Arnd Bergmann 0ae41a0b53 input: omap: void using mach/*.h headers
The omap-keypad driver currently relies on including mach/memory.h
implicitly, but that won't happen once omap1 is converted to
CONFIG_ARCH_MULTIPLATFORM. Include the required header
explicitly.

Miaoqian Lin 81022a1704 Input: omap4-keypad - fix pm_runtime_get_sync() error checking
If the device is already in a runtime PM enabled state
pm_runtime_get_sync() will return 1, so a test for negative
value should be used to check for errors.

AngeloGioacchino Del Regno db6c4ee783 Input: mt6779-keypad - move iomem pointer to probe function
The mmio base address is used for the only purpose of initializing
regmap for this driver, hence it's not necessary to have it in the
main driver structure, as it is used only in the probe() callback.
Move it local to function mt6779_keypad_pdrv_probe().

This commit brings no functional changes.

Linus Torvalds ad9c6ee642 spi: Updates for v5.18
The overwhelming bulk of this pull request is a change from Uwe
 Kleine-König which changes the return type of the remove() function to
 void as part of some wider work he's doing to do this for all bus types,
 causing updates to most SPI device drivers.  The branch with that on has
 been cross merged with a couple of other trees which added new SPI
 drivers this cycle, I'm not expecting any build issues resulting from
 the change.
 
 Otherwise it's been a relatively quiet release with some new device
 support, a few minor features and the welcome completion of the
 conversion of the subsystem to use GPIO descriptors rather than numbers:
 
  - Change return type of remove() to void.
  - Completion of the conversion of SPI controller drivers to use GPIO
    descriptors rather than numbers.
  - Quite a few DT schema conversions.
  - Support for multiple SPI devices on a bus in ACPI systems.
  - Big overhaul of the PXA2xx SPI driver.
  - Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
    MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
    Sunplus SP7021.

Stephen Boyd 45ceaf14d5 Input: extract ChromeOS vivaldi physmap show function
Let's introduce a common library file for the physmap show function
duplicated between three different keyboard drivers. This largely copies
the code from cros_ec_keyb.c which has the most recent version of the
show function, while using the vivaldi_data struct from the hid-vivaldi
driver. This saves a small amount of space in an allyesconfig build.

spi: make remove callback a void function
The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Mattijs Korpershoek f4e09e8bfd Input: mtk-pmic-keys - use get_irq_byname() instead of index
Some pmics of the mt6397 family (such as MT6358), have two IRQs per
physical key: one for press event, another for release event.

The mtk-pmic-keys driver assumes that each key only has one
IRQ. The key index and the RES_IRQ resource index have a 1/1 mapping.

This won't work for MT6358, as we have multiple resources (2) for one key.

To prepare mtk-pmic-keys to support MT6358, retrieve IRQs by name
instead of by index.

Uwe Kleine-König d997cc1715 Input: snvs_pwrkey - add clk handling
On i.MX7S and i.MX8M* (but not i.MX6*) the pwrkey device has an
associated clock. Accessing the registers requires that this clock is
enabled. Binding the driver on at least i.MX7S and i.MX8MP while not
having the clock enabled results in a complete hang of the machine.
(This usually only happens if snvs_pwrkey is built as a module and the
rtc-snvs driver isn't already bound because at bootup the required clk
is on and only gets disabled when the clk framework disables unused clks
late during boot.)

This completes the fix in commit 135be16d35 ("ARM: dts: imx7s: add
snvs clock to pwrkey").

Stephan Gerhold 872e57abd1 Input: tm2-touchkey - allow changing keycodes from userspace
At the moment the touch keys have key codes assigned from the device
tree. In some cases, users might want to change the key code from
userspace. There is existing functionality for this in the input core
using the EVIOCSKEYCODE ioctl, which is integrated for example into udev.

Make it possible to use this functionality for tm2-touchkey by simply

Report the index of pressed touch key as MSC_SCAN code to userspace
so it is possible to identify which of the keys was pressed (not
just the function that is currently assigned to the key).

This is done similarly also in mcs_touchkey and mpr121_touchkey.

Len Baker cef6f5cc14 Input: omap-keypad - prefer struct_size over open coded arithmetic
As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.

So, use the struct_size() helper to do the arithmetic instead of the
argument "size + count * size" in the kzalloc() function.

The only function that could return a non-zero value before was
ipmi_parisc_remove() which returns the return value of
ipmi_si_remove_by_dev(). Make this function return void, too, as for all
other callers the value is ignored, too.

Paul Cercueil c9efb0ba28 Input: gpio-keys - use hrtimer for software debounce, if possible
We want to be able to report the input event as soon as the debounce
delay elapsed. However, the current code does not really ensure that,
as it uses the jiffies-based schedule_delayed_work() API. With a small
enough HZ value (HZ <= 100), this results in some input events being
lost, when a key is quickly pressed then released (on a human's time
scale).

Switching to hrtimers fixes this issue, and will work even on extremely
low HZ values (tested at HZ=24). This is however only possible if
reading the GPIO is possible without sleeping. If this condition is not
met, the previous approach of using a jiffies-based timer is taken.

Paul Cercueil 019002f20c Input: gpio-keys - use hrtimer for release timer
Dealing with input, timing is important; if the button should be
released in one millisecond, then it should be done in one millisecond
and not a hundred milliseconds.

Therefore, the standard timer API is not really suitable for this task.

Convert the gpio-keys driver to use a hrtimer instead of the standard
timer to address this issue.

Note that by using a hard IRQ for the hrtimer callback, we can get rid
of the spin_lock_irqsave() and spin_unlock_irqrestore().

Fabian Vogt 69d5ff3e9e Input: nspire-keypad - enable interrupts only when opened
The driver registers an interrupt handler in _probe, but didn't configure
them until later when the _open function is called. In between, the keypad
can fire an IRQ due to touchpad activity, which the handler ignores. This
causes the kernel to disable the interrupt, blocking the keypad from
working.

Fix this by disabling interrupts before registering the handler.
Additionally, disable them in _close, so that they're only enabled while
open.

Philip Chen 820c872795 Input: cros-ec-keyb - expose function row physical map to userspace
The top-row keys in a keyboard usually have dual functionalities.
E.g. A function key "F1" is also an action key "Browser back".

Therefore, when an application receives an action key code from
a top-row key press, the application needs to know how to correlate
the action key code with the function key code and do the conversion
whenever necessary.

Since the userpace already knows the key scanlines (row/column)
associated with a received key code. Essentially, the userspace only
needs a mapping between the key row/column and the matching physical
location in the top row.

So, enhance the cros-ec-keyb driver to create such a mapping
and expose it to userspace in the form of a function_row_physmap
attribute. The attribute would be a space separated ordered list of
row/column codes for the keys in the function row, in a left-to-right
order.

The attribute will only be present when the device has a custom design
for the top-row keys.

Ronald Tschalär e64123949e Input: applespi - fix occasional crc errors under load.
For some reason, when the system is under heavy CPU load, the read
following the write sometimes occurs unusually quickly, resulting in
the read data not being quite ready and hence a bad packet getting read.
Adding another delay after reading the status message appears to fix
this.

The response to a command may never arrive or it may be corrupted (and
hence dropped) for some reason. While exceedingly rare, when it did
happen it blocked all further commands. One way to fix this was to
do a suspend/resume. However, recovering automatically seems like a
nicer option. Hence this puts a time limit (1 sec) on how long we're
willing to wait for a response, after which we assume it got lost.

Tony Lindgren 2f6aa61d87 Input: omap4-keypad - implement errata check for lost key-up events
We are still missing handling for errata i689 related issues for the
case where we never see a key up interrupt for the last pressed key.

To fix the issue, we must scan the key state again after the keyboard
controller has idled to check if a key up event was missed. This is
described in the omap4 silicon errata documentation for Errata ID i689
"1.32 Keyboard Key Up Event Can Be Missed":

"When a key is released for a time shorter than the debounce time,
 in-between 2 key press (KP1 and KP2), the keyboard state machine will go
 to idle mode and will never detect the key release (after KP1, and also
 after KP2), and thus will never generate a new IRQ indicating the key
 release."

We can use PM runtime autosuspend features to check the keyboard state
after it enters idle.

Tony Lindgren 905dbf1d39 Input: omap4-keypad - scan keys in two phases and simplify with bitmask
Because of errata i689 the keyboard can idle with state where no key
up interrupts are seen until after the next key press.

This means we need to first check for any lost key up events before
scanning for new down events.

For example, rapidly pressing shift-shift-j can sometimes produce a J
instead of j. Let's fix the issue by scanning the keyboard in two
phases. First we scan for any key up events that we may have missed,
and then we scan for key down events.

  2) In err_unmap, forget to disable runtime of device,

  3) In err_pm_disable, it will call pm_runtime_put_sync twice not

Alexandru Ardelean 30df385e35 Input: adp5589-keys - use devm_add_action_or_reset() for register clear
The driver clears the general configuration register during the remove()
hook. This should also be done in case the driver exits on error.

This change move the clear of that register to the
devm_add_action_or_reset() hook.

This change makes use of the devm_gpiochip_add_data() function. With this
the gpiochip_remove() function can be removed, and the
adp5589_gpio_remove() function as well.

The kpad->export_gpio variable is also redundant now, and has been removed.

Alexandru Ardelean 3b95bc57c8 Input: adp5589-keys - remove setup/teardown hooks for gpios
This is currently just dead code. It's from around a time when
platform-data was used, and a board could hook it's own special callback
for setup/teardown, and a private object (via 'context').

This change removes it, as there are no more users in mainline for this.

Alexandru Ardelean 760a1219ff Input: adp5589-keys - use device-managed function in adp5589_keypad_add()
This change makes use of the devm_input_allocate_device() function, which
gets rid of the input_free_device() and input_unregister_device() calls.

When a device is allocated via input_allocate_device(), the
input_register_device() call will also be device-managed, so there is no
longer need to manually call unregister.

Also, the irq is allocated with the devm_request_threaded_irq(), so with
these two changes, the adp5589_keypad_remove() function is no longer
needed.

This cleans up the error & exit paths.
