Input: pm8941-powerkey - fix debounce on gen2+ PMICs

2023-07-11T17:39:39+00:00

[ Upstream commit 8c9cce9cb81b5fdc6e66bf3f129727b89e8daab7 ]

Since PM8998/PM660, the power key debounce register was redefined to
support shorter debounce times. On PM8941 the shortest debounce time
(represented by register value 0) was 15625us, on PM8998 the shortest
debounce time is 62us, with the default being 2ms.

Adjust the bit shift to correctly program debounce on PM8998 and newer.

Input: adxl34x - do not hardcode interrupt trigger type

2023-07-11T17:39:34+00:00

[ Upstream commit e96220bce5176ed2309f77f061dcc0430b82b25e ]

Instead of hardcoding IRQ trigger type to IRQF_TRIGGER_HIGH, let's
respect the settings specified in the firmware description.

Input: drv260x - sleep between polling GO bit

2023-07-11T17:39:32+00:00

[ Upstream commit efef661dfa6bf8cbafe4cd6a97433fcef0118967 ]

When doing the initial startup there's no need to poll without any
delay and spam the I2C bus.

Let's sleep 15ms between each attempt, which is the same time as used
in the vendor driver.

Input: soc_button_array - add invalid acpi_index DMI quirk handling

2023-06-28T09:14:20+00:00

[ Upstream commit 20a99a291d564a559cc2fd013b4824a3bb3f1db7 ]

Some devices have a wrong entry in their button array which points to
a GPIO which is required in another driver, so soc_button_array must
not claim it.

A specific example of this is the Lenovo Yoga Book X90F / X90L,
where the PNP0C40 home button entry points to a GPIO which is not
a home button and which is required by the lenovo-yogabook driver.

Add a DMI quirk table which can specify an ACPI GPIO resource index which
should be skipped; and add an entry for the Lenovo Yoga Book X90F / X90L
to this new DMI quirk table.

Input: iqs626a - drop unused device node references

2023-02-04T01:21:04+00:00

Each call to device/fwnode_get_named_child_node() must be matched
with a call to fwnode_handle_put() once the corresponding node is
no longer in use. This ensures a reference count remains balanced
in the case of dynamic device tree support.

Currently, the driver never calls fwnode_handle_put(); this patch
adds the missing calls. Because fwnode_handle_put() does not take
a const *fwnode_handle, the const qualifier is removed across all
corresponding *fwnode_handle instances.

As part of this change, trackpad channel touch thresholds and ATI
base values are now specified under single trackpad channel child
nodes. This enhancement moves both properties to scalar values as
opposed to arrays, making their types consistent across bindings.

Input: wistron_btns - use pm_sleep_ptr() to allow removal of ifdef CONFIG_PM guards

2023-01-27T22:49:53+00:00

As the guards only apply to suspend and resume, #ifdef CONFIG_PM_SLEEP
would have been a tighter protection. As pm_sleep_ptr() lets the compiler
see the protected ops structure and callbacks but also lets the compiler
remove it as unused code if !CONFIG_PM_SLEEP this allows the #ifdef
guards to be removed, slightly simplifying the resulting code.

--
It seems likely that DEFINE_SIMPLE_DEV_PM_OPS() would work here but
I'd prefer not to make that change unless someone can confirm that the
extra callbacks registered will have no unwanted side effects in this
driver.

Input: adxl34x - unify dev_pm_ops using EXPORT_SIMPLE_DEV_PM_OPS()

2023-01-27T22:49:53+00:00

The I2C and SPI PM callbacks were identical (though wrapped in some
bouncing out to the bus specific container of the struct device and
then back again to get the drvdata).  As such rather than just moving
these to SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() take the opportunity
to unify the struct dev_pm_ops and use the new EXPORT_SIMPLE_DEV_PM_OPS()
macro so that we can drop the unused suspend and resume callbacks as well
as the structure if !CONFIG_PM_SLEEP without needing to mark the callbacks
__maybe_unused.
