Controllers that report pressure (e.g. ADS7846) use 5 commands and the correct sequence is READ_X, READ_Y, READ_Z1, READ_Z2, PWRDOWN. Controllers that don't report pressure (e.g. ADS7845/ADS7843) use only 3 commands and the correct sequence should be READ_X, READ_Y, PWRDOWN.

As the new pm_sleep_ptr() macro lets the compiler see the code, but then remove it if !CONFIG_PM_SLEEP it can be used to avoid the need for #ifdef guards.

The I2C and SPI PM callbacks were identical (though wrapped in some bouncing out to the bus specific container of the struct device and then back again to get the drvdata).

After initial start-up, the driver triggers ATI (calibration) with the newly loaded register configuration in place. Next, the driver polls a register field to ensure ATI completed in a timely fashion and that the device is ready to sense. However, communicating with the device over I2C while ATI is under- way may induce noise in the device and cause ATI to fail. As such, the vendor recommends not to poll the device during ATI. To solve this problem, let the device naturally signal to the host that ATI is complete by way of an interrupt. A completion prevents the device from successfully probing until this happens. As an added benefit, initial switch states are now reported in the interrupt handler at the same time ATI status is checked. As such, duplicate code that reports initial switch states has been removed from iqs269_input_init(). The former logic that scaled ATI timeout and filter settling delay is not carried forward with the new implementation, as it produces overly conservative delays at the lower clock rate. Rather, a single timeout that covers both clock rates is used. The filter settling delay does not happen to be necessary and has been removed as well.

Polling the device while it transitions from automatic to manual power mode switching may keep the device from actually finishing the transition. The process appears to time out depending on the polling rate and the device's core clock frequency. This is ultimately unnecessary in the first place; instead it is sufficient to write the desired mode during initialization, then disable automatic switching at suspend. This eliminates the need to ensure the device is prepared for a manual change and removes the 'suspend_mode' variable. Similarly, polling the device while it transitions from one mode to another under manual control may time out as well. This added step does not appear to be necessary either, so drop it.

Unless it is being done as part of servicing a soft reset interrupt, configuring channels on-the-fly (as is the case when writing to the ati_trigger attribute) may cause GPIO3 (which reflects the state of touch for a selected channel) to be inadvertently asserted. To solve this problem, follow the vendor's recommendation and write all channel configuration as well as the REDO_ATI register field as part of a single block write. This ensures the device has been told to re-calibrate itself following an I2C stop condition, after which sensing resumes and GPIO3 may be asserted.

The time the device takes to deassert its RDY output following an I2C stop condition scales with the core clock frequency. To prevent level-triggered interrupts from being reasserted after the interrupt handler returns, increase the time before returning to account for the worst-case delay (~140 us) plus margin.

Each call to device/fwnode_get_named_child_node() must be matched with a call to fwnode_handle_put() once the corresponding node is no longer in use. This ensures a reference count remains balanced in the case of dynamic device tree support. Currently, the driver does not call fwnode_handle_put() on nested event nodes. This patch solves this problem by adding the missing instances of fwnode_handle_put(). As part of this change, the logic which parses each channel's key code is gently refactored in order to reduce the number of places from which fwnode_handle_put() is called.

This driver never used the older SIMPLE_DEV_PM_OPS() but instead just set two of the callbacks directly. Skip that deprecated macro and go straight to the new form that avoids the need for guarding or marking callbacks __maybe_unused. -- It is possible there is some subtle reason why only two of the callbacks normally set by SIMPLE_DEV_PM_OPS() are set. As such, this one needs some closer reading than many of the others. Signed-off-by:
