2011-08-02video: tegra: dc: fix hdmi mode filterDonghan Ryu
If there are more than one hdmi modes that have same xres, yres, and vmode, tegra_dc_hdmi_mode_equal can return true even though pixclocks are way different from each other. Now, tegra_dc_hdmi_mode_equal will retun false if pixclock has more than 1Hz of difference. Also, tegra_fb_set_par will use fb_find_nearest_mode instead of fb_find_best_mode to take refresh rate into the consideration.

Refresh rate nearness is not calculated or reset when nearest resolution changes. This patch resets the refresh rate differential measurement whenever a new nearest resolution is discovered. This fixes two error cases; first, wherein the first mode's refresh rate differential is never calculated and second, when the closest refresh rate from a previous nearest resolution is erroneously preserved. back-ported from kernel.org (cherry picked from commit 8917a5603a3e6534d6c75ed0d91077062805b111) Reviewed-on: http://git-master/r/37417 (cherry picked from commit a169b1a92dc1ed4c824569e9dc70267cb1e2eb52) Change-Id: I9757e98053a0676491dfe943f06a0c4946ef96be Signed-off-by: Sanjay Singh Rawat <srawat@nvidia.com> Reviewed-on: http://git-master/r/42390 Reviewed-by: Donghan Ryu <dryu@nvidia.com> Tested-by: Gerrit_Virtual_Submit Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com>

In current implementation, the HSIC port cannot have PHY power off without re-enumeration when it is suspended. This patch will do following upon USB port suspend: * disable the USB PHY clock * disable the shared EMC clock * keep the USB core but running it at 0.95v VDD With this patch, VDD can be reduced to when the HSIC port is suspended. There is no re-enumeration when HSIC port is resumed, also it will not affect the normal LP0 suspend/resume.

2011-07-22tegra: fb: HDMI monitor spec. not correct via "mode" device.Andre Sihera
When monitor is auto-detected on HDMI port, a special structure is initialised to hold the video mode properties for the plugged- in monitor. From this the display string is generated for displa via the "mode" character device under /sys. When the monitor is disconnected, the structures associated with the monitor tself are cleared, but the pointer to the video mode properties structure was left initialised and so pointed into thin air, which resulted in garbage appearing on the "mode" device. Added explicit deinitialisation code to reset pointer to video mode properties so "cat mode" within /sys yields an empty string when the HDMI monitor is unplugged.

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.

Dvc I2C_DONE_INTR_EN interrupt bit is always enable into dvc control register3.During normal transaction on dvc i2c bus sometimes one transaction written two times in TX fifo buffer because of triggered dvc interrupt.This is causing to corrupt the next transaction header and send wrong address over dvc i2c bus.To solve this issue dvc i2c interrupt has to disable during filling of Tx fifo and enable after that. Writing last packet into Tx Fifo is generating i2c interrupt immediately if IE bit is enable in Packet header. Data shared between isr and normal thread are not in sync. So alway update these data before writing into Tx fifo. Updated the following things in code: (1) Add the code to mask/unmask I2C_DONE_INTR_EN into dvc control reg3 (2) Always updates the i2c driver required field structure data before writing into Tx Fifo register. (3) Add the code to handle tx fifo overflow condition also.

2011-06-16usb: gadget: composite: Allow function drivers to pause control transfersRakesh Bodla
Some USB function drivers (e.g. f_mass_storage.c) need to delay or defer the data/status stages of standard control requests like SET_CONFIGURATION or SET_INTERFACE till they are done with their bookkeeping and are actually ready for accepting new commands to their interface. They can now achieve this functionality by returning USB_GADGET_DELAYED_STATUS in their setup handlers (e.g. set_alt()). The composite framework will then defer completion of the control transfer by not completing the data/status stages. This ensures that the host does not send new packets to the interface till the function driver is ready to take them. When the function driver that requested for USB_GADGET_DELAYED_STATUS is done with its bookkeeping, it should signal the composite framework to continue with the data/status stages of the control transfer. It can do so by invoking the new API usb_composite_setup_continue(). This is where the control transfer's data/status stages are completed and host can initiate new transfers. The DELAYED_STATUS mechanism is currently only supported if the expected data phase is 0 bytes (i.e. w_length == 0). Since SET_CONFIGURATION and SET_INTERFACE are the only cases that will use this mechanism, this is not a limitation.
