2.6.37-stable review patch. If anyone has any objections, please let us know.
------------------ From: Rajkumar Manoharan <[email protected]> commit 5b64aa72ead6f8be488d2be7af579f0d69fb7a6e upstream. The bit 6 & 7 of AR_WA (0x4004) should be enabled only for the chips that are supporting L0s functionality while resuming back from S3/S4. Enabling these bits for AR9280 is causing system hang within a few S3/S4-resume cycles. Cc: Jack Lee <[email protected]> Signed-off-by: Rajkumar Manoharan <[email protected]> Signed-off-by: John W.
