[PATCH v3 0/5] Define i2c_designware in a header file

[PATCH v3 0/5] Define i2c_designware in a header file

[Florian Fainelli]

This patch series depends upon the following two patches being applied:

https://lore.kernel.org/all/20240422084109.3201-1-duanqiangwen@net-swift.com/
https://lore.kernel.org/all/20240422084109.3201-2-duanqiangwen@net-swift.com/

There is no reason why each driver should have to repeat the
"i2c_designware" string all over the place, because when that happens we
see the reverts like the above being necessary.

Given the dependency on the two other patches above, it would make sense
to route this via the networking tree, or wait until a v6.9-rc
containing the above two changes gets merged into one of the i2c/mfd
trees.

Changes in v3:

- incorporate Andy's change removing the MODULE_ALIAS
- created a separate inclusion group as requested by Andy
- changed the string format in txgbe_phy.c

Changes in v2:

- avoid changing i2c-designware-pcidrv.c more than necessary
- move constant to include/linux/platform_data/i2c-designware.h
- add comments as to how this constant is used and why

[PATCH v3 1/5] i2c: designware: Replace MODULE_ALIAS() with MODULE_DEVICE_TABLE()

[Florian Fainelli]

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

As Krzysztof Kozlowski pointed out the better is to use
MODULE_DEVICE_TABLE() as it will be consistent with the content
of the real ID table of the platform devices.

While at it, drop unneeded and unused module alias in PCI glue
driver as PCI already has its own ID table and automatic loading
should just work.

[PATCH v3 2/5] i2c: designware: Create shared header hosting driver name

[Florian Fainelli]

We have a number of drivers that reference the string "i2c_designware"
towards two goals:

- ensure their device gets bound to the i2c_designware platform_driver
- create a clock lookup reference that matches the i2c_designware
  instance number for the i2c-designware-platdrv.c driver to be able to
  lookup the input reference clock

Since this string is copied in a bunch of different places and since it
is possible to get this named wrong (see [1] and [2]) with unintended
consequences, create a header file that hosts that define for other
drivers to use and all agree on the correct name to use.

I read your message and the fact that you provided a diff as a 
suggestion as to what would become acceptable if incorporating your 
suggested change, and made that a v3. If this was not acceptable to you 
from the get go, it would have been clearer with an explicit Nack like 
what others have done now.

Yes, so clearly I failed to convince all of you that if someone was able 
to trip over that problem, something should be done about it. No 
problem, these are not driver I maintain, so if someone hits the same 
issue, lore has the patches now.
