2025-06-02button: qcom-pmic: allow to specify code in devicetreeAlexey Minnekhanov
Most device vendors put "Volume Down" button onto PMIC RESIN. But Sony is special: see dts/upstream/src/arm64/qcom/sdm630-sony-xperia-nile.dtsi or [1]. They put "Volume Down" on PMIC GPIO 7 where others usually put "Volume Up", and KEY_VOLUMEUP is inside &pon_resin. Currently if you boot U-Boot on such Sony device, you end up with 2 "Volume Down" buttons, and no "Volume Up", which makes navigating menu problematic. Support reading devicetree "linux,code" property and override statically defined button code & label based on that.

2025-04-11button: make button_get_by_label() case insensitiveCaleb Connolly
This function is already doing a fuzzy match, since there are no guarantees that a given label is unique. Ignoring case makes it much easier to catch "Volume down" or "Volume Down" in board-agnostic code.

2025-04-11button: qcom-pmic: prettify and standardise button labelsCaleb Connolly
Boards using gpio-keys for volume buttons label them "Volume Down", let's match that here, and make the power button nicer too. This simplifies configuring button_cmds in a board-agnostic way.

This helps with reliability on some platforms. We should probably also configure the hardware debounce timer eventually. Link: https://lore.kernel.org/r/20241113045109.1838241-1-caleb.connolly@linaro.org Signed-off-by: Caleb Connolly <caleb.connolly@linaro.org>
2024-12-04button: gpio: handle broken controllerCaleb Connolly
Avoid crashing U-Boot when the GPIO controller for a button is disabled or failed to probe. We also need to check the priv data for each button since even if a button fails to probe it will still be polled by the core code. Signed-off-by: Caleb Connolly <caleb.connolly@linaro.org>
2024-11-16dm: button: support remapping phone keysCaleb Connolly
We don't have audio support in U-Boot, but we do have boot menus. Add an option to re-map the volume and power buttons to up/down/enter so that in situations where these are the only available buttons (such as on mobile phones) it's still possible to navigate menus built in U-Boot or an external EFI app like GRUB or systemd-boot.

2022-02-11button: adc: set state to pressed when the voltage is closest to nominalPeter Cai
In the Linux implementation of adc-keys (drivers/input/keyboard/adc-keys.c), `press-threshold-microvolt` is not really interpreted as a threshold, but rather as the "nominal voltage" of the button. When the voltage read from the ADC is closest to a button's `press-threshold-microvolt`, the button is considered pressed. This patch reconciles the behavior of button-adc with Linux's adc-keys such that device trees can be synchronized with minimal modifications. Signed-off-by: Peter Cai <peter@typeblog.net>

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>
