Input: imx_keypad - make sure keyboard can always wake up system

2019-07-14T06:09:41+00:00

[ Upstream commit ce9a53eb3dbca89e7ad86673d94ab886e9bea704 ]

There are several scenarios that keyboard can NOT wake up system
from suspend, e.g., if a keyboard is depressed between system
device suspend phase and device noirq suspend phase, the keyboard
ISR will be called and both keyboard depress and release interrupts
will be disabled, then keyboard will no longer be able to wake up
system. Another scenario would be, if a keyboard is kept depressed,
and then system goes into suspend, the expected behavior would be
when keyboard is released, system will be waked up, but current
implementation can NOT achieve that, because both depress and release
interrupts are disabled in ISR, and the event check is still in
progress.

To fix these issues, need to make sure keyboard's depress or release
interrupt is enabled after noirq device suspend phase, this patch
moves the suspend/resume callback to noirq suspend/resume phase, and
enable the corresponding interrupt according to current keyboard status.

Input: uinput - add compat ioctl number translation for UI_*_FF_UPLOAD

2019-06-25T03:34:46+00:00

commit 7c7da40da1640ce6814dab1e8031b44e19e5a3f6 upstream.

In the case of compat syscall ioctl numbers for UI_BEGIN_FF_UPLOAD and
UI_END_FF_UPLOAD need to be adjusted before being passed on
uinput_ioctl_handler() since code built with -m32 will be passing
slightly different values. Extend the code already covering
UI_SET_PHYS to cover UI_BEGIN_FF_UPLOAD and UI_END_FF_UPLOAD as well.

Input: synaptics - enable SMBus on ThinkPad E480 and E580

2019-06-25T03:34:46+00:00

commit 9843f3e08e2144724be7148e08d77a195dea257a upstream.

They are capable of using intertouch and it works well with
psmouse.synaptics_intertouch=1, so add them to the list.

Without it, scrolling and gestures are jumpy, three-finger pinch gesture
doesn't work and three- or four-finger swipes sometimes get stuck.

Input: goodix - add GT5663 CTP support

2019-06-15T09:53:03+00:00

[ Upstream commit a5f50c501321249d67611353dde6d68d48c5b959 ]

GT5663 is capacitive touch controller with customized smart
wakeup gestures.

Add support for it by adding compatible and supported chip data.

The chip data on GT5663 is similar to GT1151, like
- config data register has 0x8050 address
- config data register max len is 240
- config data checksum has 16-bit

 "Just a couple of fixups for Synaptics RMI4 driver and allowing
  snvs_pwrkey to be selected on more boards"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: synaptics-rmi4 - write config register values to the right offset

Input: synaptics-rmi4 - write config register values to the right offset

2019-04-27T00:35:32+00:00

Currently any changed config register values don't take effect, as the
function to write them back is called with the wrong register offset.

Input: synaptics-rmi4 - fix possible double free

2019-04-24T16:33:37+00:00

The RMI4 function structure has been released in rmi_register_function
if error occurs. However, it will be released again in the function
rmi_create_function, which may result in a double-free bug.

Input: snvs_pwrkey - make it depend on ARCH_MXC

2019-04-24T16:32:11+00:00

The SNVS power key is not only used on i.MX6SX and i.MX7D, it is also
used by i.MX6UL and NXP's latest ARMv8 based i.MX8M series SOC. So
update the config dependency to use ARCH_MXC, and add the COMPILE_TEST
too.
