Subject: [PATCH] overlays: ghost-amp: Change early-disable sequence
|
|
|
|
In the event that the ENABLE signal from the codec goes low before
|
|
RELAY2 has been enabled, wait until the full 1000ms has elapsed then
|
|
enable RELAY2 and jump to amp_on_wait, i.e. as if output had been
|
|
fully enabled then disabled, rather than returning to the amp_off
|
|
idle state.
