This patch seems already in your "master" branch
(5c189208b606a85b4e97109af70d59f10a42fdfd).
Do you want me to rebase this patch or do you mange merging with "AT91:
fix use of clock disable on idle for AT91x40 devices"
(cb809b1a5ebffca8cf0314b788919989e8e4ab5f) ?
already in your "devel" and "devel-stable" branches?
Best regards,
