Merge patch series "led: remove unused legacy LED code"
Quentin Schulz <[email protected]> says:
Only the Siemens corvus board seems to be using these two status LEDs
from the legacy LED API.
Since we're trying to get rid of the last users of the legacy LED API,
let's migrate Corvus to the modern LED API instead, which uses DM. For
Corvus's case, it also uses DM_GPIO (already enabled in defconfig).
Since there was no use for the green status_led (not compiled in), it
simply is removed without migrating it to the modern API. If need be, we
can always add a new gpio-led in the FDT.
Note that I do not own a Siemens Corvus board so it's a bit of a shot in
the dark whether it'll work on the first try, only build tested.
The red LED should be on whenever reaching U-Boot proper CLI, if not we
have an issue.
The LED should be controllable with the led command from U-Boot proper
CLI.
