+ ---help---
+ Say Y here if you want to support Dell AIO UART backlight interface.
+ The Dell AIO machines released after 2017 come with a UART interface
+ to communicate with the backlight scalar board. This driver creates
+ a standard backlight interface and talks to the scalar board through
+ UART to adjust the AIO screen brightness.
+
+ To compile this driver as a module, choose M here: the module will
+ be called dell_uart_backlight.
