Subject: [PATCH 0/4] i2c: Remove I2C_CLASS_SPD
Date: Mon, 15 Apr 2024 22:47:04 +0200 [thread overview]
Message-ID: <90a0786f-136b-4097-9def-8d52e9e5d3cc@gmail.com> (raw)
Only remaining client driver supporting I2C_CLASS_SPD is jc42. This
type of thermal sensor can be found on several DDR3/DDR4 modules.
i2c_register_spd() instantiates also such thermal sensor i2c devices.
Since 71b494e043d2 ("i2c: i801: Call i2c_register_spd for muxed child
segments") i2c_register_spd() is called also for the remaining use case,
systems with muxed SMBUS segments for SPD EEPROMs. i801 was the last
bus driver supporting I2C_CLASS_SPD.
Therefore I2C_CLASS_SPD class-based instantiation isn't needed any longer,
and we can remove it completely.
I propose to handle this series via the I2C tree.
