+What:		/sys/bus/i3c/devices/i3c-<bus-id>
+KernelVersion:  5.0
+Contact:	linux-i3c@vger.kernel.org
+Description:
+		An I3C bus. This directory will contain one sub-directory per
+		I3C device present on the bus.
+
+What:		/sys/bus/i3c/devices/i3c-<bus-id>/current_master
+KernelVersion:  5.0
+Contact:	linux-i3c@vger.kernel.org
+Description:
+		Expose the master that owns the bus (<bus-id>-<master-pid>) at
+		the time this file is read. Note that bus ownership can change
+		overtime, so there's no guarantee that when the read() call
+		returns, the value returned is still valid.
+
+What:		/sys/bus/i3c/devices/i3c-<bus-id>/mode
+KernelVersion:  5.0
+Contact:	linux-i3c@vger.kernel.org
+Description:
+		I3C bus mode. Can be "pure", "mixed-fast" or "mixed-slow". See
+		the I3C specification for a detailed description of what each
+		of these modes implies.
+
+What:		/sys/bus/i3c/devices/i3c-<bus-id>/i3c_scl_frequency
+KernelVersion:  5.0
+Contact:	linux-i3c@vger.kernel.org
+Description:
+		The frequency (expressed in Hz) of the SCL signal when
+		operating in I3C SDR mode.
+
+What:		/sys/bus/i3c/devices/i3c-<bus-id>/i2c_scl_frequency
+KernelVersion:  5.0
+Contact:	linux-i3c@vger.kernel.org
+Description:
+		The frequency (expressed in Hz) of the SCL signal when
+		operating in I2C mode.
+
+What:		/sys/bus/i3c/devices/i3c-<bus-id>/dynamic_address
+KernelVersion:  5.0
+Contact:	linux-i3c@vger.kernel.org
+Description:
+		Dynamic address assigned to the master controller. This
+		address may change if the bus is re-initialized.
+
+What:		/sys/bus/i3c/devices/i3c-<bus-id>/bcr
+KernelVersion:  5.0
+Contact:	linux-i3c@vger.kernel.org
+Description:
+		BCR stands for Bus Characteristics Register and express the
+		device capabilities in term of speed, maximum read/write
+		length, etc. See the I3C specification for more details.
+		This entry describes the BCR of the master controller driving
+		the bus.
+
+What:		/sys/bus/i3c/devices/i3c-<bus-id>/dcr
+KernelVersion:  5.0
+Contact:	linux-i3c@vger.kernel.org
+Description:
+		DCR stands for Device Characteristics Register and express the
+		device capabilities in term of exposed features. See the I3C
+		specification for more details.
+		This entry describes the DCR of the master controller driving
+		the bus.
+
+What:		/sys/bus/i3c/devices/i3c-<bus-id>/pid
+KernelVersion:  5.0
+Contact:	linux-i3c@vger.kernel.org
+Description:
+		PID stands for Provisional ID and is used to uniquely identify
+		a device on a bus. This PID contains information about the
+		vendor, the part and an instance ID so that several devices of
+		the same type can be connected on the same bus.
+		See the I3C specification for more details.
+		This entry describes the PID of the master controller driving
+		the bus.
+
+What:		/sys/bus/i3c/devices/i3c-<bus-id>/hdrcap
+KernelVersion:  5.0
+Contact:	linux-i3c@vger.kernel.org
+Description:
+		Expose the HDR (High Data Rate) capabilities of a device.
+		Returns a list of supported HDR mode, each element is separated
+		by space. Modes can be "hdr-ddr", "hdr-tsp" and "hdr-tsl".
+		See the I3C specification for more details about these HDR
+		modes.
+		This entry describes the HDRCAP of the master controller
+		driving the bus.
+
+What:		/sys/bus/i3c/devices/i3c-<bus-id>/<bus-id>-<device-pid>
+KernelVersion:  5.0
+Contact:	linux-i3c@vger.kernel.org
+Description:
+		An I3C device present on I3C bus identified by <bus-id>. Note
+		that all devices are represented including the master driving
+		the bus.
