Move offset_uv in struct ada4250_state. This keeps things logically

Only print an information message instead of error message and failing
to probe the device if the chip ID is not recognized. Experience shows
that this can be fragile and some devices may not return the expected
chip ID even though the driver is still able to work with them.

Refactor the apds9306_event_thresh_get() and apds9306_event_thresh_set()
functions to use a helper function (apds9306_get_thresh_reg()) for
obtaining the correct register based on the direction of the event. This
improves code readability and maintains consistency in accessing
threshold registers.

Separate filter type and decimation rate from the sampling frequency
attribute. The new filter type attribute enables sinc3, sinc3+rej60
and wideband filters, which were previously unavailable.
Previously, combining decimation and MCLK divider in the sampling
frequency obscured performance trade-offs. Lower MCLK divider
settings increase power usage, while lower decimation rates reduce
precision by decreasing averaging. By creating an oversampling
attribute, which controls the decimation, users gain finer control
over performance.
The addition of those attributes allows a wider range of sampling
frequencies and more access to the device features. Sampling frequency
table is updated after every digital filter parameter change.
Changes in the sampling frequency are not allowed anymore while in
buffered mode.

The synchronization method using GPIO requires the generated pulse to be
truly synchronous with the base MCLK signal. When it is not possible to
do that in hardware, the datasheet recommends using synchronization over
SPI, where the generated pulse is already synchronous with MCLK. This
requires the SYNC_OUT pin to be connected to the SYNC_IN pin.
Use trigger-sources property to enable device synchronization over SPI
and multi-device synchronization while replacing sync-in-gpios property.

When the device is configured to decimation x8, only possible in the
sinc5 filter, output data is reduced to 16 bits in order to support
1 MHz of sampling frequency due to clock limitation.
Use multiple scan types feature to enable the driver to switch
scan type at runtime, making it possible to support both 24-bit and
16-bit resolution.

The AD7768-1 has the ability to control other local hardware (such as gain
stages),to power down other blocks in the signal chain, or read local
status signals over the SPI interface.
Add direct mode conditional locks in the GPIO callbacks to prevent register
access when the device is in buffered mode.
This change exports the AD7768-1's four GPIOs and makes them accessible
at an upper layer.

When memory allocation fails during creating the name of the nodes in
icc_clk_register(), the code continues on the error path and it calls
icc_nodes_remove() to destroy the already created nodes. However that
function only destroys the nodes which were already added to the provider
and the newly created nodes are never destroyed in case of error.
In order to avoid a memory leaks, change the code to destroy the newly
created nodes explicitly in case of memory allocation failures.

Since commit d30f83d278a9 ("interconnect: core: Add dynamic id allocation
support"), interconnect node ids greater than or equal to ICC_DYN_ID_START
are reserved for dynamic id allocation. Yet the icc_node_create_nolock()
function allows to directly use such ids for creating nodes. This can
cause problems by executing dynamic id related codepaths even for nodes
intended to use static ids.
For example, the 'nsscc-ipq9574' driver creates interconnect nodes with
static ids starting from 19148. Because these ids belongs to the dynamic
id range, the icc_node_add() function replaces the node names
unexpectedly.
The node names looked like this before the change:
# grep nss_cc /sys/kernel/debug/interconnect/interconnect_summary
nss_cc_nssnoc_ppe_clk_master 0 0
nss_cc_nssnoc_ppe_clk_slave 0 0
nss_cc_nssnoc_ppe_cfg_clk_master 0 0
...
And those have an unexpected suffix now:
# grep nss_cc /sys/kernel/debug/interconnect/interconnect_summary
nss_cc_nssnoc_ppe_clk_master@39b00000.clock-controller 0 0
nss_cc_nssnoc_ppe_clk_slave@39b00000.clock-controller 0 0
nss_cc_nssnoc_ppe_cfg_clk_master@39b00000.clock-controller 0 0
...
Increase the value of ICC_DYN_ID_START to avoid this.
Also, add sanity check to the icc_node_create_nolock() function to prevent
directly creating nodes with ids reserved for dynamic allocation in order
to detect these kind of problems.

Add an operation to populate a part of a drm_mm with device
private memory. Clarify how migration using it is intended
to work.
v3:
- Kerneldoc fixes and updates (Matt Brost).
v4:
- More kerneldoc fixes. Rebase.

The migration functionality and track-keeping of per-pagemap VRAM
mapped to the CPU mm is not per GPU_vm, but rather per pagemap.
This is also reflected by the functions not needing the drm_gpusvm
structures. So move to drm_pagemap.
With this, drm_gpusvm shouldn't really access the page zone-device-data
since its meaning is internal to drm_pagemap. Currently it's used to
reject mapping ranges backed by multiple drm_pagemap allocations.
For now, make the zone-device-data a void pointer.
Alter the interface of drm_gpusvm_migrate_to_devmem() to ensure we don't
pass a gpusvm pointer.
Rename CONFIG_DRM_XE_DEVMEM_MIRROR to CONFIG_DRM_XE_PAGEMAP.
Matt is listed as author of this commit since he wrote most of the code,
and it makes sense to retain his git authorship.
Thomas mostly moved the code around.
v3:
- Kerneldoc fixes (CI)
- Don't update documentation about how the drm_pagemap
migration should be interpreted until upcoming
patches where the functionality is implemented.
(Matt Brost)
v4:
- More kerneldoc fixes around timeslice_ms
(Himal Ghimiray, Matt Brost)
v6:
- Fix an uninitialized pagemap pointer (CI)

The driver currently defaults to the internal oscillator as the clock
source for E825-C hardware. While this clock source is labeled TCXO,
indicating a temperature compensated oscillator, this is only true for some
board designs. Many board designs have a less capable oscillator. The
E825-C hardware may also have its clock source set to the TIME_REF pin.
This pin is connected to the DPLL and is often a more stable clock source.
The choice of the internal oscillator is not suitable for all systems,
especially those which want to enable SyncE support.
There is currently no interface available for users to configure the clock
source. Other variants of the E82x board have the clock source configured
in the NVM, but E825-C lacks this capability, so different board designs
cannot select a different default clock via firmware.
In most setups, the TIME_REF is a suitable default clock source.
Additionally, we now fall back to the internal oscillator automatically if
the TIME_REF clock source cannot be locked.
Change the default clock source for E825-C to TIME_REF. Note that the
driver logs a dev_dbg message upon configuring the TSPLL which includes the
clock source and frequency. This can be enabled to confirm which clock
source is in use.
Longterm a proper interface to dynamically introspect and change the clock
source will be designed (perhaps some extension of the DPLL subsystem?)

TSPLL can fail when trying to lock to TIME_REF as a clock source, e.g.
when the external clock source is not stable or connected to the board.
To continue operation after failure, try to lock again to internal TCXO
and inform user about this.

To ensure proper operation, wait for 10 to 20 microseconds before
enabling TSPLL.
Adjust wait time after enabling TSPLL from 1-5 ms to 1-2 ms.
Those values are empirical and tested on multiple HW configurations.

Switch from unions with bitfield structs to definitions with bitfield
masks. This is necessary, because some registers have different
field definitions or even use a different register for the same fields
