2011-11-30nvhost: Do not crash if wait syncpt > maxTerje Bergstrom
If user space is waiting for a syncpt value higher than max, nvhost_wait_timeout() panics the kernel. This panic is based on the assumption that nobody should wait for sync points higher than indicated by a submit from user space. As the API has nothing to disallow waiting for future sync points not indicated by any submit, this patch removes the panic and treats this as a normal case.

2011-11-30video: tegra: dc: Reduce usage count of nvmap clientVandana Salve
Carveout memory leak occured in video playback on abnormal termination as the tegra overlay driver didn't had the implementation to reduce the usage count of nvmap client on device closure. Hence on abnormal termination of mediaserver, the carveout memory remained allocated causing memory leak. The usage count of nvmap client for overlay driver is incremented on ioctl TEGRA_OVERLAY_IOCTL_SET_NVMAP_FD.It should be decremented on device closure. Added the code to decrement the uage count of nvmap client on release, so that the client and the carveout memory is free'd whenever the count reaches zero on successful as well as abnormal termination of mediaserver process. Similar implementation is done by NvHost channel driver, The NvHost drivers takes care of nvmap client usage count.i.e. decrement the uasge count of nvmap client which is incremented by NVHOST_IOCTL_CHANNEL_SET_NVMAP_FD ioctl.

2011-11-30video: tegra: host: separate the different kinds of ACM timeoutsChris Johnson
Let the delay in making sure a module is idle for some amount of time before powering it down be module specific. This typically occurs at the end of a INTR_ACTION_SUBMIT_COMPLETLETE. Some modules have more work (e.g. 3D) to power down, so should have a longer delay than a module with a lower latency (e.g. 2D). This change adds the infrastructure a subsequent change will assign different values. Make use of a separate #define for the timeout used in waiting for a system suspend to go idle.

2011-11-30tegra: dc: adding max pixclock check for hdmiDonghan Ryu
tegra_dc_hdmi_equal doesn't check pixclock and some devices doesn't support 148.5Mhz pixclock which is needed for 1080p@60. However, adding 1080p@30 to the supported hdmi mode array makes tegra_dc_hdmi_equal to retun 1080p@60. Therefore, this commit adds max pixclock check to distinguish modes with different pixclock Bug: 815409 Original-Change-Id: Ifbf07929e3c7a92172856518a55e9d4a04f0b943 Reviewed-on: http://git-master/r/32511 Reviewed-by: Niket Sirsi <nsirsi@nvidia.com> Tested-by: Niket Sirsi <nsirsi@nvidia.com> Rebase-Id: R5b3c53a840ea0855d4298d92ec8db696a0c2f40e
