH v2 00/12] Make I2C terminology more inclusive for I2C Algobit and consumers

2024-05-03 18:15:11

Subject: [PATCH v2 01/12] drm/amdgpu, drm/radeon: Make I2C terminology more inclusive

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

Subject: [PATCH v2 03/12] drm/i915: Make I2C terminology more inclusive

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

It looks like the ack is not needed since we are merging this through
drm-intel-next. But I'm planing to merge this only after seeing the
main drivers/i2c accepting the new terminology. So we don't have a
risk of that getting push back and new names there and we having
to rename it once again.

Jani, what bits were you concerned that were not necessarily i2c?
I believe although not necessarily/directly i2c, I believe they
are related and could benefit from the massive single shot renable.
or do you have any better split to suggest here?

This is not actually I2C related as far as I could tell when I was making the change, so this was more of a typo fix.

If we want to improve this, a quick check with the eDP v1.5a spec suggests using primary/secondary instead,
though in a global fashion rather than specifically for eDP transcoders. There is also source/sink terminology
in the spec related to DP encoders.

Which would be a more acceptable change here?

Thanks,

hmmm probably better to split the patches and align with the spec naming where it applies.
and with i2c name where it applies.

Yeah this one is completely unrelated to i2c and aux, and what the eDP
spec says is irrelevant here. This should follow Intel hw specs.
