The TCS3472 has a wait state controlled by the WEN bit in the ENABLE
register and the WAIT register, with an additional WLONG bit in CONFIG
that if set multiplies the wait step by 12. The driver previously
defined TCS3472_WTIME but never used it leaving the TODO comment on
the top of the source file.
Implement control of the wait time through IIO_CHAN_INFO_SAMP_FREQ:
- Reading sampling_frequency returns the chip's current cycle time,
computed as the sum of ATIME, the fixed RGBC initialization time
and the wait time (which depends on WEN and WLONG).
- Writing sampling_frequency programs WTIME so that the resulting
cycle period approximates the requested frequency. If the
requested frequency cannot be reached with any
non-zero wait time, WEN is disabled and the chip runs
back-to-back conversions at the maximum rate allowed by ATIME.
If the requested period exceeds the maximum WTIME range, WLONG
is enabled to extend the wait step from 2.4 ms to 28.8 ms.
- The user's last requested frequency is stored in the driver's
private data so that subsequent changes to integration_time
recompute WTIME and preserve the requested sampling rate as
closely as possible.
Add TCS3472_ENABLE_WEN, TCS3472_ENABLE_RUN and TCS3472_CONFIG_WLONG
bit definitions. TCS3472_ENABLE_RUN bundles the bits
(AEN | PON | WEN) that are simultaneously set when the chip is in
running state and cleared during powerdown, and is used by
tcs3472_probe(), tcs3472_powerdown().
Add a u8 enable_pre_suspend field to struct tcs3472_data:
tcs3472_powerdown() snapshots data->enable into it, and
tcs3472_resume() restores enable register content from the snapshot.
This preserves the user's WEN choice across suspend/resume.
Bound tcs3472_req_data() polling to the worst-case cycle time
(~8 seconds with ATIME=0x00, WTIME=0x00, WLONG=1).
Fix the event period calculation in tcs3472_read_event() and
tcs3472_write_event() to use tcs3472_cycle_time_us() instead of
ATIME alone. With WEN enabled, the chip cycle includes the wait
time now.

So the PWRMD field in CNFG1_LDO is both the enable bit and the mode.
You can't change one without stepping on the other.
The problem is that enable() from the regulator core just writes
enable_mask (which is PWRMD_NORMAL). If you'd called set_mode(LPM)
then disabled and re-enabled, the mode gets reset to NORMAL. And
set_mode updates the register through the same field, so it can
accidentally enable a disabled regulator.
Fix it by storing the mode in per-regulator data. A custom enable
writes whatever mode was last set. set_mode only touches hardware
if the regulator is already on; otherwise it just caches the value.
Add of_map_mode while here so the initial mode can be wired from DT.

After pm_runtime_enable() the AUDMIX block is powered off and stays
suspended until the first runtime resume. Register writes issued between
probe() and the first resume (e.g. from DAPM or ALSA control paths)
target unpowered hardware and cause a system hang.
Fix this by calling pm_runtime_resume_and_get() immediately after
pm_runtime_enable() to power the hardware up and enable its clocks.
Release the reference afterwards with pm_runtime_put() to allow the
runtime PM framework to suspend the device and switch the regmap to
cache-only mode when idle.
When CONFIG_PM is disabled or runtime PM is not enabled, pm_runtime_*
calls are stubs that do not power up the hardware. Handle this case
explicitly by calling fsl_audmix_runtime_resume() directly so the
hardware is always initialised and its clocks are enabled, ensuring
register accesses succeed regardless of PM configuration.

rt700_sdw_remove() drains jack_detect_work and jack_btn_check_work only
when rt700->hw_init is true. That state bit is cleared by
rt700_update_status() when the SoundWire slave becomes UNATTACHED, but a
jack work item can already have been queued by rt700_interrupt_callback()
or rt700_jack_init() while the device was initialized.
Do not use hw_init as the remove-time guard for draining these work
objects. The delayed works are initialized during rt700_init(), so remove
can cancel them unconditionally and pair the object lifetime with the
codec-private data lifetime instead of a mutable hardware state bit.
This issue was found by our static analysis tool and then confirmed by
manual review of the SoundWire status, interrupt and remove paths. The
remove path should drain work based on whether the work object exists, not
on a runtime hardware state bit that can change after the work was queued.
A QEMU PoC queued jack_detect_work, simulated SDW_SLAVE_UNATTACHED, and
then entered remove. DEBUG_OBJECTS reported an active timer/work object
associated with the rt700 jack work path after remove skipped the cancel.
This is sent as an RFC because the practical trigger depends on SoundWire
core remove ordering after an UNATTACHED status update. If remove cannot
run after hw_init has been cleared while jack work is still pending, this
is a defensive lifecycle cleanup rather than a reachable race on current
systems.

It seems some ARM header includes this and the build passes there, but
nowhere else. Note that the driver has COMPILE_TEST in depends.

aic26_probe() creates the keyclick sysfs file on the component device.
The file callback uses the ASoC component pointer stored in the driver
private data.
There is no matching remove callback, so the sysfs file can remain after
the component is removed while its backing component state is gone.
Add a component remove callback that removes the keyclick file.

sma1303_i2c_probe() creates a sysfs group that exposes the fault-check
controls. The check_fault_status store callback can queue
check_fault_work.
sma1303_i2c_remove() only cancels the delayed work. It does not remove
the sysfs group, so the controls can remain published after remove while
their callbacks still use the driver data and can queue the work again.
Remove the sysfs group before cancelling the delayed work.

If request_irq() fails, report "can not request IRQ" rather than "can
not get IRQ" which may be misread as platform_get_irq() failure.

Even with proper dma engine support, the first spi transfer always
fallback to PIO, the reason is the dws->n_bytes is 0 after
initialization, so the dw_spi_can_dma() calling from __spi_map_msg()
return false, thus both tx_sg_mapped and rx_sg_mapped are false, so
for the first spi transfer, the spi_xfer_is_dma_mapped() reports false
thus fallback to PIO.
Although this brings no harm, we can simply fix this issue by
calcuating the "n_bytes" from xfer->bits_per_word.
