Commit 70762abb9f89 ("i2c: Use stable dev_name for ACPI enumerated I2C
slaves") broke the lm-sensors which relies on I2C hwmon slave devices under
/sys/bus/i2c/devices/ to be named as "x-00yz". However if those hwmon
devices are ACPI 5 enumerated their name became "i2c-INTABCD:ij" and sysfs

I'd assume that regmap conversion will happen later quite likely anyhow.
Most of those devices will have I2C/SPI dual interfaces; or people will

In our former i2c driver, i2c clk is enabled and disabled in
xfer function, which contributes to power saving. However,
the clk enable process brings a busy wait delay until the core
is stable. As a result, the performance is sacrificed.
To weigh the power consumption and i2c bus performance, runt

Hello,
This is a resend of the patches that were not picked from the series
"[PATCH 00/27] Export I2C and OF module aliases in missing drivers" [0]
posted about a month ago.
The patches have no dependencies and can be picked individually by the
relevant maintainer.
I preferred to resend instead
The I2C core always reports the MODALIAS uevent as "i2c:"
regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: I2C id table or OF match table).
So drivers needs to export the I2C id table
