i2c: add kdoc for the new debugfs entry of clients (2025-01-15 22:04:06 +0100)
----------------------------------------------------------------
i2c-for-6.14-rc1
Core:
- list-based mechanisms for handling auto-detected and userspace created
clients are replaced with a flag-based approach. The resulting code is
much simpler as well as the locking.
- i2c clients now get a default debugfs dir managed by the I2C core.
Drivers don't have to maintain their own directory anymore.
Drivers:
- xiic gains atomic_transfer support
- imx-lpi2c gains DMA and target mode support
- riic gets a collection of cleanups
- npcm gets a better timeout handling and more precise frequency setups
- davinci loses the unused platform_data
The rest is regular driver updates and improvements.
AT24:
- add new compatibles for at24 variants from Giantec and Puya
Semiconductor (together with a new vendor prefix)
