Merge tag 'soc-drivers-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc 

Pull ARM SoC driver updates from Arnd Bergmann:
 "There are few major updates in the SoC specific drivers, mainly the
  usual reworks and support for variants of the existing SoC. While this
  remains Arm centric for the most part, the branch now also contains
  updates to risc-v and loongarch specific code in drivers/soc/.

  Notable changes include:

   - Support for the newly added Qualcomm Snapdragon variants (MSM8956,
     MSM8976, SM6115, SM4250, SM8150, SA8155 and SM8550) in the soc ID,
     rpmh, rpm, spm and powerdomain drivers.

   - Documentation for the somewhat controversial qcom,board-id
     properties that are required for booting a number of machines

   - A new SoC identification driver for the loongson-2 (loongarch)
     platform

   - memory controller updates for stm32, tegra, and renesas.

   - a new DT binding to better describe LPDDR2/3/4/5 chips in the
     memory controller subsystem

   - Updates for Tegra specific drivers across multiple subsystems,
     improving support for newer SoCs and better identification

   - Minor fixes for Broadcom, Freescale, Apple, Renesas, Sifive, TI,
     Mediatek and Marvell SoC drivers"

An LPDDR channel is a completely independent set of LPDDR pins (DQ, CA, CS,
CK, etc.) that connect one or more LPDDR chips to a host system. The main
purpose of this node is to overall LPDDR topology of the system, including the
amount of individual LPDDR chips and the ranks per chip.

The number of DQ pins in the channel. If this number is different
from (a multiple of) the io-width of the LPDDR chip, that means that
multiple instances of that type of chip are wired in parallel on this
channel (with the channel's DQ pins split up between the different
chips, and the CA, CS, etc. pins of the different chips all shorted
together). This means that the total physical memory controlled by a
channel is equal to the sum of the densities of each rank on the
connected LPDDR chip, times the io-width of the channel divided by
the io-width of the LPDDR chip.

title: Peripheral-specific properties for a Memory Controller bus.
description:
Many Memory Controllers need to add properties to peripheral devices.
They could be common properties like reg or they could be controller
specific like delay in clock or data lines, etc. These properties need
to be defined in the peripheral node because they are per-peripheral
and there can be multiple peripherals attached to a controller. All
those properties are listed here. The controller specific properties
should go in their own separate schema that should be referenced
from here.

help
The global utilities block controls PCIE device enabling, alternate
function selection for multiplexed signals, consistency of HDA, USB
and PCIE, configuration of memory controller, rtc controller, lio
controller, and clock control. This patch adds a driver to manage
and access global utilities block for LoongArch architecture Loongson-2
SoCs. Initially only reading SVR and registering soc device are
supported. Other guts accesses, such as reading firmware configuration
by default, should eventually be added into this driver as well.
