+Description:
+ The /sys/devices/platform/HISI04Bx/chipX/dieX/hccsN/ directory
+ contains read-only attributes exposing information about
+ a HCCS port. The N value in 'hccsN' indicates this port id.
+ The X in 'chipX' indicates the ID of the chip to which the
+ HCCS port belongs. For example, X ranges from to 'n - 1' if the
+ chip number on platform is n.
+ The Y in 'dieY' indicates the hardware id of the die to which
+ the hccs port belongs.
+ Note: type, lane_mode and enable are fixed attributes on running
+ platform.
+
+ The HCCS port have the following attributes:
+
+ ============= ==== =============================================
+ type: (RO) port type (string), e.g. HCCS-v1 -> H32
+ lane_mode: (RO) the lane mode of this port (string), e.g. x8
+ enable: (RO) indicate if this port is enabled (bool).
+ cur_lane_num: (RO) current lane number of this port.
+ link_fsm: (RO) link finite state machine of this port.
+ lane_mask: (RO) current lane mask of this port, every bit
+ indicates a lane.
+ crc_err_cnt: (RO) CRC err count on this port.

+ The firmware running on the processor inside the RPM subsystem allows each
+ component in the system to vote for state of the system resources, such as
+ clocks, regulators and bus frequencies. It implements multiple separate
+ communication interfaces that are described in subnodes, e.g. SMD and MPM:
+

+
+ The services provided by the firmware are only available after the firmware
+ has been loaded and the processor has been released from reset. Usually this
+ happens early in the boot process before the operating system is started.
