2011-03-02tegra: host: move stale wait checking into the kernelPrajakta Gudadhe
The kernel now receives wait tracking data (similar to gathers and relocs) and compares the current syncpt with the threshold value. If it's old, it gets a kernel mapping and rewrites the method data to use a kernel reserved syncpt that is always 0 (so trivially pops when seen by the HW). Patch has dependency to the user-space patches Submitted on behalf of: Chris Johnson <cjohnson@nvidia.com> original work by: Chris Johnson <cjohnson@nvidia.com> Change-Id: I4d4e5d3b49cab860485c4172f87247f5b4f5ea6e

2011-02-24[ARM] tegra: hdmi nvhdcp driverJon Mayo
Device /dev/nvhdcpX is used to manage NVHDCP on framebuffer /dev/fbX. These devices are created on hdmi driver initialition when it is attached to dc. Currently only one nvhdcp device may be created. An ioctl interface is in video/nvhdcp.h Check for repeaters and store repeater info. userspace application queries this status to authenticate the connection. When authentication fails, auto-renegotiate every 1.75 seconds. Give up after 5 failed attempts, reset after hotplug or policy change. use TEGRA_DC_OUT_NVHDCP_POLICY_ON_DEMAND in tegra_dc_out.flags in board panel configuration to select a different default policy at probe. Currently only TEGRA_DC_OUT_NVHDCP_POLICY_ALWAYS_ON is supported.

2011-02-11Revert "mmc: subtract boot sectors from disk size for eMMC 4.3+ devices"Colin Cross
This reverts commit 2cdc235bbeb09b2b78cd02a94ab79c265861aea9. The reverted commit incorrectly calculates the size of eMMC devices in some (all?) cases.

2011-02-08USB: ehci: tegra: Align DMA transfers to 32 bytesRobert Morell
The Tegra2 USB controller doesn't properly deal with misaligned DMA buffers, causing corruption. This is especially prevalent with USB network adapters, where skbuff alignment is often in the middle of a 4-byte dword. To avoid this, allocate a temporary buffer for the DMA if the provided buffer isn't sufficiently aligned. Signed-off-by: Robert Morell <rmorell@nvidia.com>
2011-02-08USB: HCD: Add driver hooks for (un)?map_urb_for_dmaRobert Morell
Provide optional hooks for the host controller driver to override the default DMA mapping and unmapping routines. In general, these shouldn't be necessary unless the host controller has special DMA requirements, such as alignment contraints. If these are not specified, the general usb_hcd_(un)?map_urb_for_dma functions will be used instead. Also, pass the status to unmap_urb_for_dma so it can know whether the DMA buffer has been overwritten. Finally, add a flag to be used by these implementations if they allocated a temporary buffer so it can be freed properly when unmapping.

2011-02-08USB: HCD: Add usb_hcd prefix to exported functionsRobert Morell

2011-01-14video: tegra: host: disable MPE auto-power-gateMayuresh Kulkarni
It is seen that auto-power-gate of MPE causes some issues when long run camera stress test is run. The issue manifest itself in the form of MPE sync-point not getting triggered from hardware and hence the caller who is waiting on it hangs up the system. Disabling auto-power-gate for MPE seems to resolve this issue.
