git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi updates from Mark Brown: "A moderately busy release for SPI, the main core update was the merging of support for multiple chip selects, used in some flash configurations. There were also big overhauls for the AXI SPI Engine and PL022 drivers, plus some new device support for ST.

2024-01-01Input: iqs269a - add support for OTP variantsJeff LaBundy
This patch adds support for each available OTP variant of the device. The OTP configuration cannot be read over I2C, so it is derived from a compatible string instead. Early revisions of the D0 order code require their OTP-enabled func- tionality to be manually restored following a soft reset; this patch accommodates this erratum as well.

2024-01-01Input: iqs269a - add support for slider gesturesJeff LaBundy
This patch adds support for slider gestures that can be expressed by the device. Each gesture (e.g. tap or hold) can be mapped to a unique keycode for either slider 0 or 1. With this change, raw slider coordinates are reported only if the slider has no keycodes defined. This prevents unwanted mouse cur- sor movement when expressing axial gestures (e.g. swipe) and also eliminates some unnecessary I2C traffic. Different revisions of silicon use different tap and swipe timeout step sizes. Apply an appropriate scaling factor depending on which revision is found. To facilitate this change, store the iqs269_ver_info struct in the driver's private data so that other functions can use it after the driver has probed. Last but not least, a former reserved field in iqs269_ver_info now contains useful information; give it a name (fw_num).

This add a mapping for the airplane mode button on the TUXEDO Pulse Gen3. While it is physically a key it behaves more like a switch, sending a key down on first press and a key up on 2nd press. Therefor the switch event is used here. Besides this behaviour it uses the HID usage-id 0xc6 (Wireless Radio Button) and not 0xc8 (Wireless Radio Slider Switch), but since neither 0xc6 nor 0xc8 are currently implemented at all in soc_button_array this not to standard behaviour is not put behind a quirk for the moment.

2023-12-01Input: amimouse - convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-11-30Input: gpio-keys - add system suspend support for dedicated wakeirqsTony Lindgren
Some SoCs have a separate dedicated wake-up interrupt controller that can be used to wake up the system from deeper idle states. We already support configuring a separate interrupt for a gpio-keys button to be used with a gpio line. However, we are lacking support system suspend for cases where a separate interrupt needs to be used in deeper sleep modes. Because of it's nature, gpio-keys does not know about the runtime PM state of the button gpios, and may have several gpio buttons configured for each gpio-keys device instance. Implementing runtime PM support for gpio-keys does not help, and we cannot use drivers/base/power/wakeirq.c support. We need to implement custom wakeirq support for gpio-keys. For handling a dedicated wakeirq for system suspend, we enable and disable it with gpio_keys_enable_wakeup() and gpio_keys_disable_wakeup() that we already use based on device_may_wakeup(). Some systems may have a dedicated wakeirq that can also be used as the main interrupt, this is already working for gpio-keys. Let's add some wakeirq related comments while at it as the usage with a gpio line and separate interrupt line may not be obvious.

2023-11-25Input: atkbd - skip ATKBD_CMD_GETID in translated modeHans de Goede
There have been multiple reports of keyboard issues on recent laptop models which can be worked around by setting i8042.dumbkbd, with the downside being this breaks the capslock LED. It seems that these issues are caused by recent laptops getting confused by ATKBD_CMD_GETID. Rather then adding and endless growing list of quirks for this, just skip ATKBD_CMD_GETID alltogether on laptops in translated mode. The main goal of sending ATKBD_CMD_GETID is to skip binding to ps/2 mice/touchpads and those are never used in translated mode. Examples of laptop models which benefit from skipping ATKBD_CMD_GETID: * "HP Laptop 15s-fq2xxx", "HP laptop 15s-fq4xxx" and "HP Laptop 15-dy2xxx" models the kbd stops working for the first 2 - 5 minutes after boot (waiting for EC watchdog reset?) * On "HP Spectre x360 13-aw2xxx" atkbd fails to probe the keyboard * At least 9 different Lenovo models have issues with ATKBD_CMD_GETID, see: https://github.com/yescallop/atkbd-nogetid This has been tested on: 1. A MSI B550M PRO-VDH WIFI desktop, where the i8042 controller is not in translated mode when no keyboard is plugged in and with a ps/2 kbd a "AT Translated Set 2 keyboard" /dev/input/event# node shows up 2. A Lenovo ThinkPad X1 Yoga gen 8 (always has a translated set 2 keyboard) Reported-by: Shang Ye <yesh25@mail2.sysu.edu.cn> Closes: https://lore.kernel.org/linux-input/886D6167733841AE+20231017135318.11142-1-yesh25@mail2.sysu.edu.cn/ Closes: https://github.com/yescallop/atkbd-nogetid Reported-by: gurevitch <mail@gurevit.ch> Closes: https://lore.kernel.org/linux-input/2iAJTwqZV6lQs26cTb38RNYqxvsink6SRmrZ5h0cBUSuf9NT0tZTsf9fEAbbto2maavHJEOP8GA1evlKa6xjKOsaskDhtJWxjcnrgPigzVo=@gurevit.ch/ Reported-by: Egor Ignatov <egori@altlinux.org> Closes: https://lore.kernel.org/all/20210609073333.8425-1-egori@altlinux.org/ Reported-by: Anton Zhilyaev <anton@cpp.in> Closes: https://lore.kernel.org/linux-input/20210201160336.16008-1-anton@cpp.in/ Closes: https://bugzilla.redhat.com/show_bug.cgi?id=2086156 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20231115174625.7462-1-hdegoede@redhat.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2023-10-27Input: cyttsp5 - add handling for vddio regulatorLin, Meng-Bo
The Cypress touchscreen controllers are often used with external pull-up for the interrupt line and the I2C lines, so we might need to enable a regulator to bring the lines into usable state. Otherwise, this might cause spurious interrupts and reading from I2C will fail. Implement support for a "vddio-supply" that is enabled by the cyttsp5 driver so that the regulator gets enabled when needed.

Can't be hit without the original patch above, but still good to have it fixed - a couple new device IDs in xpad Xbox driver - another quirk for Goodix driver to deal with stuff vendors put in ACPI tables - a fix for use-after-free on disconnect for powermate driver - a quirk to not initialize PS/2 mouse port on Fujitsu Lifebook E5411 laptop as it makes keyboard not usable and the device uses hid-over-i2c touchpad anyways * tag 'input-for-v6.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: powermate - fix use-after-free in powermate_config_complete Input: xpad - add PXN V900 support Input: synaptics-rmi4 - handle reset delay when using SMBus trsnsport Input: psmouse - fix fast_reconnect function for PS/2 mode Revert "Input: psmouse - add delay when deactivating for SMBus mode" Input: goodix - ensure int GPIO is in input for gpio_count == 1 && gpio_int_idx == 0 case Input: i8042 - add Fujitsu Lifebook E5411 to i8042 quirk table Input: xpad - add HyperX Clutch Gladiate Support
