2016-08-05HID: wacom: EKR: have one array of struct remotes instead of many arraysBenjamin Tissoires3-29/+32
No functional changes, just a prep patch for the one after. Signed-off-by: Benjamin Tissoires <[email protected]> Acked-by: Ping Cheng <[email protected]> Signed-off-by: Jiri Kosina <[email protected]>
2016-08-05HID: wacom: EKR: use devres groups to manage resourcesBenjamin Tissoires1-16/+28
This will be useful when each remote will be assigned its own input device. We won't need to unregister each input and sysfs and other elements one at a time.

2016-08-05HID: wacom: EKR: have proper allocator and destructorBenjamin Tissoires1-40/+53
The wacom_remote_create_attr_group() and wacom_remote_destroy_attr_group() functions were both allocating/destroying the sysfs groups but also initializing the parameters for the remotes.

2016-08-05HID: wacom: rework fail path in probe() and parse_and_register()Benjamin Tissoires1-23/+14

2016-08-05HID: wacom: EKR: have the wacom resources dynamically allocatedBenjamin Tissoires4-66/+94
If we want to have one input device per remote, it's better to have our own struct wacom_remote which is dynamically allocated. Signed-off-by: Benjamin Tissoires <[email protected]> Acked-by: Ping Cheng <[email protected]> Signed-off-by: Jiri Kosina <[email protected]>
2016-08-05HID: wacom: EKR: add a worker to add/remove resources on addition/removalBenjamin Tissoires4-38/+113
wacom_remote_status_irq() sends information of addition/removal of EKR. We want to allocate one input node per remote, so better having this in a separate worker, not handled in the IRQ directly.

2016-08-05HID: wacom: leds: dynamically allocate LED groupsBenjamin Tissoires3-17/+78
We need to add an action to ensure wacom->led.groups is null when wacom_led_control() gets called after the resources has been freed. This also prevents to send a LED command when there is no support from the device.

wacom_release_shared_data() and wacom_remove_shared_data() are moved up so they can be referenced in wacom_add_shared_data(). There is no point in explicitly setting wacom_wac1->shared->type to 0 in wacom_wireless_work() (plus this would give an oops).

The sysfs group was indeed removed by kobject_put(wacom->remote_dir) in wacom_remove(), but the name of the group was never freed.

Use our own wacom_devm_sysfs_create_group() as there is currently no generic one. It has been requested at least twice [1][2] but has been always rejected. However, in the Wacom case, for the wirelessly connected devices, we need to be able to release the created sysfs files without removing the parent kobject.

Add i2c_hid_shutdown for i2c-hid driver to send suspend cmd & free irq before device shutdown. Some HW design (i.e. Umaro, a chromebook model) is that the power to i2c hid device won't down after device shutdown. Also the i2c-hid driver do not send suspend cmd to the hid i2c device and free its irq before shutdown.So if We touch the touchscreen or some other i2c hid device, the power consumtion will be go up even when the device is in shutdown state. Though the root cause maybe a HW issue. But it seems that it is a good pratice to set power sleep for i2c-hid device before shutdown.
