When building kernels without ACPI support the table is declared
but is not used because ACPI_PTR() turns it into a NULL.
Add the __maybe_unused attribute to stop the compiler whining.

This is a simple conversion. Both iio_device_register() and
iio_triggered_buffer_setup() functions have device-managed variants.

There is nothing else that needs to be done for this driver. The remove
hook calls only the iio_device_unregister() hook.
So this driver can use devm_iio_device_register() directly.

This change converts the probe of the AD5064 driver to use only
device-managed functions.
The regulator_bulk_disable() is passed on a devm_add_action_or_reset() hook
and the devm_iio_device_register() can be used to register the IIO device.
The driver has both I2C and SPI hooks inside, so all these can be removed.

This change does a conversion of the driver to use device-managed init
functions. The 2 regulators and the clock inits are converted to use
devm_add_action_or_reset() callbacks for de-initializing them when the
driver unloads.
And finally the devm_iio_device_register() function can be use to register
the device.
The remove hook can finally be removed and the spi_set_drvdata() call can
also be removed as the private data is no longer used.

For this conversion, the regulators need to have some cleanup hooks
registered with devm_add_action_or_reset() and then the
devm_io_device_register() call can be used.

The LSI/CSI LS7266R1 chip provides programmable output via the FLG pins.
When interrupts are enabled on the ACCES 104-QUAD-8, they occur whenever
FLG1 is active. Four functions are available for the FLG1 signal: Carry,
Compare, Carry-Borrow, and Index.
Carry:
Interrupt generated on active low Carry signal. Carry
signal toggles every time the respective channel's
counter overflows.
Compare:
Interrupt generated on active low Compare signal.
Compare signal toggles every time respective channel's
preset register is equal to the respective channel's
counter.
Carry-Borrow:
Interrupt generated on active low Carry signal and
active low Borrow signal. Carry signal toggles every
time the respective channel's counter overflows. Borrow
signal toggles every time the respective channel's
counter underflows.
Index:
Interrupt generated on active high Index signal.
These four functions correspond respectivefly to the following four
Counter event types: COUNTER_EVENT_OVERFLOW, COUNTER_EVENT_THRESHOLD,
COUNTER_EVENT_OVERFLOW_UNDERFLOW, and COUNTER_EVENT_INDEX. Interrupts
push Counter events to event channel X, where 'X' is the respective
channel whose FLG1 activated.
This patch adds IRQ support for the ACCES 104-QUAD-8. The interrupt line
numbers for the devices may be configured via the irq array module
parameter.

This patch replaces the mutex I/O lock with a spinlock. This is in
preparation for a subsequent patch adding IRQ support for 104-QUAD-8
devices; we can't sleep in an interrupt context, so we'll need to use a
spinlock instead.

The events_queue_size sysfs attribute provides a way for users to
dynamically configure the Counter events queue size for the Counter
character device interface. The size is in number of struct
counter_event data structures. The number of elements will be rounded-up
to a power of 2 due to a requirement of the kfifo_alloc function called
during reallocation of the queue.

This patch introduces a character device interface for the Counter
subsystem. Device data is exposed through standard character device read
operations. Device data is gathered when a Counter event is pushed by
the respective Counter device driver. Configuration is handled via ioctl
operations on the respective Counter character device node.

This is a reimplementation of the Generic Counter driver interface.
There are no modifications to the Counter subsystem userspace interface,
so existing userspace applications should continue to run seamlessly.
The purpose of this patch is to internalize the sysfs interface code
among the various counter drivers into a shared module. Counter drivers
pass and take data natively (i.e. u8, u64, etc.) and the shared counter
module handles the translation between the sysfs interface and the
device drivers. This guarantees a standard userspace interface for all
counter drivers, and helps generalize the Generic Counter driver ABI in
order to support the Generic Counter chrdev interface (introduced in a
subsequent patch) without significant changes to the existing counter
drivers.
Note, Counter device registration is the same as before: drivers
populate a struct counter_device with components and callbacks, then
pass the structure to the devm_counter_register function. However,
what's different now is how the Counter subsystem code handles this
registration internally.
Whereas before callbacks would interact directly with sysfs data, this
interaction is now abstracted and instead callbacks interact with native
C data types. The counter_comp structure forms the basis for Counter
extensions.
The counter-sysfs.c file contains the code to parse through the
counter_device structure and register the requested components and
extensions. Attributes are created and populated based on type, with
respective translation functions to handle the mapping between sysfs and
the counter driver callbacks.
The translation performed for each attribute is straightforward: the
attribute type and data is parsed from the counter_attribute structure,
the respective counter driver read/write callback is called, and sysfs
I/O is handled before or after the driver read/write function is called.

In read_domain_devices(), acpi_bus_get_device() is called to obtain
the ACPI device object attached to the given ACPI handle and
subsequently that object is passed to get_device() for reference
counting, but there is a window between the acpi_bus_get_device()
and get_device() calls in which the ACPI device object in question
may go away.
To address this issue, make read_domain_devices() use
acpi_bus_get_acpi_device() to reference count and return the given
ACPI device object in one go and export that function to modules.
While at it, also make read_domain_devices() and
remove_domain_devices() use acpi_dev_put() instead of calling
put_device() directly on the ACPI device objects returned by
acpi_bus_get_acpi_device().

The ili251x firmware can be updated, this is used when switching between
different modes of operation of the touch surface, e.g. glove operation.
This patch implements the firmware update mechanism triggered by a write
into an sysfs attribute.
The firmware itself is distributed as an intel hex file with non-standard
types. The first two lines are of type 0xad, which indicates the start of
DataFlash payload, that is always at address 0xf000 on the ili251x, so it
can be dropped, and 0xac which indicates the position of firmware info in
the Application payload, that is always at address 0x2020 on the ili251x
and we do not care. The rest of the firmware is data of type 0x00, and we
care about that. To convert the firmware hex file into something usable
by the kernel, remove the first two lines and then use ihex2fw:
$ tail -n +3 input.hex > temp.hex
$ ./tools/firmware/ihex2fw temp.hex firmware/ilitek/ili251x.bin
To trigger the firmware update, place firmware file ilitek/ili251x.bin
into /lib/firmware/, write into firmware_update sysfs attribute and wait
about 30-40 seconds. The firmware update is slow. Afterward, verify the
firmware_version and mode sysfs attributes to check whether the firmware
got updated and the controller switched back to application (AP) mode by
reading out 'mode' attribute in sysfs.
Note that the content of firmware_version, e.g. 0600.0005.abcd.aa04 can
be matched to the content of the firmware hex file. The first four bytes,
0x06 0x00 0x00 0x05 can be found at ^:102030 00 05000006, the next four
bytes 0xab 0xcd 0xaa 0x04 at ^:10F000 00 nnnnnnnn ABCDAA04.
Note that the protocol differs considerably between the ili2xxx devices,
this patch therefore implements this functionality only for ili251x that
I can test.

The ili251x firmware protocol permits readout of firmware version,
protocol version, mcu version and current mode (application, boot
loader, forced update). These information are useful when updating
the firmware on the il251x, e.g. to avoid updating the same firmware
into the device multiple times. The locking is now necessary to avoid
races between interrupt handler and the sysfs readouts.

The ili251x firmware protocol permits readout of panel resolution,
implement this, but make it possible to override this value using
DT bindings. This way, older DTs which contain touchscreen-size-x
and touchscreen-size-y properties will behave just like before and
new DTs may avoid specifying these for ILI251x.
Note that the command format is different on other controllers, so
this functionality is isolated to ILI251x.

When scanning devices through the 'scan' attribute in sysfs, the user will
observe duplicate device entries in lsscsi command output.
Set the shost's max_channel to zero to avoid this.

We are using devm_input_allocate_device() that already sets parent
of the input device, there is no need to do that again.

All SCSI drivers have been converted to use shost_groups and sdev_groups
instead of shost_attrs or sdev_attrs. Hence remove shost_attrs and
sdev_attrs. Additionally, remove the 'lld_attr_group' members and also
the scsi_convert_dev_attrs() function.
