[PATCH 4/5] omap: GPIO: fix auto-disable of debounce clock

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Kevin Hilman <khilman@xxxxxxxxxxxxxxxxxxx>

The addition of the new debounce code (commit
168ef3d9a56bd8bffe0ef4189c450888b4aefefe) broke the auto-disable of
debounce clocks on idle by forgetting to update the debounce clock
enable mask.

Add back the updating of bank->dbck_enable_mask so debounce clocks are
auto-disabled.
