+Description
+-----------
+
+This driver implements support for Infineon XDP710 Hot-Swap Controller.
+
+Device compliant with:
+
+- PMBus rev 1.3 interface.
+
+Device supports direct and linear format for reading input voltage,
+output voltage, output current, input power and temperature.
+
+The driver exports the following attributes via the 'sysfs' files
+for input voltage:
+
+**in1_input**
+
+**in1_label**
+
+**in1_max**
+
+**in1_max_alarm**
+
+**in1_min**
+
+**in1_min_alarm**
+
+The driver provides the following attributes for output voltage:
+
+**in2_input**
+
+**in2_label**
+
+**in2_alarm**
+
+The driver provides the following attributes for output current:
+
+**curr1_input**
+
+**curr1_label**
+
+**curr1_alarm**
+
+**curr1_max**
+
+The driver provides the following attributes for input power:
+
+**power1_input**
+
+**power1_label**
+
+**power1_alarm**
+
+The driver provides the following attributes for temperature:
+
+**temp1_input**
+
+**temp1_max**
+
+**temp1_max_alarm**
+
+**temp1_crit**
+
+**temp1_crit_alarm**

That's not the tag you received. Please do not modify the tags. Quotes
are not needed.
Best regards,
Krzysztof
I use b4 download and apply it, I think it is a tool issue, I can fix
in the next version.
Thank you for your feedback.

Just did it now:
b4 trailers -C -u -F '[email protected]>'
Calculating patch-ids from commits, this may take a moment...
Grabbing thread from

Looking for additional code-review trailers on lore.kernel.org
