dt-bindings: connector: add pd-disable dependency

2026-04-11T12:19:31+00:00

commit 269c26464dcf8b54b0dd9c333721c30ee44ae297 upstream. When Power Delivery is not supported, the source is unable to obtain the current capability from the Source PDO. As a result, typec-power-opmode needs to be added to advertise such capability.

dt-bindings: auxdisplay: ht16k33: Use unevaluatedProperties to fix common property warning

hwmon: (peci/cputemp) Fix crit_hyst returning delta instead of absolute temperature

2026-04-02T11:07:25+00:00

commit 0adc752b4f7d82af7bd14f7cad3091b3b5d702ba upstream. The hwmon sysfs ABI expects tempN_crit_hyst to report the temperature at which the critical condition clears, not the hysteresis delta from the critical limit. The peci cputemp driver currently returns tjmax - tcontrol for crit_hyst_type, which is the hysteresis margin rather than the corresponding absolute temperature. Return tcontrol directly, and update the documentation accordingly.

hwmon: (adm1177) fix sysfs ABI violation and current unit conversion

2026-04-02T11:07:23+00:00

[ Upstream commit bf08749a6abb6d1959bfdc0edc32c640df407558 ] The adm1177 driver exposes the current alert threshold through hwmon_curr_max_alarm. This violates the hwmon sysfs ABI, where *_alarm attributes are read-only status flags and writable thresholds must use currN_max. The driver also stores the threshold internally in microamps, while currN_max is defined in milliamps. Convert the threshold accordingly on both the read and write paths. Widen the cached threshold and related calculations to 64 bits so that small shunt resistor values do not cause truncation or overflow. Also use 64-bit arithmetic for the mA/uA conversions, clamp writes to the range the hardware can represent, and propagate failures from adm1177_write_alert_thr() instead of silently ignoring them. Update the hwmon documentation to reflect the attribute rename and the correct units returned by the driver.

usb: core: new quirk to handle devices with zero configurations

2026-04-02T11:07:16+00:00

[ Upstream commit 9f6a983cfa22ac662c86e60816d3a357d4b551e9 ] Some USB devices incorrectly report bNumConfigurations as 0 in their device descriptor, which causes the USB core to reject them during enumeration. logs: usb 1-2: device descriptor read/64, error -71 usb 1-2: no configurations usb 1-2: can't read configurations, error -22 However, these devices actually work correctly when treated as having a single configuration. Add a new quirk USB_QUIRK_FORCE_ONE_CONFIG to handle such devices. When this quirk is set, assume the device has 1 configuration instead of failing with -EINVAL. This quirk is applied to the device with VID:PID 5131:2007 which exhibits this behavior.

hwmon: (aht10) Add support for dht20

[ Upstream commit 3eaf1b631506e8de2cb37c278d5bc042521e82c1 ] Add support for dht20 temperature and humidity sensor from Aosong. Modify aht10 driver to handle different init command for dht20 sensor by adding init_cmd entry in the driver data. dht20 sensor is compatible with aht10 hwmon driver with this change. Tested on TI am62x SK board with dht20 sensor connected at i2c-2 port.

ASoC: dt-bindings: asahi-kasei,ak5558: Fix the supply names

2026-03-04T12:20:29+00:00

commit 80ca113671a005430207d351cb403c1637106212 upstream. In the original txt format binding document ak4458.txt, the supply names are 'AVDD-supply', 'DVDD-supply', and they are also used in driver. But in the commit converting to yaml format, they are changed to 'avdd-supply', 'dvdd-supply'. After search all the dts file, these names 'AVDD-supply', 'DVDD-supply', 'avdd-supply', 'dvdd-supply' are not used in any dts file. So it is safe to fix the yaml binding document.
