commit 4097461897df91041382ff6fcd2bfa7ee6b2448c upstream.
As explained in 1407814240-4275-1-git-send-email-decui@microsoft.com we
have a hard load dependency between i8042 and atkbd which prevents
keyboard from working on Gen2 Hyper-V VMs.
> hyperv_keyboard invokes serio_interrupt(), which needs a valid serio
> driver like atkbd.c. atkbd.c depends on libps2.c because it invokes
> ps2_command(). libps2.c depends on i8042.c because it invokes
> i8042_check_port_owner(). As a result, hyperv_keyboard actually
> depends on i8042.c.
>
> For a Generation 2 Hyper-V VM (meaning no i8042 device emulated), if a
> Linux VM (like Arch Linux) happens to configure CONFIG_SERIO_I8042=m
> rather than =y, atkbd.ko can't load because i8042.ko can't load(due to
> no i8042 device emulated) and finally hyperv_keyboard can't work and
> the user can't input: https://bugs.archlinux.org/task/39820
> (Ubuntu/RHEL/SUSE aren't affected since they use CONFIG_SERIO_I8042=y)
To break the dependency we move away from using i8042_check_port_owner()
and instead allow serio port owner specify a mutex that clients should use
to serialize PS/2 command stream.

Fixed below irq flag issues of Focaltech CTP:
Focaltech CTP firmware generates edge interrupt to MSM, but the
interrupt type in DTSI is level, which will cause CTP interrupt
cannot wake up MSM when system is in deep sleep. Fix this by
setting edge irq flag in DTSI.
For GPIO irq, the irq flag should be specified in "interrupts"
node. Msm_gpio module will only use the lower 8-bit of
"interrupts" node and discards the upper bits. If we specify
0x2002 in "interrupts" node, the upper bits(0x2000) is not used
by msm_gpio, only lower bits(0x2) is used, that means only
lower bits(0x2) should be set in "interrupts" node.
"focaltech,irq-gpio" node is used to specify gpio property,
rather than irq flag. Remove the irq flag setting in this node.
In driver code, specify only "IRQF_ONESHOT". The irq trigger type
is specified by DTSI "interrupts" node. See above.

devm_pinctrl_get() does not release the ownership of mux function
of pins in the associated pin-group whenever a failure occurs in
driver probe routine. i.e struct pin_desc's mux_owner field is
still marked as being in use after a failure occurs in probe.
As a result of this, if another driver tries to acquire the
ownership of same pin, it gets an error while applying that
setting. To fix this, explicitly release the mux function
ownership of the the pin, by adding a new pin-group in pinctrl
DT and a new pinctrl state in touch device's DT node. This new
pin-group does not have a function setting (qcom,pin-func property).
This new state is explicitly activated during a probe failure
and driver remove routine to release the mux function ownership.
