To support input device lights manager feature in frameworks, provide sysfs node access to system server process. DD: go/pk_backlight_control (For keyboard backlight control for external keyboards) Similar CL: ag/20102346 Kernel provides a standardized LED interface to expose LED controls over sysfs: https://docs.kernel.org/leds/leds-class.html The feature will be provided for devices with kernel sysfs class led support and vendor kernel driver for input controllers that do have lights. The kernel sysfs class led support is a kernel config option (LEDS_CLASS), and an input device driver will create the sysfs class node interface. By giving system_server the access to these sysfs nodes, the feature will work on devices with the kernel option and kernel input/hid driver support. We do use CTS tests to enforce the kernel options and the input device drivers. What's already supported: - We already expose paths for UHID based LED nodes which covers all bluetooth based peripherals that have custom vendor drivers to expose LED sysfs nodes. (see CL aosp/1546377) What's included in this CL: - Exposing paths for sysfs nodes for external USB based devices that expose LED nodes using vendor specific drivers using standard LED interface provided by Kernel - We are using specific paths for USB devices instead of /sys/class/leds to avoid giving access to system LED nodes that would also appear under /sys/class/leds (see discussion in aosp/1546377) NOTE: Light HAL should never touch the HID device sysfs light, as the light HAL only defines a number of lights supported (https://android.googlesource.com/platform/hardware/interfaces/+/master/light/2.0/types.hal) but not include input device lights, so we shouldn't have conflict for managing these lights. NOTE: External keyboard backlight is different for HAL light type KEYBOARD which is for devices with attached keyboards.
