Hi,
While discussing that change internally. One remark was that the
brightness of the LED controller is being set at every state change
while in principle, a "default" brightness could be set once and for
all, for instance in the probing function.
Currently, the U-Boot LED driver does not support
When setting the LED state (OFF, ON or blinking), the default
maximum brightness is set for ON and blinking state and the
brightness is set to 0 for OFF state.
This should make sure the LED controller's registers affecting the
brightness are correctly initialized and should give consistent
behaviou
