HID: Add quirk for incorrect input length on Lenovo Y720

2019-12-13T12:03:48+00:00

Apply it to the Lenovo Y720 gaming laptop I2C peripheral then. This fixes dmesg being flooded with errors visible on un-suspend in Linux Mint 19 Cinnamon. Example of error log: <...> [ 4.326588] i2c_hid i2c-ITE33D1:00: i2c_hid_get_input: incomplete report (2/4) [ 4.326845] i2c_hid i2c-ITE33D1:00: i2c_hid_get_input: incomplete report (2/4) [ 4.327095] i2c_hid i2c-ITE33D1:00: i2c_hid_get_input: incomplete report (2/4) [ 4.327341] i2c_hid i2c-ITE33D1:00: i2c_hid_get_input: incomplete report (2/4) [ 4.327609] i2c_hid i2c-ITE33D1:00: i2c_hid_get_input: incomplete report (2/4) <...> Example of fixed log (debug on) <...> [ 3731.333183] i2c_hid i2c-ITE33D1:00: input: 02 00 [ 3731.333581] i2c_hid i2c-ITE33D1:00: input: 02 00 [ 3731.333842] i2c_hid i2c-ITE33D1:00: input: 02 00 [ 3731.334107] i2c_hid i2c-ITE33D1:00: input: 02 00 [ 3731.334367] i2c_hid i2c-ITE33D1:00: input: 02 00 <...> [jkosina@suse.cz: rebase onto more recent codebase] Signed-off-by: Pavel Balan Signed-off-by: Jiri Kosina

HID: i2c-hid: Reset ALPS touchpads on resume

2019-11-15T15:27:33+00:00

Commit 52cf93e63ee6 ("HID: i2c-hid: Don't reset device upon system resume") fixes many touchpads and touchscreens, however ALPS touchpads start to trigger IRQ storm after system resume. Since it's total silence from ALPS, let's bring the old behavior back to ALPS touchpads.

HID: i2c-hid: fix no irq after reset on raydium 3118

2019-11-15T15:19:03+00:00

On some ThinkPad L390 some raydium 3118 touchscreen devices doesn't response any data after reset, but some does. Add this ID to no irq quirk, then don't wait for any response alike on these touchscreens. All kinds of raydium 3118 devices work fine.

HID: i2c-hid: remove orphaned member sleep_delay

2019-11-15T12:16:05+00:00

This was introduced in commit 00b790ea545b ("HID: i2c-hid: Add a small delay after sleep command for Raydium touchpanel") which has been effectively reverted by commit 67b18dfb8cfc ("HID: i2c-hid: Remove runtime power management"). Signed-off-by: You-Sheng Yang Signed-off-by: Jiri Kosina

HID: i2c-hid: Send power-on command after reset

2019-11-02T19:34:10+00:00

Before commit 67b18dfb8cfc ("HID: i2c-hid: Remove runtime power management"), any i2c-hid touchscreens would typically be runtime-suspended between the driver loading and Xorg or a Wayland compositor opening it, causing it to be resumed again. This means that before this change, we would call i2c_hid_set_power(OFF), i2c_hid_set_power(ON) before the graphical session would start listening to the touchscreen. It turns out that at least some SIS touchscreens, such as the one found on the Asus T100HA, need a power-on command after reset, otherwise they will not send any events.

HID: i2c-hid: add Trekstor Primebook C11B to descriptor override

2019-10-18T13:49:19+00:00

The Primebook C11B uses the SIPODEV SP1064 touchpad. There are 2 versions of this 2-in-1 and the touchpad in the older version does not supply descriptors, so it has to be added to the override list. Cc: stable@vger.kernel.org Signed-off-by: Hans de Goede Signed-off-by: Benjamin Tissoires

HID: i2c-hid: Remove runtime power management

2019-10-18T13:29:56+00:00

Runtime power management in i2c-hid brings lots of issues, such as: - When transitioning from display manager to desktop session, i2c-hid was closed and opened, so the device was set to SLEEP and ON in a short period. Vendors confirmed that their devices can't handle fast ON/SLEEP command because Windows doesn't have this behavior. - When rebooting, i2c-hid was closed, and the driver core put the device back to full power before shutdown. This behavior also triggers a quick SLEEP and ON commands that some devices can't handle, renders an unusable touchpad after reboot. - Most importantly, my power meter reports little to none energy saving when i2c-hid is runtime suspended. So let's remove runtime power management since there is no actual benefit. Signed-off-by: Kai-Heng Feng Acked-by: Hans de Goede Signed-off-by: Benjamin Tissoires

HID: i2c-hid: modify quirks for weida's devices

2019-09-04T12:30:35+00:00

This 'SET_PWR_WAKEUP_DEV' quirk only works for weida's devices with pid 0xC300 & 0xC301. Some weida's devices with other pids also need this quirk now. Use 'HID_ANY_ID' instead of 0xC300 to make all of weida's devices can be fixed on the power on issue. This modification should be safe since devices without power on issue will send the power on command only once. Signed-off-by: HungNien Chen Signed-off-by: Jiri Kosina
