There has been an LED framework in U-Boot which uses driver model for about 9 years now. Recent work is underway to improve it and provide more features. It is probably a good time to drop the old code, which is only used by 5 boards:
./tools/qconfig.py -f LED_STATUS 5 matches eb_cpu5282 eb_cpu5282_internal mx23_olinuxino pinephone socfpga_vining_fpga
This series attempts that.
The new /options node provides a way to provide U-Boot settings, and LEDs are implemented there. For now I have brought into the options schema from upstream. We can update it once the LED additions land there.
Changes in v3: - Update commit message - Combine removal and enable patches - Combine removal and enable patches - Combine removal and enable patches
Changes in v2: - Combine code-removal and defconfig changes - Add a patch to enable LED and LED_BOOT for these boards - Enable LED on the 5 affected platforms - Reorder patches for bisectability - Add dt-schema bindings for LED
