Currently the sdw machine driver uses different way to get the
component name from the DAI name for different codecs in the rtd_init
callback. It means that we need to rely on the rtd_init callback to get
the component name. Add an optional component string to the
asoc_sdw_dai_info struct allows the machine driver to get the component
name directly.
The commit adds the component names for the AMP dais for the preparation
to set card->components string for combined speaker configs.

The usage of MUTEX_MOD1 and MUTEX_MOD2 for calculating mod settings
over 32 has been confusing. To improve consistency and clarity, these
defines need to fit into the same MUTEX_MOD define as possible.
However, MUTEX_MOD1 cannot be directly used for all SoCs because,
for example, the mod1 register (0x34) of MT2712 is not adjacent to
its mod0 register (0x2c). To address this, a `mutex_mod1_reg` field
is introduced in the mutex driver data structure. This allows all
SoCs to use a unified MUTEX_MOD to determine their register offsets.
With this change, the separate usage of MUTEX_MOD1 and MUTEX_MOD2 is
eliminated, simplifying the logic for obtaining offsets and mod IDs.

Files in the arch/s390/boot directory reuse logic from the rest of the
kernel by including certain C and assembly files from the kernel and lib
directories. Some of these included files contain EXPORT_SYMBOL directives.
For instance, arch/s390/boot/cmdline.c includes lib/cmdline.c, which
exports the get_option() function.
This inclusion triggers genksyms processing for the files in
arch/s390/boot, which is unnecessary and slows down the build.
Additionally, when KBUILD_SYMTYPES=1 is set, the generated symtypes data
contain exported symbols that are duplicated with the main kernel. This
duplication can confuse external kABI tools that process the symtypes data.
Address this issue by compiling the files in arch/s390/boot with
-D__DISABLE_EXPORTS.

In order to support the complex power sequencing required by the TH1520
GPU, the AON power domain driver must be responsible for initiating the
corresponding sequencer driver. This functionality is specific to
platforms where the GPU power sequencing hardware is controlled by the
AON block.
Extend the AON power domain driver to check for the presence of the
"gpu-clkgen" reset in its own device tree node.
If the property is found, create and register a new auxiliary device.
This device acts as a proxy that allows the dedicated `pwrseq-thead-gpu`
auxiliary driver to bind and take control of the sequencing logic.

Extend the TH1520 AON to describe the GPU clkgen reset line, required
for proper GPU clock and reset sequencing.
The T-HEAD TH1520 GPU requires coordinated management of two clocks
(core and sys) and two resets (GPU core reset and GPU clkgen reset).
Only the clkgen reset is exposed at the AON level, to support SoC
specific initialization handled through a dedicated auxiliary power
sequencing driver. The GPU core reset remains described in the GPU
device node, as from the GPU driver's perspective, there is only a
single reset line [1].
This follows upstream maintainers' recommendations [2] to abstract SoC
specific details into the PM domain layer rather than exposing them to
drivers directly.

There is a requirement to exit EMLSR if there wasn't enough throughput
in the secondary link.
This is checked in check_tpt_wk, which runs every 5 seconds in a high
throughput scenario (when the throughput blocker isn't set)
It can happen that this worker is running immediately after we entered
EMLSR, and in that case the secondary link didn't have a chance to have
throughput. In that case we will exit EMLSR for no good reason.
Fix this by tracking the time we entered EMLSR, and in the worker make
sure that 5 seconds passed from when we entered EMLSR. If not, don't

Move the iwl_trans_pcie_dump_regs() function to utils.c in the PCIe
directory since it operates on PCIe registers and is not
hardware-dependent.
Refactor the pcie_dbg_dumped_once indicator, previously part of the
iwl_trans_pcie struct, into a static variable within the
iwl_trans_pcie_dump_regs() function, where it is used.
