formance low-power audio DSP with analog and
PDM digital inputs and support for low-power always-on voice-trigger
functionality.
This series adds the devicetree bindings and the ASoC codec driver.
Merge series from Bard Liao <yung-chuan.liao@linux.intel.com>:
A codec endpoint may not be used. We could check the present SDCA
functions to know if the endpoint is used or not. Skip the endpoint
which is not used. And load the topology dynamically for each endpoint.
With this feature, we don't need to use the quirk to determine the
existence of the optional codec DAIs.

Remove the suppression of the uevents before scanning for partitions.
The partitions inherit their suppression settings from their parent device,

On malfunctioning hardware, timeout error messages can appear thousands
of times, creating unnecessary system pressure and log bloat. This patch
makes two improvements:
1. Replace dev_err() with dev_err_ratelimited() to prevent log flooding
when hardware errors persist
2. Remove the redundant timeout value parameter from the error message,
as 'ret' is always zero in this error path
These changes reduce logging overhead while maintaining necessary error
reporting for debugging purposes.

Some machines with tegra_qspi_combined_seq_xfer hardware issues generate
excessive kernel warnings, severely polluting the logs:

occurrence, providing sufficient information about the failure, while
the stack trace is only needed once for debugging purposes.

GNU Make 4.3 changed the behavior of `#` inside commands in commit
c6966b323811 ("[SV 20513] Un-escaped # are not comments in function
invocations"):
* WARNING: Backward-incompatibility!
Number signs (#) appearing inside a macro reference or function invocation
no longer introduce comments and should not be escaped with backslashes:
thus a call such as:
foo := $(shell echo '#')
is legal. Previously the number sign needed to be escaped, for example:
foo := $(shell echo '\#')
Now this latter will resolve to "\#". If you want to write makefiles
portable to both versions, assign the number sign to a variable:
H := \#
foo := $(shell echo '$H')
This was claimed to be fixed in 3.81, but wasn't, for some reason.
To detect this change search for 'nocomment' in the .FEATURES variable.
Unlike other commits in the kernel about this issue, such as commit
633174a704 ("lib/raid6/test/Makefile: Use $(pound) instead of \#
for Make 4.3"), that fixed the issue for newer GNU Makes, in our case
it was the opposite, i.e. we need to fix it for the older ones: someone
building with e.g. 4.2.1 gets the following error:
scripts/Makefile.compiler:81: *** unterminated call to function 'call': missing ')'. Stop.
Thus use the existing variable to fix it.

Add a sysfs knob to enable/disable C1 demotion for the following Intel
platforms: Sapphire Rapids Xeon, Emerald Rapids Xeon, Granite Rapids Xeon,
Sierra Forest Xeon, and Grand Ridge SoC.
This sysfs file shows up as
"/sys/devices/system/cpu/cpuidle/intel_c1_demotion".
The C1 demotion feature involves the platform firmware demoting deep
C-state requests from the OS (e.g., C6 requests) to C1. The idea is
that firmware monitors CPU wake-up rate, and if it is higher than a
platform-specific threshold, the firmware demotes deep C-state
requests to C1. For example, Linux requests C6, but firmware noticed
too many wake-ups per second, and it keeps the CPU in C1. When the
CPU stays in C1 long enough, the platform promotes it back to C6.
The default value for C1 demotion is whatever is configured by BIOS.

gcc 15 honors the __counted_by(len) attribute on vsc_tp_packet.buf[]
and the vsc-tp.c code is using this in a wrong way. len does not contain
the available size in the buffer, it contains the actual packet length
*without* the crc. So as soon as vsc_tp_xfer() tries to add the crc to
buf[] the fortify-panic handler gets triggered:
[ 80.842193] memcpy: detected buffer overflow: 4 byte write of buffer size 0

The easiest fix would be to just drop the counted-by but with the exception
of the ack buffer in vsc_tp_xfer_helper() which only contains enough room
for the packet-header, all other uses of vsc_tp_packet always use a buffer
of VSC_TP_MAX_XFER_SIZE bytes for the packet.
Instead of just dropping the counted-by, split the vsc_tp_packet struct
definition into a header and a full-packet definition and use a fixed
size buf[] in the packet definition, this way fortify-source buffer
overrun checking still works when enabled.

Convert the Ingenic glue driver to use the generic stmmac platform

In order to do this, we need to make ingenic_mac_init() arguments
compatible with plat_dat->init() by adding a plat_dat member to struct
ingenic_mac. This allows the custom suspend/resume operations to be
removed, and the PM ops pointer replaced with stmmac_pltfr_pm_ops.
This will adds runtime PM and noirq suspend/resume ops to this driver.

Using stmmac_pltfr_probe() simplifies the probe function. This will not
only call plat_dat->init (imx_dwmac_init), but also plat_dat->exit
(imx_dwmac_exit) appropriately if stmmac_dvr_probe() fails. This
results in an overall simplification of the glue driver.

Russell King says:
====================
net: stmmac: anarion: cleanups
A series of cleanups to the anarion glue driver.
Clean up anarion_config_dt() error handling, printing a human readable
error rather than the numeric errno, and use ERR_CAST().
Using a switch statement with incorrect "fallthrough;" for RGMII vs
non-RGMII is unnecessary when we have phy_interface_mode_is_rgmii().
Convert to use the helper.
Use stmmac_pltfr_probe() rahter than open-coding the call to the
init function (which stmmac_pltfr_probe() will do for us.)
Finally, convert to use devm_stmmac_pltfr_probe() which allows the
removal of the .remove initialiser in the driver structure.
Not tested on hardware.

Convert anarion to use devm_stmmac_pltfr_probe() which allows the
removal of an explicit call to stmmac_pltfr_remove().

Rather than open-coding the call to anarion_gmac_init() and then
stmmac_dvr_probe(), omitting the cleanup of calling
anarion_gmac_exit(), use stmmac_pltfr_probe() which will handle this
for us.
