See MAINTAINERS. Might also split the i915 changes to smaller pieces, it's kind of random. And the changes here are not strictly related to I2C AFAICT, so the commit message should be updated.

Can you say more about the changes being "not strictly related to I2C"? My heuristic was to grep for master/slave, and look in the surrounding context for i2c-related terminology (i2c_pin, 7-bit address, struct i2c_adapter, i2c_bus, etc) to confirm that they are i2c-related, then following the references around to make the compiler happy. For e.g., I did not change the many references to bigjoiner master and slave because I understood from context they were not i2c references. A couple examples would help me restrict the changes to I2C, since as mentioned in the discussion on Wolfram's thread, there are places where migrating away from master/slave terms in the code would conflict with the original technical manuals and reduce correlation and understanding of the code. Thanks, Easwar

I guess I was looking at the VBT changes in intel_bios.c. Granted, they do end up being used as i2c addresses. No big deal. I think I'd expect the treewide i2c adapter changes to land first, via i2c, and subsequent cleanups to happen next, via individual driver trees. There's quite a bit of conflict potential merging this outside of drm-intel-next, and there's really no need for that. BR, Jani. > > Thanks, > Easwar >

If we can merge the i915 changes via drm-intel-next, it's probably fine as a big i915 patch. Just the gma500 separated.

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 [1]: https://lore.kernel.org/all/20240322132619.6389-1-wsa+renesas@sang-engineering.com/ Signed-off-by: Easwar Hariharan <eahariha@linux.microsoft.com> --- drivers/gpu/drm/gma500/cdv_intel_lvds.c | 2 +- drivers/gpu/drm/gma500/intel_bios.c | 22 +++++++------- drivers/gpu/drm/gma500/intel_bios.h | 4 +-- drivers/gpu/drm/gma500/intel_gmbus.c | 2 +- drivers/gpu/drm/gma500/psb_drv.h | 2 +- drivers/gpu/drm/gma500/psb_intel_drv.h | 2 +- drivers/gpu/drm/gma500/psb_intel_lvds.c | 4 +-- drivers/gpu/drm/gma500/psb_intel_sdvo.c | 26 ++++++++-------- drivers/gpu/drm/i915/display/dvo_ch7017.c | 14 ++++----- drivers/gpu/drm/i915/display/dvo_ch7xxx.c | 18 +++++------ drivers/gpu/drm/i915/display/dvo_ivch.c | 16 +++++----- drivers/gpu/drm/i915/display/dvo_ns2501.c | 18 +++++------ drivers/gpu/drm/i915/display/dvo_sil164.c | 18 +++++------ drivers/gpu/drm/i915/display/dvo_tfp410.c | 18 +++++------ drivers/gpu/drm/i915/display/intel_bios.c | 22 +++++++------- drivers/gpu/drm/i915/display/intel_ddi.c | 2 +- .../gpu/drm/i915/display/intel_display_core.h | 2 +- drivers/gpu/drm/i915/display/intel_dsi.h | 2 +- drivers/gpu/drm/i915/display/intel_dsi_vbt.c | 18 +++++------ drivers/gpu/drm/i915/display/intel_dvo.c | 14 ++++----- drivers/gpu/drm/i915/display/intel_dvo_dev.h | 2 +- drivers/gpu/drm/i915/display/intel_gmbus.c | 4 +-- drivers/gpu/drm/i915/display/intel_sdvo.c | 30 +++++++++---------- drivers/gpu/drm/i915/display/intel_vbt_defs.h | 4 +-- drivers/gpu/drm/i915/gvt/edid.c | 28 ++++++++--------- drivers/gpu/drm/i915/gvt/edid.h | 4 +-- drivers/gpu/drm/i915/gvt/opregion.c | 2 +- 27 files changed, 150 insertions(+), 150 deletions(-)
