Input: raydium_i2c_ts - fix error codes in raydium_i2c_boot_trigger()

2020-03-06T22:37:56Z

These functions are supposed to return negative error codes but instead it returns true on failure and false on success. The error codes are eventually propagated back to user space.

Input: ili210x - fix return value of is_visible function

2020-02-10T18:00:01Z

The is_visible function expects the permissions associated with an attribute of the sysfs group or 0 if an attribute is not visible. Change the code to return the attribute permissions when the attribute should be visible which resolves the warning: Attribute calibrate: Invalid permissions 01 Fixes: cc12ba1872c6 ("Input: ili210x - optionally show calibrate sysfs attribute") Signed-off-by: Luca Weiss Reviewed-by: Sven Van Asbroeck Link: https://lore.kernel.org/r/20200209145628.649409-1-luca@z3ntu.xyz Signed-off-by: Dmitry Torokhov

Input: ads7846 - use new `delay` structure for SPI transfer delays

2020-01-21T04:45:25Z

In a recent change to the SPI subsystem [1], a new `delay` struct was added to replace the `delay_usecs`. This change replaces the current `delay_usecs` with `delay` for this driver. The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure that both `delay_usecs` & `delay` are used (in this order to preserve backwards compatibility).

Sync up with mainline to get SPI "delay" API changes.

Input: edt-ft5x06 - use pm core to enable/disable the wake irq

2020-01-10T22:45:36Z

We do not have to handle the wake-irq within the driver because the pm core can handle this for us. The only use case for the suspend/resume callbacks was to handle the wake-irq so we can remove the callbacks. Signed-off-by: Marco Felsch Signed-off-by: Dmitry Torokhov

Input: edt-ft5x06 - make wakeup-source switchable

2020-01-10T22:45:35Z

Since day one the touch controller acts as wakeup-source. This seems to be wrong since the device supports deep-sleep mechanism [1] which requires a reset to leave it. Also some designs won't use the touchscreen as wakeup-source. According discussion [2] we decided to break backward compatibility and go the common way by using the 'wakeup-source' device-property.

Input: edt-ft5x06 - alphabetical include reorder

It seems that the include order is historical increased and no one takes care of it. Fix this to align it with the common rule to be in a alphabetical order. Signed-off-by: Marco Felsch Tested-by: Andy Shevchenko Reviewed-by: Andy Shevchenko Signed-off-by: Dmitry Torokhov

Input: edt-ft5x06 - work around first register access error

2020-01-10T22:45:33Z

The EP0700MLP1 returns bogus data on the first register read access (reading the threshold parameter from register 0x00): edt_ft5x06 2-0038: crc error: 0xfc expected, got 0x40 It ignores writes until then. This patch adds a dummy read after which the number of sensors and parameter read/writes work correctly.
