The bt541 seems to support touch keys, but the support was not added because that functionality is not being utilized by the touchscreen used for testing.

2020-09-13Input: raydium_i2c_ts - use single i2c_transfer transaction when using ↵Furquan Shaikh1-73/+58
RM_CMD_BANK_SWITCH On an AMD chromebook, where the same I2C bus is shared by both Raydium touchscreen and a trackpad device, it is observed that interleaving of I2C messages when `raydium_i2c_read_message()` is called leads to the Raydium touch IC reporting incorrect information. This is the sequence that was observed to result in the above issue: * I2C write to Raydium device for RM_CMD_BANK_SWITCH * I2C write to trackpad device * I2C read from trackpad device * I2C write to Raydium device for setting address * I2C read from Raydium device >>>> This provides incorrect information This change adds a new helper function `raydium_i2c_xfer()` that performs I2C transactions to the Raydium device. It uses the register address to decide if RM_CMD_BANK_SWITCH header needs to be sent to the device (i.e. if register address is greater than 255, then bank switch header is sent before the rest of the transaction). Additionally, it ensures that all the I2C operations performed as part of `raydium_i2c_xfer()` are done as a single i2c_transfer. This guarantees that no other transactions are initiated to any other device on the same bus in between. Additionally, `raydium_i2c_{send|read}*` functions are refactored to use this new helper function. Verified with the patch across multiple reboots (>100) that the information reported by the Raydium touchscreen device during probe is correct.

2020-09-13Input: soc_button_array - work around DSDTs which modify the irqflagsHans de Goede1-9/+60
Some 2-in-1s which use the soc_button_array driver have this ugly issue in their DSDT where the _LID method modifies the irq-type settings of the GPIOs used for the power and home buttons. The intend of this AML code is to disable these buttons when the lid is closed. The AML does this by directly poking the GPIO controllers registers. This is problematic because when re-enabling the irq, which happens whenever _LID gets called with the lid open (e.g. on boot and on resume), it sets the irq-type to IRQ_TYPE_LEVEL_LOW. Where as the gpio-keys driver programs the type to, and expects it to be, IRQ_TYPE_EDGE_BOTH. This commit adds a workaround for this which (on affected devices) does not set gpio_keys_button.gpio on these 2-in-1s, instead it gets the irq for the GPIO, configures it as IRQ_TYPE_LEVEL_LOW (to match how the _LID AML code configures it) and passes the irq in gpio_keys_button.irq.

2020-09-13Input: soc_button_array - add support for INT33D3 tablet-mode switch devicesHans de Goede1-0/+11
According to the Microsoft documentation for Windows 8 convertible devices, these devices should implement a PNP0C60 "laptop/slate mode state indicator" ACPI device. This device can work in 2 ways, if there is a GPIO which directly indicates the device is in tablet-mode or not then the direct-gpio mode should be used. If there is no such GPIO, but instead the events are coming from e.g. the embedded-controller, then there should still be a PNP0C60 ACPI device and event-injection should be used to send the events. The drivers/platform/x86/intel-vbtn.c code is an example from a standardized manner of doing the latter. On various 2-in-1s with either a detachable keyboard, or with 360° hinges, the direct GPIO mode is indicated by an ACPI device with a HID of INT33D3, which contains a single GpioInt in its ACPI resource table, which directly indicates if the device is in tablet-mode or not. This commit adds support for this to the soc_button_array code, as well as for the alternative ID9001 HID which some devices use instead of the INT33D3 HID.

This is a preparation patch for adding support for Intel INT33D3 ACPI devices. These INT33D3 devices follow yet another Intel defined (but not documented) ACPI GPIO button standard. Unlike the ACPI GPIO button devices supported so far, the GPIO used in the INT33D3 devices is active-high, rather then active-low. This commit makes setting the gpio_keys_button.active_low flag configurable through the soc_button_info struct and enables it for all currently supported devices.

Recently a new KEY_SELECTIVE_SCREENSHOT keycode was added by commit 3b059da9835c ("Input: allocate keycode for "Selective Screenshot" key") quoting from the commit message: "New Chrome OS keyboards have a "snip" key that is basically a selective screenshot (allows a user to select an area of screen to be copied). Allocate a keycode for it." Support for this "snip" key seems like it is also a good match for the clipping/snipping tool hotkey, so map this hotkey to the new KEY_SELECTIVE_SCREENSHOT key-code.

Expose model and fw_version via sysfs. Also query the model in probe to make sure, that the I2C communication with the device works before successfully probing the driver. This is a bit complicated, since EETI devices do not have a sync interface. Sending the commands and directly reading does not work. Sending the command and waiting for some time is also not an option, since there might be touch events in the mean time. Last but not least we do not cache the results, since this interface can be used to check the I2C communication is still working as expected.

This adds support for EXC80H60 and EXCH84 controllers, which use a different event type id and have two extra bits for the resolution (so the maximum is 16K instead of 4K).

2020-08-06Input: sentelic - fix error return when fsp_reg_write failsColin Ian King1-1/+1
Currently when the call to fsp_reg_write fails -EIO is not being returned because the count is being returned instead of the return value in retval. Fix this by returning the value in retval instead of count.

2020-08-06Input: alps - remove redundant assignment to variable retColin Ian King1-1/+1
The variable ret is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.

2020-08-06Input: ims-pcu - return error code rather than -ENOMEMColin Ian King1-1/+1
Currently the assignment of -ENOMEM to error is redundant because error is not being read and -ENOMEM is being hard coded as an error return. Fix this by returning the error code in variable 'error'; this also allows the error code from a failed call to input_register_device to be preserved and returned to the caller rather than just returning a possibly inappropriate -ENOMEM. Kudos to Dan Carpenter for the suggestion of an improved fix.

2020-07-28Input: atmel_mxt_ts - only read messages in mxt_acquire_irq() when necessaryNick Dyer1-3/+53
The workaround of reading all messages until an invalid is received is a way of forcing the CHG line high, which means that when using edge-triggered interrupts the interrupt can be acquired. With level-triggered interrupts the workaround is unnecessary. Also, most recent maXTouch chips have a feature called RETRIGEN which, when enabled, reasserts the interrupt line every cycle if there are messages waiting. This also makes the workaround unnecessary. Note: the RETRIGEN feature is only in some firmware versions/chips, it's not valid simply to enable the bit.
