Input: drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-05-13T22:43:19+00:00

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

Input: Switch i2c drivers back to use .probe()

2023-05-17T16:59:11+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

Input: tsc2007 - enable cansleep pendown GPIO

2023-04-03T04:37:49+00:00

When a hard IRQ is triggered, the soft IRQ, which decides if an actual pen down happened, should always be triggered. This enables the usage of "can_sleep" GPIO chips as "pen down" GPIO, as the value is not read during the hard IRQ anymore. This might be the case if the GPIO chip is an expander behind i2c.

.probe_new() doesn't get the i2c_device_id * parameter, so determine that explicitly in the probe function. Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20221118224540.619276-264-uwe@kleine-koenig.org Signed-off-by: Dmitry Torokhov

Input: tsc2007 - make use of device properties

2021-03-16T00:12:04+00:00

Device property API allows to gather device resources from different sources, such as ACPI. Convert the drivers to unleash the power of device property API.

Input: tsc2007 - convert to GPIO descriptors

2021-03-16T00:12:02+00:00

This converts the driver to use GPIO descriptors. Note that it now uses logical polarity and thus nagation has been dropped. Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20210314210951.645783-1-andy.shevchenko@gmail.com Signed-off-by: Dmitry Torokhov

Input: tsc2007 - correctly report pressure and not resistance to user space

2017-02-23T07:55:09+00:00

Previously, tsc2007 would report as ABS_PRESSURE: 0 for no pressure (resistance infinite) high value for soft pressure (high resistance) low value for firm pressure (lower resistance) This does not matter for most applications (e.g. GUI, Menu, Scrolling etc.) where the ABS_PRESSURE is ignored and only BTN_TOUCH is processed to detect screen taps. Only some special graphics applications read the pressure channel and they will be mixed up by this non-monotonic relation. So we fix it to become: 0 for no pressure (resistance infinite) low value for soft pressure (high resistance) high value for firm pressure (lower resistance) While this patch changes the values reported to userspace, ABS_PRESSURE is used rarely by userspace. Most software only relies on BTN_TOUCH (boolean), which is not affected by this patch. Some graphics software makes use of the interface and does not work correctly with the currently used inverted behaviour. Signed-off-by: H.
