2018-10-11HID: wacom: Work around HID descriptor bug in DTK-2451 and DTH-2452Jason Gerecke
The DTK-2451 and DTH-2452 have a buggy HID descriptor which incorrectly contains a Cintiq-like report, complete with pen tilt, rotation, twist, serial number, etc. The hardware doesn't actually support this data but our driver duitifully sets up the device as though it does. To ensure userspace has a correct view of devices without updated firmware, we clean up this incorrect data in wacom_setup_device_quirks. We're also careful to clear the WACOM_QUIRK_TOOLSERIAL flag since its presence causes the driver to wait for serial number information (via wacom_wac_pen_serial_enforce) that never comes, resulting in the pen being non-responsive.

2018-09-24HID: i2c-hid: Remove RESEND_REPORT_DESCR quirk and its handlingHans de Goede
Commit 52cf93e63ee6 ("HID: i2c-hid: Don't reset device upon system resume") removes the need for the RESEND_REPORT_DESCR quirk for Raydium devices, but kept it for the SIS device id 10FB touchscreens, as the author of that commit could not determine if the quirk is still necessary there. I've tested suspend/resume on a Toshiba Click Mini L9W-B which is the device for which this quirk was added in the first place and with the "Don't reset device upon system resume" fix the quirk is no longer necessary, so this commit removes it. Note even better I also had some other devices with SIS touchscreens which suspend/resume issues, where the RESEND_REPORT_DESCR quirk did not help. I've also tested these devices with the "Don't reset device upon system resume" fix and I'm happy to report that that fix also fixes touchscreen resume on the following devices: Asus T100HA Asus T200TA Peaq C1010 Cc: Kai-Heng Feng <kai.heng.feng@canonical.com> Acked-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2018-09-14HID: i2c-hid: disable runtime PM operations on hantick touchpadAnisse Astier
This hantick HTIX5288 touchpad can quickly fall in a wrong state if there are too many open/close operations. This will either make it stop reporting any input, or will shift all the input reads by a few bytes, making it impossible to decode. Here, we never release the probed touchpad runtime pm while the driver is loaded, which should disable all runtime pm suspend/resumes. This fast repetition of sleep/wakeup is also more likely to happen when using runtime PM, which is why the quirk is done there, and not for all power downs, which would include suspend or module removal.

Raydium touchscreen triggers interrupt storm after system-wide suspend: [ 179.085033] i2c_hid i2c-CUST0000:00: i2c_hid_get_input: incomplete report (58/65535) According to Raydium, Windows driver does not reset the device after system resume. The HID over I2C spec does specify a reset should be used at intialization, but it doesn't specify if reset is required for system suspend. Tested this patch on other i2c-hid touchpanels I have and those touchpanels do work after S3 without doing reset. If any regression happens to other touchpanel vendors, we can use quirk for Raydium devices. There's still one device uses I2C_HID_QUIRK_RESEND_REPORT_DESCR so keep it there.
