Pull sound updates from Takashi Iwai:
 "Lots of changes in this cycle, but mostly for cleanups and
  refactoring.

   - MIDI2 time-base extension in ALSA sequencer API

  ASoC:
   - Syncing of features between simple-audio-card and the two
     audio-graph cards
   - Support for specifying the order of operations for components
     within cards to allow quirking for unusual systems

<title>net: Add struct kernel_ethtool_ts_info</title>

<id>2111375b85ad173d58e7b8604246a3de60950ac8</id>
<content type='text'>
In prevision to add new UAPI for hwtstamp we will be limited to the struct
ethtool_ts_info that is currently passed in fixed binary format through the
ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code
already started operating on an extensible kernel variant of that
structure, similar in concept to struct kernel_hwtstamp_config vs struct
hwtstamp_config.

Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here
we introduce the kernel-only structure in include/linux/ethtool.h.
The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

qmc_chan_get_byphandle() and the resource managed version retrieve a
channel from a simple phandle.

Extend the API and introduce qmc_chan_get_byphandles_index() and the
resource managed version in order to retrieve a channel from a phandle
list using the provided index to identify the phandle in the list.

Also update qmc_chan_get_byphandle() and the resource managed version to
use qmc_chan_get_byphandles_index() and so avoid code duplication.

Pull clk updates from Stephen Boyd:
 "I'm actually surprised this time. There aren't any new Qualcomm SoC
  clk drivers. And there's zero diff in the core clk framework.

  Instead we have new clk drivers for STM and Sophgo, with
  Samsung^WGoogle in third for the diffstat because they introduced HSI0
  and HSI2 clk drivers for Google's GS101 SoC (high speed interface
  things like PCIe, UFS, and MMC).

  Beyond those big diffs there's the usual updates to various clk
  drivers for incorrect parent descriptions or mising
  MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super
  interesting here.

  New Drivers:
   - STM32MP257 SoC clk driver
   - Airoha EN7581 SoC clk driver
   - Sophgo CV1800B, CV1812H and SG2000 SoC clk driver
   - Loongson-2k0500 and Loongson-2k2000 SoC clk driver
   - Add HSI0 and HSI2 clock controllers for Google GS101
   - Add i.MX95 BLK CTL clock driver

  Updates:
   - Allocate clk_ops dynamically for SCMI clk driver
   - Add support in qcom RCG and RCG2 for multiple configurations for
     the same frequency
   - Use above support for IPQ8074 NSS port 5 and 6 clocks to resolve
     issues
   - Fix the Qualcomm APSS IPQ5018 PLL to fix boot failures of some
     boards
   - Cleanups and fixes for Qualcomm Stromer PLLs
   - Reduce max CPU frequency on Qualcomm APSS IPQ5018
   - Fix Kconfig dependencies of Qualcomm SM8650 GPU and SC8280XP camera
     clk drivers
   - Make Qualcomm MSM8998 Venus clocks functional
   - Cleanup downstream remnants related to DisplayPort across Qualcomm
     SM8450, SM6350, SM8550, and SM8650
   - Reuse the Huayra APSS register map on Qualcomm MSM8996 CBF PLL
   - Use a specific Qualcomm QCS404 compatible for the otherwise generic
     HFPLL
   - Remove Qualcomm SM8150 CPUSS AHB clk as it is unused
   - Remove an unused field in the Qualcomm RPM clk driver
   - Add missing MODULE_DEVICE_TABLE to Qualcomm MSM8917 and MSM8953
     global clock controller drivers
   - Allow choice of manual or firmware-driven control over PLLs, needed
     to fully implement CPU clock controllers on Exynos850
   - Correct PLL clock IDs on ExynosAutov9
   - Propagate certain clock rates to allow setting proper SPI clock
     rates on Google GS101
   - Mark certain Google GS101 clocks critical
   - Convert old S3C64xx clock controller bindings to DT schema
   - Add new PLL rate and missing mux on Rockchip rk3568
   - Add missing reset line on Rockchip rk3588
   - Removal of an unused field in struct rockchip_mmc_clock
   - Amlogic s4/a1: add regmap maximum register for proper debugfs dump
   - Amlogic s4: add MODULE_DEVICE_TABLE() on pll and periph controllers
   - Amlogic pll driver: print clock name on lock error to help debug
   - Amlogic vclk: finish dsi clock path support
   - Amlogic license: fix occurence "GPL v2" as reported by checkpatch
   - Add PM runtime support to i.MX8MP Audiomix
   - Add DT schema for i.MX95 Display Master Block Control
   - Convert to platform remove callback returning void for i.MX8MP
     Audiomix
   - Add SPI (MSIOF) and external interrupt (INTC-EX) clocks on Renesas
     R-Car V4M
   - Add interrupt controller (PLIC) clock and reset on Renesas RZ/Five
   - Prepare power domain support for Renesas RZ/G2L family members, and
     add actual support on Renesas RZ/G3S SoC
   - Add thermal, serial (SCIF), and timer (CMT/TMU) clocks on Renesas
     R-Car V4M
   - Add additional constraints to Allwinner A64 PLL MIPI clock
   - Fix autoloading sunxi-ng clocks when build as a module"

DCP (Data Co-Processor) is able to derive private keys for a fused
random seed, which can be referenced by handle but not accessed by
the CPU. Similarly, DCP is able to store arbitrary keys in four
dedicated key slots located in its secure memory area (internal SRAM).
These keys can be used to perform AES encryption.

Expose these derived keys and key slots through the crypto API via their
handle. The main purpose is to add DCP-backed trusted keys. Other
use cases are possible too (see similar existing paes implementations),
but these should carefully be evaluated as e.g. enabling AF_ALG will
give userspace full access to use keys. In scenarios with untrustworthy
userspace, this will enable en-/decryption oracles.

While moving all the reset code in the PolarFire SoC clock driver to the
reset subsystem, I removed an `#if IS_ENABLED(RESET_CONTROLLER)` from
the driver and moved it to the header, however this was not the correct
thing to do. In the driver such a condition over-eagerly provided a
complete implementation for mpfs_reset_{read,write}() when the reset
subsystem was enabled without the PolarFire SoC reset driver, but in the
header it meant that when the subsystem was enabled and the driver was
not, no implementation for mpfs_reset_controller_register() was
provided. Fix the condition so that the stub implementation of
mpfs_reset_controller_register() is used when the reset driver is
disabled.

Stephen and Philipp, while reviewing patches, said that all of the aux
device creation and the register read/write code could be moved to the
reset subsystem, leaving the clock driver with no implementations of
reset_* functions at all. Move them.

<title>soc: qcom: rpmh-rsc: Enhance check for VRM in-flight request</title>

Each RPMh VRM accelerator resource has 3 or 4 contiguous 4-byte aligned
addresses associated with it. These control voltage, enable state, mode,
and in legacy targets, voltage headroom. The current in-flight request
checking logic looks for exact address matches. Requests for different
addresses of the same RPMh resource as thus not detected as in-flight.

Add new cmd-db API cmd_db_match_resource_addr() to enhance the in-flight
request check for VRM requests by ignoring the address offset.

This ensures that only one request is allowed to be in-flight for a given
VRM resource. This is needed to avoid scenarios where request commands are
carried out by RPMh hardware out-of-order leading to LDO regulator
over-current protection triggering.
