Prior to this patch, the sensing configuration data was not parsed correctly, breaking detection of max_tch. The vendor driver includes this field. This change informs the driver about the correct maximum number of simultaneous touch inputs. Tested on a Pine64 PineNote with a modified touch screen controller firmware. Signed-off-by:

A lot of modern Clevo barebones have touchpad and/or keyboard issues after suspend fixable with nomux + reset + noloop + nopnp. Luckily, none of them have an external PS/2 port so this can safely be set for all of them. I'm not entirely sure if every device listed really needs all four quirks, but after testing and production use, no negative effects could be observed when setting all four. Setting SERIO_QUIRK_NOMUX or SERIO_QUIRK_RESET_ALWAYS on the Clevo N150CU and the Clevo NHxxRZQ makes the keyboard very laggy for ~5 seconds after boot and sometimes also after resume. However both are required for the keyboard to not fail completely sometimes after boot or resume. Signed-off-by:

The AlpsPS/2 code previously relied on the assumption that `char` is a signed type, which was true on x86 platforms (the only place where this driver is used) before kernel 6.2. However, on 6.2 and later, this assumption is broken due to the introduction of -funsigned-char as a new global compiler flag. Fix this by explicitly specifying the signedness of `char` when sign extending the values received from the device. Fixes: f3f33c67 ("Input: alps - Rushmore and v7 resolution support") Signed-off-by:

The Android Lenovo Yoga Book X90F / X90L uses the same goodix touchscreen with 9 bytes touch reports for its touch keyboard as the already supported Windows Lenovo Yoga Book X91F/L, add a DMI match for this to the nine_bytes_report DMI table. When the quirk for the X91F/L was initially added it was written to also apply to the X90F/L but this does not work because the Android version of the Yoga Book uses completely different DMI strings. Also adjust the X91F/L quirk to reflect that it only applies to the X91F/L models. Signed-off-by:

Following a recent refactor of the driver to properly drop unused device nodes, the driver expects trackpad channel touch thresholds and ATI base values to be specified under single trackpad channel child nodes.

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 never calls fwnode_handle_put(); this patch adds the missing calls. Because fwnode_handle_put() does not take a const *fwnode_handle, the const qualifier is removed across all corresponding *fwnode_handle instances. As part of this change, trackpad channel touch thresholds and ATI base values are now specified under single trackpad channel child nodes. This enhancement moves both properties to scalar values as opposed to arrays, making their types consistent across bindings. Fixes: f1d2809d ("Input: Add support for Azoteq IQS626A") Signed-off-by:

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:

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). 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.
