* rtc: hid-sensor-time: Constify platform_device_idKrzysztof Kozlowski2015-06-191-1/+1
| | | | | | | | The platform_device_id is not modified by the driver and core uses it as const. Signed-off-by: Krzysztof Kozlowski <k.kozlowski.k@gmail.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
* HID: hid-sensor-hub: Extend API for async readsSrinivas Pandruvada2015-02-231-1/+1
| | | | | | | | | | | Add additional flag to read in async mode. In this mode the caller will get reply via registered callback for capture_sample. Callbacks can be registered using sensor_hub_register_callback function. The usage id parameter of the capture_sample can be matched with the usage id of the requested attribute.

* rtc: drop owner assignment from platform_driversWolfram Sang2014-10-201-1/+0
| | | | | | | A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
* tree-wide: use reinit_completion instead of INIT_COMPLETIONWolfram Sang2013-11-151-1/+1
| | | | | | | | | | | | Use this new function to make code more comprehensible, since we are reinitialzing the completion, not initializing.

* drivers/rtc/rtc-hid-sensor-time.c: enable HID input processing earlyAlexander Holler2013-11-151-0/+7
| | | | | | | | | | | Enable the processing of HID input records before the RTC will be registered, in order to allow the RTC register function to read clock. Without doing that the clock can only be read after the probe function has finished.

* drivers/rtc/rtc-hid-sensor-time.c: use dev_get_platdata()Jingoo Han2013-11-151-2/+2
| | | | | | | | | | Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. This is a cosmetic change to make the code simpler and enhance the readability.

* HID RTC: Open sensor hub open closeSrinivas Pandruvada2013-10-011-1/+14
| | | | | | | | | | Open sensor hub when module is loaded and close when module is removed. This helps saving power by opening HID transport only when there is an user.

| | | | | | | | | | | | | | | | automatically In order to get the module automatically loaded by hotplug mechanisms a MODULE_DEVICE_TABLE is needed. Therefore add one. This makes it also possible to use a module name other than HID-SENSOR-2000a0 which isn't very descriptive in kernel messages.

* rtc: rtc-hid-sensor-time: allow full years (16bit) in HID reportsAlexander Holler2013-07-031-7/+26
| | | | | | | | | | | | | | | | | | | | | | The draft for HID-sensors (HUTRR39) currently doesn't define the range for the attribute year. Asking one of the authors revealed that full years (e.g. 2013 instead of just 13) were meant. So we now allow both, 8 bit and 16 bit values for the attribute year and assuming full years when the value is 16 bits wide. We will still support 8 bit values until the specification gets final (and maybe defines a way to set the time too).

* rtc: add rtc-driver for HID sensors of type timeAlexander Holler2013-01-061-0/+291
This driver makes the time from HID sensors (hubs) which are offering such available like any other RTC does. It is necessary that all values like year, month etc, are send as 8bit values (1 byte each) and all of them in 1 report. Also the spec HUTRR39b doesn't define the range of the year field, we tread it as 0 - 99 because that's what most RTCs I know about are offering. Currently the time can only be read. Setting the time must be done through sending a report (or a feature). The spec currently doesn't define how and I'm not sure if I just should define something by myself.
