From 9c482946235362f81bf20da94e1c1f467a03c08f Mon Sep 17 00:00:00 2001 From: Svyatoslav Ryhel Date: Sat, 25 Apr 2026 15:54:29 +0300 Subject: misc: Remove old APDS990x driver The APDS990x driver in misc lacks DeviceTree support, and no mainline pre-DT board files configured this device using apds990x_platform_data. This driver belongs to a legacy group of ambient light sensor drivers in drivers/misc/ that predates the migration to DT and the standard IIO ABI. Since the Avago APDS9900/9901 ALS/Proximity sensor is now supported by the tsl2772 IIO driver and there are no active users in the kernel tree, remove this old implementation.

The `kb_wake_angle` attribute should only be visible if the sensor hub detects two or more accelerometers. If cros_ec_sysfs_probe() runs before cros_ec_sensorhub_register() completes sensor enumeration, the sysfs attributes are created while `has_kb_wake_angle` is still false, hiding `kb_wake_angle` incorrectly. Store the created attribute group pointer in `ec_dev->group`. When the sensor hub completes sensor enumeration, it checks for this group and calls sysfs_update_group() to notify the sysfs core to re-evaluate attribute visibility. This ensures the `kb_wake_angle` attribute visibility is correctly updated regardless of the driver probe order.

Add a small PROM21 PCI glue driver for AMD 1022:43fc and 1022:43fd controllers. The glue delegates USB host operation to the common xhci-pci core and publishes a "hwmon" auxiliary device with parent-provided MMIO data. Auxiliary device creation failure is logged but does not fail the xHCI probe. Make the PROM21 glue a hidden Kconfig tristate driven by the user-visible SENSORS_PROM21_XHCI option. If sensor support is disabled, generic xhci-pci binds PROM21 controllers normally. If sensor support is enabled, the glue follows USB_XHCI_PCI. This keeps the auxiliary device available for a modular sensor driver while avoiding a built-in xhci-pci core handing PROM21 controllers to a glue driver that is only available as a module during initramfs.

This devid does not follow the standard DSTS convention: PRESENCE_BIT (0x00010000) encodes the insert state rather than feature presence, and STATUS_BIT is never set. Presence of a keystone slot is detected by a successful DSTS call.

To stop mixing up different and unrelated driver( type)s let the subsystem headers only use the subset of the recently split that are relevant for them. The fallout (I hope) is addressed in the previous commits that handle sources relying on e.g. pulling in the full legacy header and thus providing pci_device_id.
