Input: iqs7222 - preserve system status register

2025-03-10T06:12:07Z

Some register groups reserve a byte at the end of their continuous address space. Depending on the variant of silicon, this field may share the same memory space as the lower byte of the system status register (0x10). In these cases, caching the reserved byte and writing it later may effectively reset the device depending on what happened in between the read and write operations. Solve this problem by avoiding any access to this last byte within offending register groups. This method replaces a workaround which attempted to write the reserved byte with up-to-date contents, but left a small window in which updates by the device could have been clobbered. Now that the driver does not touch these reserved bytes, the order in which the device's registers are written no longer matters, and they can be written in their natural order. The new method is also much more generic, and can be more easily extended to new variants of silicon with different register maps. As part of this change, the register read and write functions must be gently updated to support byte access instead of word access.

Input: i8042 - swap old quirk combination with new quirk for more devices

2025-02-25T21:01:51Z

Some older Clevo barebones have problems like no or laggy keyboard after resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE quirk. We could not activly retest these devices because we no longer have them in our archive, but based on the other old Clevo barebones we tested where the new quirk had the same or a better behaviour I think it would be good to apply it on these too.

Input: i8042 - swap old quirk combination with new quirk for several devices

2025-02-25T21:01:51Z

Some older Clevo barebones have problems like no or laggy keyboard after resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE quirk. While the old quirk combination did not show negative effects on these devices specifically, the new quirk works just as well and seems more stable in general.

Input: i8042 - add required quirks for missing old boardnames

2025-02-25T21:01:51Z

Some older Clevo barebones have problems like no or laggy keyboard after resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE quirk. The PB71RD keyboard is sometimes laggy after resume and the PC70DR, PB51RF, P640RE, and PCX0DX_GN20 keyboard is sometimes unresponsive after resume. This quirk fixes that.

Some older Clevo barebones have problems like no or laggy keyboard after resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE quirk. With the old i8042 quirks this devices keyboard is sometimes laggy after resume. With the new quirk this issue doesn't happen.

Input: xpad - rename QH controller to Legion Go S

2025-02-25T16:10:23Z

The QH controller is actually the controller of the Legion Go S, with the manufacturer string wch.cn and product name Legion Go S in its USB descriptor. A cursory lookup of the VID reveals the same. Therefore, rename the xpad entries to match.

Input: xpad - add support for TECNO Pocket Go

2025-02-25T16:10:22Z

TECNO Pocket Go is a kickstarter handheld by manufacturer TECNO Mobile. It poses a unique feature: it does not have a display. Instead, the handheld is essentially a pc in a controller. As customary, it has an xpad endpoint, a keyboard endpoint, and a vendor endpoint for its vendor software.

2025-02-25T16:10:21Z

ZOTAC Gaming Zone is ZOTAC's 2024 handheld release. As it is common with these handhelds, it uses a hybrid USB device with an xpad endpoint, a keyboard endpoint, and a vendor-specific endpoint for RGB control et al.

Input: goodix-berlin - fix vddio regulator references

2025-02-25T06:28:50Z

As per dt-bindings the property is called vddio-supply, so use the correct name in the driver instead of iovdd. The datasheet also calls the supply 'VDDIO'.
