| | | | | | | | | | | | | | | | | | | | platform_device_id are not supposed to change at runtime. All functions working with platform_device_id provided by <linux/platform_device.h> work with const platform_device_id. So mark the non-const structs as const.

* HID: sensor: fix attributes in HID sensor interfaceOoi, Joyce2016-11-051-3/+3
| | | | | | | | | | | | | | | | | | | User is unable to access to input-X-yyy and feature-X-yyy where X is a hex value and more than 9 (e.g. input-a-yyy, feature-b-yyy) in HID sensor custom sysfs interface. This is because when creating the attribute, the attribute index is written to using %x (hex). However, when reading and writing values into the attribute, the attribute index is scanned using %d (decimal). Hence, user is unable to access to attributes with index in hex values (e.g. 'a', 'b', 'c') but able to access to attributes with index in decimal values (e.g. 1, 2, 3,..). This fix will change input-%d-%x-%s and feature-%d-%x-%s to input-%x-%x-%s and feature-%x-%x-%s in show_values() and store_values() accordingly.

* HID: sensor: Custom and Generic sensor supportSrinivas Pandruvada2015-04-101-0/+849
HID Sensor Spec defines two usage ids for custom sensors HID_USAGE_SENSOR_TYPE_OTHER_CUSTOM (0x09, 0xE1) HID_USAGE_SENSOR_TYPE_OTHER_GENERIC(0x09, 0xE2) In addition the standard also defines usage ids for custom fields. The purpose of these sensors is to extend the functionality or provide a way to obfuscate the data being communicated by a sensor. Without knowing the mapping between the data and its encapsulated form, it is difficult for an driver to determine what data is being communicated by the sensor. This allows some differentiating use cases, where vendor can provide applications. Since these can't be represented by standard sensor interfaces like IIO, we present these as fields with - type (input/output) - units - min/max - get/set value In addition an dev interface to transfer report events. Details about this interface is described in /Documentation/hid/hid-sensor.txt. Manufacturers should not use these ids for any standard sensors, otherwise the the product/vendor id can be added to black list.
