IBI disable failures are not indicative of a software bug, so using
WARN_ON() is not appropriate. Replace these warnings with dev_err().

To prevent inconsistent state when an error occurs, ensure the hot-join

Wait for the bus to fully disable before proceeding, ensuring that no
operations are still in progress. Synchronize the IRQ handler only after
interrupt signals have been disabled. This approach also handles cases
where bus disable might fail, preventing race conditions and ensuring a
consistent shutdown sequence.

The MIPI I3C HCI specification does not define reset values for
RING_OPERATION1 fields, and some controllers (e.g., Intel) do not clear
them during a software reset. Ensure the ring pointers are explicitly
set to zero during bus initialization to avoid inconsistent state.

The Renesas I3C controller does not retain its register state across system
suspend, requiring the driver to explicitly save and restore hardware
configuration.
Add suspend and resume NOIRQ callbacks to handle system sleep transitions.
During suspend, save the Device Address Table (DAT) entries, assert reset
lines, and disable all related clocks to allow the controller to enter a
low-power state.
On resume, re-enable clocks and reset lines in the proper order. Restore
the REFCKCTL register, master dynamic address, and all DAT entries, then
reinitialize the controller.
Store the REFCLK divider value, and the master dynamic address to restore
timing and addressing configuration after resume.

Replace individual devm_clk_get_enabled() calls with the clk_bulk API
and store the clock handles in the driver's private data structure.
All clocks required by the controller are now acquired and enabled using
devm_clk_bulk_get_all_enabled(), removing the need for per-SoC clock
handling and the renesas_i3c_config data.
The TCLK is accessed via a fixed index in the bulk clock array.

Add support for MIPI I3C Host Controllers with the Multi-Bus Instance
capability. These controllers can host multiple I3C buses (up to 15)
within a single hardware function (e.g., PCIe B/D/F), providing one
indepedent HCI register set and corresponding I3C bus controller logic
per bus.
Create an MFD cell for each instance and use platform_data to pass the
starting address of the instance's register set.
The MIPI I3C HCI specification defines an Extended Capability that holds
the offset of each instance register set. Parsing this information is
relatively complex, so include the offsets in driver data for now.
Driver data for additional instances beyond instance 0 will be added in a
subsequent patch.

Simplify the code and ensure names and IDs align with device documentation.
Use explicit device names and IDs for Intel LPSS I3C controllers instead of
dynamically allocated values.
Add "intel-lpss-i3c" to the platform_device_id table in the mipi-i3c-hci
driver and use the same name for Intel I3C controllers in the
mipi_i3c_hci_pci driver. Assign hard-coded IDs to reflect the hardware

Intel SoCs include two I3C PCI devices in the Low Power Subsystem (LPSS),
each supporting up to two I3C buses. The second PCI device is assigned ID 2
(not 1) to match this topology. Additional IDs will be introduced when
Multi-Bus Instance support is implemented.

When I3C is disabled, unused functions are removed by the linker because
the driver relies on regmap and no I3C devices are registered, so normal
I3C paths are never called.
However, some drivers may still call low-level I3C transfer helpers.
Provide stub implementations to avoid adding conditional ifdefs everywhere.
Add stubs for i3c_device_do_xfers() and
i3c_device_get_supported_xfer_mode() only. Other stubs will be introduced
when they are actually needed.

Commit 7bfe3b8ea6e3 ("Drivers: hv: Introduce mshv_vtl driver") added a
new generated header file for the offsets into the mshv_vtl_cpu_context
structure to be used by the low-level assembly code. But it didn't add
the .gitignore file to go with it, so 'git status' and friends will
mention it.
Let's add the gitignore file before somebody thinks that generated
header should be committed.

Pull sound fixes from Takashi Iwai:
"The only slightly large change is the enablement of CIX HD-audio
controller, which took a bit time to be cooked up, while most of other

- Default disablement of the kconfig for decades old pre-release
alsa-lib PCM API; it's only the default config value change, so it
can't lead to any regressions for the existing setups
- Support for CIX HD-audio controller
- A few ASoC ACP fixes
