Looks like the Bios of the Lenovo Legion Y7000 is using ELAN061B when the actual device is supposed to be used with hid-multitouch. Remove it from the list of the supported device, hoping that no one will complain about the loss in functionality.

We need to reset input device's timestamp on input_sync(), otherwise drivers not using input_set_timestamp() will end up with a stale timestamp after their clients consume first input event. Fixes: 3b51c44b ("Input: allow drivers specify timestamp for input events") Reported-by:

If the touchscreen is configured as wakeup source we should not be cutting off power to it. Also, now that the driver relies on I2C client to supply IRQ, we do not need to explicitly enable and disable IRQ for wakeup: if device is created as wakeup source, I2C core will mark interrupt as wakeup one.

Instead of trying to map INT GPIO to interrupt, let's use one supplied by I2C client. If there is none - bail. This will also allow us to treat INT GPIO as optional, as per the binding. Tested-by:

There are no current users of the platform data in the tree, and any new users should either use device tree, or static device properties to describe the device. This change drop the platform data definition and handling and moves the driver over to generic device properties API. We also drop support for the external clock. If it is needed we will have to extend the bindings to supply the clock reference and handle it properly in the driver. Also, wakeup setting should be coming from I2C client. Tested-by:

"bu21013_data" and "struct bu21013_ts_data" are a tad long, let's call them "ts" and "struct bu21013_ts". Also rename retval to error in bu21013_init_chip() and adjust formatting; i2c_smbus_write_byte_data() returns negative on error and 0 on success, so we simply test if whether erro is 0 or not.

This driver can use GPIO descriptors rather than GPIO numbers without any problems, convert it. Name the field variables after the actual pins on the chip rather than the "reset" and "touch" names from the devicetree bindings that are vaguely inaccurate. No in-tree users pass GPIO numbers in platform data so drop this. Descriptor tables can be used to get these GPIOs from a board file if need be. Signed-off-by:

We don't know when the device will be added with device_add() in serio_add_port() because serio_add_port() is called from a workqueue that this driver schedules by calling serio_register_port(). The best we can know is that the device will definitely not have been added yet when the start callback is called on the serio device. While it hasn't been shown to be a problem, proactively move the wakeup enabling calls to the start hook so that we don't race with the workqueue calling device_add(). This will avoid racy situations where code tries to add wakeup sysfs attributes for this device from dpm_sysfs_add() but the path in device_set_wakeup_capable() has already done so. Signed-off-by:

Recently we had a building error if we enable the MOUSE_PS2_ALPS while disable the MOUSE_PS2_TRACKPOINT, and was fixed by 49e6979e ("Input: psmouse - fix build error of multiple definition"). We could improve that fix by dropping all unneeded functions and CONFIG_MOUSE_ guards from the header, it is safe to do that since those functions are not directly called by psmouse-base.c anymore.

Separating "normal" and "polled" input devices was a mistake, as often we want to allow the very same device work on both interrupt-driven and polled mode, depending on the board on which the device is used. This introduces new APIs: - input_setup_polling - input_set_poll_interval - input_set_min_poll_interval - input_set_max_poll_interval These new APIs allow switching an input device into polled mode with sysfs attributes matching drivers using input_polled_dev APIs that will be eventually removed.

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).
