Prior to this patch, the bitmask ends up being 0x3, as opposed to 0x1 which likely was the intention. The erroneous bit results in the driver reporting 2 different button activations in designs with 2 or more buttons. To detect which button has been pressed, cyttsp5_btn_attention() uses a for loop to iterate through the input buffer, while shifting and applying a bitmask to determine the state for each button. Unfortunately, when the bitmask is 0x3 and there are multiple buttons, this procedure falls apart. Consider a design with 3 buttons. Pressing the third button will result in a call to cyttsp5_btn_attention() with the input buffer containing 0x4 (binary 0100). In the first iteration of the for loop cur_btn_state will be: (0x4 >> 0 * 1) & 0x3 = 0x4 & 0x3 = 0x0 This is correct. However, in the next iteration this happens: (0x4 >> 1 * 1) & 0x3 = 0x2 & 0x3 = 0x2 Which means that a key event for key 1 is generated, even though it's not really active. In the third iteration, the loop detects the button that was actually pressed: (0x4 >> 2 * 1) & 0x3 = 0x1 & 0x3 = 0x1 This key event is the only one that should have been detected, but it is accompanied by the preceding key. Ensuring the applied mask is 0x1 solves this problem. Signed-off-by:

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 guards only apply to suspend and resume, #ifdef CONFIG_PM_SLEEP would have been a tighter protection. As pm_sleep_ptr() lets the compiler see the protected ops structure and callbacks but also lets the compiler remove it as unused code if !CONFIG_PM_SLEEP this allows the #ifdef guards to be removed, slightly simplifying the resulting code. -- It seems likely that DEFINE_SIMPLE_DEV_PM_OPS() would work here but I'd prefer not to make that change unless someone can confirm that the extra callbacks registered will have no unwanted side effects in this driver.

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. Use that in the input core to simplify the code a little. Note pm_sleep_ptr() has not been applied to each callback in the ops structure because the pm_sleep_ptr() at the usage site is sufficient.

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). As such rather than just moving these to SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() take the opportunity to unify the struct dev_pm_ops and use the new EXPORT_SIMPLE_DEV_PM_OPS() macro so that we can drop the unused suspend and resume callbacks as well as the structure if !CONFIG_PM_SLEEP without needing to mark the callbacks __maybe_unused.

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.
