Also... do we need both "current" and "max-current" properties? But regulators already have "regulator-max-microamp" property. So what about: max-microamp : maximum intensity in microamperes of the LED (torch LED for flash devices) max-flash-microamp : initial intensity in microamperes of the flash LED; it is required to enable support for the flash led flash-timeout-microseconds : timeout in microseconds after which flash led is turned off If you had indicator on the same led, I guess indicator-microamp : recommended intensity in microamperes of the LED for indication ...would do? > I propose to avoid name "torch", as for ordinary leds it would > be misleading. Agreed.
