2025-03-04HID: amd_sfh: Allow configuring whether HPD is enabled or disabledMario Limonciello
Human presence detection (HPD) sensor uses a camera to determine when user is physically in front of the machine. This might not be a desirable behavior because it can (for example) cause the machine to wake on approach. Add a new sysfs file "hpd" that will control whether this sensor is enabled. Use the value of this sysfs file to turn off HPD and prevent it from re-enabling after resume from suspend.

2025-01-09HID: amd_sfh: Add support to export device operating statesBasavaraj Natikar
Add support to export device operating states, such as laptop placement, platform types and propagate this data to AMD PMF driver for use in actions. To retrieve the device operating states data, SRA sensor support need to be enabled in AMD SFH driver. So add support to enable the SRA sensor. Also, remove explicit assignments to sensor_index enum.

2024-02-27HID: amd_sfh: Improve boot time when SFH is availableBasavaraj Natikar
AMD SFH load takes longer time in initialization. Hence split and defer initialization code to improve SFH module load time and boot time of the system when SFH is available. Signed-off-by: Basavaraj Natikar <Basavaraj.Natikar@amd.com> Signed-off-by: Jiri Kosina <jkosina@suse.com>
2024-01-04HID: amd_sfh: Add a new interface for exporting ALS dataBasavaraj Natikar
AMDSFH has information about the Ambient light via the Ambient Light Sensor (ALS) which is part of the AMD sensor fusion hub. Add a new interface to export this information, where other drivers like PMF can use this information to enhance user experiences.

2022-07-21HID: amd_sfh: Implement SFH1.1 functionalityBasavaraj Natikar
Newer AMD SOCs use SFH1.1 memory access with new PCI-id. Hence add new sfh1_1 sub directory to implement SFH1.1 functionality by defining new PCI id, interface functions, descriptor functions and handlers which invokes sfh1.1.
