| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We should not be forcing edge triggered interrupt, but rather let platform decide the kind of trigger it needs to use. Also, the driver is not quite safe with regard to edge-triggered interrupts as it does not try to kick the controller after requesting/enabling IRQ.

* | | Input: ar1021_i2c - fix too long name in driver's device tableDmitry Torokhov2017-04-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The name field in structure i2c_device_id is 20 characters, and we expect it to be NULL-terminated, however we are trying to stuff it with 21 bytes and thus NULL-terminator is lost. This causes issues when one creates device with name "MICROCHIP_AR1021_I2C" as i2c core cuts off the last "C", and automatic module loading by alias does not work as result. The -I2C suffix in the device name is superfluous, we know what bus we are dealing with, so let's drop it. Also, no other driver uses capitals, and the manufacturer name is normally not included, except in very rare cases of incompatible name collisions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF. As pointed by Hans de Goede, there's no mssl1680 and this is just used in some ACPI systems to identify the gsl1680 chip. So isn't included in the OF device ID table since a DT should use the proper device name instead.

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.

Since it is not wasting much resources and is very straightforward, we simply provide all other adc channels as optional iio interfaces as weel. This can be used for debugging or special applications.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gpiochip_add now has a managed version, and we can remove sysfs attribute group via devm_add_action_or_reset (at least until we have devm version of sysfs_create_group). This allows us to get rid of ad7879_remove().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed. But in order to change how the core reports modaliases to user-space, it's better to export it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of supporting legacy platform data (of which we have no mainline users) and OF-based properties, let's switch to generic device properties. This will still allow legacy boards to use the driver (by defining property sets and attaching them to the drivers) and will simplify probe and make driver usable on ACPI-based systems as well.
