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. Change-Id: If5abca579e264cc7799310628c4e379ac4368e7e Signed-off-by: Abinaya P <abinayap@codeaurora.org>

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. Change-Id: I4cd8596fb4538b701317f01a6cafaa771041ffdd Signed-off-by: Mao Li <maol@codeaurora.org>

Touch resume function will take about >200ms. Defer the touch resume function to a workqueue to reduce the total device resume time. An optional DT property is added to enable this on targets that need this feature. This change has been merged. Now, touch driver was updated to V2.6, so, merge this change to V2.6 driver.

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.

The pinctrl must be configure first before the gpio configuration. Select the pinctrl sleep state and after that in gpio configuration part free both IRQ and reset gpio, and also set direction of reset gpio to be input. If the gpio and pinctrl is not in proper state the touch controller will not switch to the deep sleep state and it will start consume current during the device suspend state. To prevent this leakage current issue, pinctrl and gpio must be configured properly. This patch is propagated from msm-3.18 kernel. 'commit 494eae39f2a4 ("input: ft5x06_ts: pinctrl and gpio config in suspend/resume path")' Also cleared checkpatch errors on msm-3.18 kernel.

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.
