Hi. I see several platform-data headers that are not used in upstream. For instance, please look at this driver: drivers/leds/leds-netxbig.c If I understood it correctly, this driver supports both device tree and legacy board-file. I grepped 'netxbig_led_platform_data', but I only found the driver and platform_data header. No board-file in upstream. masahiro@grover:~/ref/linux$ git grep netxbig_led_platform_data drivers/leds/leds-netxbig.c: struct netxbig_led_platform_data *pdata, drivers/leds/leds-netxbig.c: struct netxbig_led_platform_data *pdata) drivers/leds/leds-netxbig.c: struct netxbig_led_platform_data *pdata) drivers/leds/leds-netxbig.c: struct netxbig_led_platform_data *pdata = dev_get_platdata(&pdev->dev); include/linux/platform_data/leds-kirkwood-netxbig.h:struct netxbig_led_platform_data { So, what shall we do? Drop the board-file support? Or, keep it in case somebody is still using their board-files in downstream? -- Best Regards Masahiro Yamada
