2020-11-17Input: elan_i2c_core - move header inclusion insideLee Jones
The same clause as its use.

2020-11-17Input: ads7846 - drop unneeded asm/irq.h includeDmitry Torokhov
This is essentially a revert of: 3ac8bf077d0f ("[PATCH] ads7846: sparc32 warning fix") By now enable_irq() and disable_irq() are properly defined in linux/interrupt.h and we do not need to pull in architecture-specific bits. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2020-11-17Input: ads7846 - fix unaligned access on 7845Dmitry Torokhov
req->sample[1] is not naturally aligned at word boundary, and therefore we should use get_unaligned_be16() when accessing it. Fixes: 3eac5c7e44f3 ("Input: ads7846 - extend the driver for ads7845 controller support") Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2020-11-17Input: ads7846 - fix integer overflow on Rt calculationOleksij Rempel
In some rare cases the 32 bit Rt value will overflow if z2 and x is max, z1 is minimal value and x_plate_ohms is relatively high (for example 800 ohm). This would happen on some screen age with low pressure. There are two possible fixes: - make Rt 64bit - reorder calculation to avoid overflow The second variant seems to be preferable, since 64 bit calculation on 32 bit system is a bit more expensive. Fixes: ffa458c1bd9b6f653008d450f337602f3d52a646 ("spi: ads7846 driver") Co-developed-by: David Jander <david@protonic.nl> Signed-off-by: David Jander <david@protonic.nl> Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Link: https://lore.kernel.org/r/20201113112240.1360-1-o.rempel@pengutronix.de Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2020-11-17Input: ads7846 - convert to full duplexOleksij Rempel
Starting with 3eac5c7e44f3 ("Input: ads7846 - extend the driver for ads7845 controller support"), the ads7845 was partially converted to full duplex mode. Since it is not touchscreen controller specific, it is better to extend this conversion to cover entire driver. This will reduce CPU load and make driver more readable.

2020-10-04Input: add zinitix touchscreen driverMichael Srba
Add support for the bt541 touchscreen IC from zinitix, loosely based on downstream driver. The driver currently supports multitouch (5 touch points). 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. Based on the similartities between downstream drivers, it seems likely that other similar touchscreen ICs can be supported with this driver in the future.

2020-09-13Input: raydium_i2c_ts - use single i2c_transfer transaction when using ↵Furquan Shaikh
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 Goede
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 Goede
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.
