Merge tag 'soc-drivers-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "The main change this time was the introduction of the drivers/genpd
  subsystem that gets split out from drivers/soc to keep common
  functionality together.

  The SCMI driver subsystem gets an update to version 3.2 of the
  specification. There are also updates to memory, reset and other
  firmware drivers.

  On the soc driver side, the updates are mostly cleanups across a
  number of Arm platforms. On driver for loongarch adds power management
  for DT based systems, another driver is for HiSilicon's Arm server
  chips with their HCCS system health interface.

  The remaining updates for the most part add support for additional
  hardware in existing drivers or contain minor cleanups. Most of these
  are for the Qualcomm Snapdragon platform"

+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.
