it is communicating with the right chip.
gtp_read_version is modified to gtp_read_fw_version

Because of a change in the underlying bus driver, the secure touch
layer in the input drivers is now required to control directly the
clocks which are needed during the touch sessions. The clocks which
are associated with the underlying I2C bus are clk_gcc_blsp1_ahb_clk
and clk_gcc_blsp1_qup3_i2c_apps_clk. These clocks are turned on/off
when the secure touch session is started/ended.

During device resume, the touch resume function is called after display's
resume. In this case, the ft5x06's resume function needs to wait for
200ms because of reset requirement. Defer the touch resume to a workqueue
to reduce the total device resume time. For this an optional DT property
is added to enable this on targets that need this feature.

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.
The patch also reorganizes the pinctrl related code in driver.
This patch is propagated from msm-3.18 kernel.
