enable CONFIG_INPUT_JOYDEV on all Qualcomm devices

[aanze]

The Linux Gamepad API gamepad detection via navigator.getGamepads()) requires /dev/input/js* device nodes, which are provided by the joydev kernel driver.

Without CONFIG_INPUT_JOYDEV, the evdev events from gamepads (including those exposed as virtual controllers by InputPlumber) are not accessible through the HTML5 Gamepad API. This breaks gamepad input in Electron-based applications such as OpenNOW, cloud-gaming launchers, and any web-based emulator frontend.

All other ROCKNIX platforms (Rockchip RK3326/RK3399/RK3566/RK3576/RK3588, Amlogic S922X, Allwinner) already enable JOYDEV. This change aligns the Qualcomm SoCs (SM6115, SM8250, SM8550, SM8650, SM8750) and H700 with the rest of the tree.

Diagnosed and tested on AYN Odin 3 (SM8750) with OpenNOW v0.3.9: with CONFIG_INPUT_JOYDEV=y, /dev/input/js* nodes appear correctly and the Gamepad API exposes the InputPlumber-emulated DualSense controller as a standard mapped gamepad to Chromium.

Summary

Enables CONFIG_INPUT_JOYDEV on all Qualcomm devices and H700, aligning them with the rest of the supported platforms.

Problem

The Linux Gamepad API (used by Electron/Chromium apps for HTML5 gamepad detection via navigator.getGamepads()) requires /dev/input/js* device nodes, which are provided by the joydev kernel driver.

Without CONFIG_INPUT_JOYDEV, evdev events from gamepads (including the virtual controllers emulated by InputPlumber) are not accessible through the HTML5 Gamepad API. This breaks gamepad input in Electron-based applications such as:

• OpenNOW (community GeForce NOW client)
• Cloud-gaming launchers
• Web-based emulator frontends

Current state in the tree

Platform	JOYDEV
Rockchip RK3326, RK3399, RK3566, RK3576	=y
Rockchip RK3588	=m
Amlogic S922X	=y
Allwinner (global)	=y
Amlogic (global)	=y
Qualcomm SM6115, SM8250, SM8550, SM8650, SM8750	disabled
H700	disabled (despite Allwinner global being =y)

This PR sets CONFIG_INPUT_JOYDEV=y on the 6 affected configs to match the majority.

Testing

Tested on AYN Odin 3 (SM8750) with OpenNOW v0.3.9 (Electron-based GeForce NOW client):

• Before: navigator.getGamepads() returns [null, null, null, null] regardless of input activity; /dev/input/ contains only event* nodes, no js*.
• After (verified by manually loading a out-of-tree joydev.ko compiled from the same kernel sources): /dev/input/js* nodes appear, and Chromium exposes the InputPlumber-emulated DualSense as a standard mapped gamepad. OpenNOW responds correctly to gamepad input.

I have not been able to test the other Qualcomm SoCs and H700, but the change is mechanical and identical to what already works on Rockchip/Amlogic/Allwinner.

AI Usage

While ROCKNIX doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it

Did you use AI tools to help write this code? PARTIALLY
AI was used to identify the cause of the gamepad not being detected in OpenNow application.

Just hopping in to say good change! Now controller input works in Heroic Games Launcher. (I was wondering why it wasn't working before)

LGTM.

This will be queued for next week, se we'll have a full month to check for any unwanted sides effet. (I don't expect any)
