2021-02-16Input: elants_i2c - detect enum overflowJosh Poimboeuf1-2/+1
If an enum value were to get added without updating this switch statement, the unreachable() annotation would trigger undefined behavior, causing execution to fall through the end of the function, into the next one. Make the error handling more robust for an unexpected enum value, by doing BUG() instead of unreachable().

2021-01-24Input: iqs5xx - allow more time for ATI to completeJeff LaBundy1-6/+5
After the device is initialized, it runs ATI (calibration) during which it cannot readily respond to I2C communication. To keep the open and close callbacks from writing to the device too soon, the driver waits 100 ms before returning from probe. The vendor reports that ATI may actually take up to 250 ms to run (including margin), so increase the delay accordingly. Update the comments to clarify the reason for the delay as well.

2021-01-24Input: iqs5xx - eliminate unnecessary register readJeff LaBundy1-19/+12
Instead of relying on firmware to enable important register fields and performing read-modify-write operations to additionally enable the fields the driver cares about, it's much simpler just to write all of the pertinent fields explicitly. This avoids an unnecessary register read operation at start-up and makes way for the iqs5xx_read_byte() helper to be dropped.

2021-01-24Input: iqs5xx - simplify axis setup logicJeff LaBundy1-79/+21
The present implementation manipulates axis swap and inversion fields in the device to more or less duplicate what touchscreen_report_pos() does. The resulting logic is convoluted and difficult to follow. Instead report the maximum X and Y coordinates in earnest as they are read from the device, then let touchscreen_parse_properties() fix the axes up as necessary. Finally, use touchscreen_report_pos() to report the transformed coordinates. Last but not least, the maximum X and Y coordinates are not functions of the number of rows/columns that comprise the touch surface. Either coordinate is simply limited to 1 below what is reported for absolute X or Y coordinates when no fingers are present (0xFFFF).

2021-01-24Input: iqs5xx - re-initialize device upon warm resetJeff LaBundy1-11/+41
The device may be inadvertently reset during runtime in the event of ESD strike, etc. To protect against this case, acknowledge the SHOW_RESET interrupt and re-initialize the device. To facilitate this change, expand the range of registers that are read in the interrupt handler to include the system status fields. Also, update the unrelated (but nearby) SUSPEND register field to use the BIT() macro. The remaining register fields are cleaned up in another patch.

2021-01-24Input: iqs5xx - accommodate bootloader latencyJeff LaBundy1-2/+7
The bootloader NAK's all I2C communication after the first 64-byte bulk write if the bus frequency is equal to 400 kHz. This prevents the platform from pushing updated firmware to the device. The vendor's USB bootloader programming dongle appears to insert a delay between the "open" command and the first 64-byte bulk write. Adding a similar delay to the driver seems to eliminate the issue. Furthermore, the dongle does not access the bootloader immediately after powering up the device. Follow suit by adding a delay before the "open" command to avoid wasted retries at 400 kHz.

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().

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.

2021-01-10Input: 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]>.

2020-12-10Input: synaptics-rmi4 - use new structure for SPI transfer delaysSergiu Cuciurean1-2/+4
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).
