HID: amd_sfh: Handle condition of "no sensors" for SFH1.1

2022-09-30T08:31:18Z

Based on num_hid_devices, each sensor device registers to HID. If "no sensors" then amd_sfh work initialization and scheduling doesn’t make sense and return ENODEV to stop driver probe. Hence add a check for num_hid_devices to handle special case in the situation of "no sensors" for SFH1.1.

HID: amd_sfh: Change dev_err to dev_dbg for additional debug info

2022-09-30T08:31:18Z

Users should only be notified at most one time on systems doesn't have any sensors connected or non-supported systems. Check the return code and don't display error messages in those conditions. Signed-off-by: Basavaraj Natikar Signed-off-by: Jiri Kosina

HID: AMD_SFH: Add a DMI quirk entry for Chromebooks

2022-08-25T09:42:54Z

Google Chromebooks use Chrome OS Embedded Controller Sensor Hub instead of Sensor Hub Fusion and leaves MP2 uninitialized, which disables all functionalities, even including the registers necessary for feature detections. The behavior was observed with Lenovo ThinkPad C13 Yoga. Signed-off-by: Akihiko Odaki Suggested-by: Mario Limonciello Acked-by: Basavaraj Natikar Signed-off-by: Jiri Kosina

HID: amd_sfh: Implement SFH1.1 functionality

2022-07-21T11:44:04Z

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. Signed-off-by: Basavaraj Natikar Signed-off-by: Jiri Kosina
