Input: elantech - enable 3rd button support on Fujitsu CELSIUS H780

2019-02-20T09:20:53Z

commit e8b22d0a329f0fb5c7ef95406872d268f01ee3b1 upstream. Like Fujitsu CELSIUS H760, the H780 also has a three-button Elantech touchpad, but the driver needs to be told so to enable the middle touchpad button. The elantech_dmi_force_crc_enabled quirk was not necessary with the H780. Also document the fw_version and caps values detected for both H760 and H780 models.

According to Elan: "Acer Aspire F5-573G is MS Precision touchpad which should use hid multitouch driver. ELAN0501 should not be added in elan_i2c."

Input: xpad - add support for SteelSeries Stratus Duo

2019-01-31T07:13:45Z

commit fe2bfd0d40c935763812973ce15f5764f1c12833 upstream. Add support for the SteelSeries Stratus Duo, a wireless Xbox 360 controller. The Stratus Duo ships with a USB dongle to enable wireless connectivity, but it can also function as a wired controller by connecting it directly to a PC via USB, hence the need for two USD PIDs. 0x1430 is the dongle, and 0x1431 is the controller.

2019-01-13T09:01:01Z

[ Upstream commit 7a71712293ba303aad928f580b89addb0be2892e ] dmesg reports that "Your touchpad (PNP: SYN3052 SYN0100 SYN0002 PNP0f13) says it can support a different bus." I've tested the offered psmouse.synaptics_intertouch=1 with 4.18.x and 4.19.x and it seems to work well. No problems seen with suspend/resume. Also, it appears that RMI/SMBus mode is actually required for 3-4 finger multitouch gestures to work -- otherwise they are not reported at all.

Input: omap-keypad - fix idle configuration to not block SoC idle states

2019-01-13T09:00:57Z

[ Upstream commit e2ca26ec4f01486661b55b03597c13e2b9c18b73 ] With PM enabled, I noticed that pressing a key on the droid4 keyboard will block deeper idle states for the SoC. Let's fix this by using IRQF_ONESHOT and stop constantly toggling the device OMAP4_KBD_IRQENABLE register as suggested by Dmitry Torokhov . From the hardware point of view, looks like we need to manage the registers for OMAP4_KBD_IRQENABLE and OMAP4_KBD_WAKEUPENABLE together to avoid blocking deeper SoC idle states. And with toggling of OMAP4_KBD_IRQENABLE register now gone with IRQF_ONESHOT, also the SoC idle state problem is gone during runtime. We still also need to clear OMAP4_KBD_WAKEUPENABLE in omap4_keypad_close() though to pair it with omap4_keypad_open() to prevent blocking deeper SoC idle states after rmmod omap4-keypad.
