2021-01-24Input: iqs5xx - preserve bootloader errorsJeff LaBundy1-1/+5
After user space writes the fw_file attribute to push new firmware to the device, the driver calls iqs5xx_dev_init() to re-initialize the device with the updated firmware or recover the device in case the update failed. In the case of the latter, however, iqs5xx_fw_file_write() returns zero (success) so long as iqs5xx_dev_init() does not fail, and any error encountered during the update process is lost. Solve this by saving the error before calling iqs5xx_dev_init().

Copyrights are generally followed by the name of a person or a company (i.e. the copyright holder) but that was not done here. Fix this by squashing the 'copyright' and 'author' lines. Also, trim some leading whitespace ahead of the parameters for the fw_file_store() function and re-align them for readability.

Add ELAN KTF3624 touchscreen support to the elants_i2c driver. The eKTF3624 TS is found on a series of ASUS Transformer tablet devices, Nexus 7 tablet and etc. The firmware interface of eKTF3624 is nearly identical to eKTH3500, which is already supported by the driver. The minor differences of the firmware interface are now handled by the driver. The eKTF3624 support was tested on ASUS Transformer TF700T, TF300T and Nexus 7 tablets.

2021-01-20Input: ads7846 - convert to one messageOleksij Rempel1-183/+193
Convert multiple full duplex transfers in to a single transfer to reduce CPU load. Current driver version support following filtering modes: - ads7846_no_filter() - not filtered - ads7846_debounce_filter() - driver specific debounce filter - pdata->filter - platform specific debounce filter (do any platform provides such filter?) Without filter this HW is not really usable, since the physic of resistive touchscreen can provide some bounce effects. With driver internal filter, we have constant amount of retries + debounce retries if some anomaly was detected. High amount of tiny SPI transfers is the primer reason of high CPU load and interrupt frequency. This patch create one SPI transfer with all fields and not optional retires. If bounce anomaly was detected, we will make more transfer if needed. Without this patch, we will get about 10% CPU load on iMX6S on pen-down event. For example by holding stylus on the screen. With this patch, depending in the amount of retries, the CPU load will be 1% with "ti,debounce-rep = <3>". One buffer transfer allows us to use PIO FIFO or DMA engine, depending on the platform.

2021-01-20tty: convert tty_ldisc_ops 'read()' function to take a kernel pointerLinus Torvalds1-1/+3
The tty line discipline .read() function was passed the final user pointer destination as an argument, which doesn't match the 'write()' function, and makes it very inconvenient to do a splice method for ttys. This is a conversion to use a kernel buffer instead. NOTE! It does this by passing the tty line discipline ->read() function an additional "cookie" to fill in, and an offset into the cookie data. The line discipline can fill in the cookie data with its own private information, and then the reader will repeat the read until either the cookie is cleared or it runs out of data. The only real user of this is N_HDLC, which can use this to handle big packets, even if the kernel buffer is smaller than the whole packet.

2021-01-10Input: omap4-keypad - implement errata check for lost key-up eventsTony Lindgren1-0/+30
We are still missing handling for errata i689 related issues for the case where we never see a key up interrupt for the last pressed key. To fix the issue, we must scan the key state again after the keyboard controller has idled to check if a key up event was missed. This is described in the omap4 silicon errata documentation for Errata ID i689 "1.32 Keyboard Key Up Event Can Be Missed": "When a key is released for a time shorter than the debounce time, in-between 2 key press (KP1 and KP2), the keyboard state machine will go to idle mode and will never detect the key release (after KP1, and also after KP2), and thus will never generate a new IRQ indicating the key release." We can use PM runtime autosuspend features to check the keyboard state after it enters idle.

2021-01-10Input: omap4-keypad - scan keys in two phases and simplify with bitmaskTony Lindgren1-28/+45
Because of errata i689 the keyboard can idle with state where no key up interrupts are seen until after the next key press. This means we need to first check for any lost key up events before scanning for new down events. For example, rapidly pressing shift-shift-j can sometimes produce a J instead of j. Let's fix the issue by scanning the keyboard in two phases. First we scan for any key up events that we may have missed, and then we scan for key down events. Let's also simplify things with for_each_set_bit() as suggested by Dmitry Torokhov <[email protected]>.

2021-01-01Input: st1232 - wait until device is ready before reading resolutionGeert Uytterhoeven1-0/+35
According to the st1232 datasheet, the host has to wait for the device to change into Normal state before accessing registers other than the Status Register. If the reset GPIO is wired, the device is powered on during driver probe, just before reading the resolution. However, the latter may happen before the device is ready, leading to a probe failure: st1232-ts 1-0055: Failed to read resolution: -6 Fix this by waiting until the device is ready, by trying to read the Status Register until it indicates so, or until timeout. On Armadillo 800 EVA, typically the first read fails with an I2C transfer error, while the second read indicates the device is ready.

2020-12-11Input: cm109 - do not stomp on control URBDmitry Torokhov1-2/+5
We need to make sure we are not stomping on the control URB that was issued when opening the device when attempting to toggle buzzer. To do that we need to mark it as pending in cm109_open().

2020-12-11Input: adp5589-keys - do not explicitly control IRQ for wakeupDmitry Torokhov1-18/+9
If device is set up as a wakeup source, I2C core configures the interrupt line as wake IRQ and PM core automatically configures it for waking up the system on system suspend transition, so we do not have to explicitly call enable_irq_wake() and disable_irq_wake() in suspend/resume.

2020-12-11Input: adp5589-keys - do not unconditionally configure as wakeup sourceDmitry Torokhov1-2/+0
We should not be configuring the controller as a wakeup source in the driver, but rather rely on I2C core to mark it as such by either instantiating as I2C_CLIENT_WAKEUP or specifying "wakeup-source" device property.

2020-12-11Input: elantech - fix protocol errors for some trackpoints in SMBus modejingle.wu2-2/+101
There are some version of Elan trackpads that send incorrect data when in SMbus mode, unless they are switched to use 0x5f reports instead of standard 0x5e. This patch implements querying device to retrieve chips identifying data, and switching it, when needed to the alternative report.

2020-12-10Input: applespi - use new structure for SPI transfer delaysSergiu Cuciurean1-4/+8
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).
