Linus Torvalds 5b4746a031 Merge tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk fixes from Stephen Boyd:
 "Mostly driver fixes, but there's a core framework fix in here too:

   - Revert the commits that introduce clk management for the SP clk on
     MMP2 SoCs (used for OLPC). Turns out it wasn't a good idea and
     there isn't any need to manage this clk, it just causes more
     headaches.

   - A performance regression that went unnoticed for many years where
     we would traverse the entire clk tree looking for a clk by name
     when we already have the pointer to said clk that we're looking for

   - A parent linkage fix for the qcom SDM845 clk driver

   - An i.MX clk driver rate miscalculation fix where order of
     operations were messed up

   - One error handling fix from the static checkers"

Lubomir Rintel 0113613faf Revert "Input: olpc_apsp - enable the SP clock"
Turns out this is not such a great idea. Once the SP clock is disabled,
it's not sufficient to just enable in order to bring the SP core back up.

It seems that the kernel has no business managing this clock. Just let
the firmware keep it enabled.

This reverts commit ed22cee91a.

Lubomir Rintel ec87da107d Input: olpc_apsp - assign priv->dev earlier
The dev field needs to be set when serio_register_port() is called,
because the open callback may use it (in the error handling path).

Dmitry Torokhov d77651a227 Input: uinput - fix undefined behavior in uinput_validate_absinfo()
An integer overflow may arise in uinput_validate_absinfo() if "max - min"
can't be represented by an "int". We should check for overflow before
trying to use the result.

Anders Roxell 4add635b4e Input: raspberrypi-ts - fix link error
Fix link error when TOUCHSCREEN_RASPBERRYPI_FW is enabled as a module and
the dependent module is built-in.  The 'depends on RASPBERRYPI_FIRMWARE' by
itself prevents the touchscreen driver from being built-in when the
firmware is configured as a module.  However, the '|| COMPILE_TEST' still
allows it unless we explicitly prevent that configuration with
'|| (RASPBERRYPI_FIRMWARE=n && COMPILE_TEST)'.

ld: drivers/input/touchscreen/raspberrypi-ts.o: in function `rpi_ts_probe':
raspberrypi-ts.c:(.text+0x3a8): undefined reference to `rpi_firmware_get'

Rework so that TOUCHSCREEN_RASPBERRYPI_FW depends on

Tom Panfil fe2bfd0d40 Input: xpad - add support for SteelSeries Stratus Duo
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.

Mantas Mikulėnas 7a71712293 Input: synaptics - enable SMBus for HP EliteBook 840 G4
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.

Information from dmesg in both modes:

The current implementation of elan_i2c is known to not support those
2 laptops.

A proper fix is to tweak both elantech and elan_i2c to transmit the
correct information from PS/2, which would make a bad candidate for
stable.

So to give us some time for fixing the root of the problem, disable
elan_i2c for the devices we know are not behaving properly.
