* net: wimax: suspend and resume issue in JBsangamanatha2012-05-101-0/+18
| | | | | | | Added suspend and resume handlers in wimax driver. This will avoid sdio power off during suspend. Signed-off-by: sangamanatha <sangam.swamy@samsung.com>
* net: wimax: Padding problem fix.JP Abgrall2012-04-091-3/+1
| | | | | | | | skb.len adjustment on 64 byte boundary is not needed. Some sites and ping test resulted in packet send fail. Change-Id: Ic2cb5db9c732838ba4ca0c5ba44078bbecae75e7 Signed-off-by: sangamanatha <sangam.swamy@samsung.com>
* net: wimax: driver panic because of mmc debug logsangamanatha2012-04-092-1/+5
| | | | | | | | | | | | | | | | Wimax driver probe function set the firmware download timeout to 5sec. The debug logs in mmc/sdhc, results into f/w download timeout. But the receive thread continue to download the f/w image which is freed in probe function. 1. Increased the firmware download timeout to 12sec to include the debug output delays. 2. Released the receive thread immediately in case of f/w download timeout and before freeing the f/w image(wimax_image.data).

* net: wimax: fix system process not responding ANR.JP Abgrall2012-04-095-2/+21
| | | | | | | | | | | | | | | | | | | | This patch fixes the issue "5704273 system process not responding ANR every time after soft reboot of device". Issue can be reproduced by soft rebooting the device: adb root adb shell stop adb shell start The ANR was due to wimax power on fail due to wimax firmware download failure. The modem was not responding after driver send MSG_DRIVER_OK_REQ during f/w download process. The issue is fixed by retrying the MSG_DRIVER_OK_REQ again after waiting for 100ms, in case failed to get MSG_DRIVER_OK_RESP.

| | | | | | | | Added mutex_trylock to check device busy state. added wake_lock to avoid suspend during send. Change-Id: Iaae7c952b3718e66e50eb26639415e4afc4b3d22 Signed-off-by: sangamanatha <sangam.swamy@samsung.com>
* Revert "net: wimax: prevent dpm timeout in send during suspend"sangamanatha2011-11-172-8/+10
| | | | | | | | | The removed mutex has an importance in maintaining concurrency in send and suspend code. So will be keeping the mutex and adding mutex_trylock in suspend code. This reverts commit 7b3fa7a7bf7027a8effa3cbe927e59d553a4503b.
