This issue happens when multiple thread is trying to idle GPU at the same time, root cause is some wrong logic related with powerMutex which cause cpu still access GPU AHB register after GPU is suspend(clock off), that cause the bus lockup and make the whole system hang.

2014-04-01ENGR00303543 usb: ehci-arc: do noop during resume if it is not in host modePeter Chen
We find a bug that the usb will produce endless interrupt during the resume after below steps: - nothing connected at usb otg port, but enable usb gadget driver - system enters suspend - plug in usb cable - system leaves suspend The reasons of endless interrupt is: the host controller resume routine leaves the phy low power mode, but device controller resume routine has still not been called, so the software considers it is still at low power mode. After this time, the vbus change interrupt comes, the wakeup routine considers it is an wakeup interrupt, but in fact it is not. So, the endless interrupt occurs. The solution of this problem is do noop during host controller resume routine if current usb mode is not host mode, and the device controller reusme routine will handle it.

2014-03-25ENGR00304402 video: mxc LDB: Enable LDB channel after display controllerLiu Ying
In order to avoid any random pixelation issue, we should follow a correct display controller/LDB initialization sequence, that is, LDB channel should be enabled after its relevant display controller is enabled. Since the enable() callback of the mxc display driver is called after a display controller is enabled, this patch uses the enable()/disable() callbacks to replace the fb notifier callback implemented in the LDB driver. Also, we disable a LDB channel in the setup() callback of the mxc display driver to make sure of the correct sequence in any fb set_par() function. As the enable()/disable() callbacks are always invoked with fb_blank(), this patch drops the suspend()/resume() functions of the LDB driver which do nothing but enable/disable LDB channels. We also remove the code to enable ldb di clocks because they can be enabled when their relevant child pixel clocks are enabled.

2014-03-10rtnetlink: Compute and store minimum ifinfo dump sizeGreg Rose
commit c7ac8679bec9397afe8918f788cbcef88c38da54 upstream. The message size allocated for rtnl ifinfo dumps was limited to a single page. This is not enough for additional interface info available with devices that support SR-IOV and caused a bug in which VF info would not be displayed if more than approximately 40 VFs were created per interface. Implement a new function pointer for the rtnl_register service that will calculate the amount of data required for the ifinfo dump and allocate enough data to satisfy the request.

2014-03-04Fix race between starved list and device removalJames Bottomley
scsi_run_queue() examines all SCSI devices that are present on the starved list. Since scsi_run_queue() unlocks the SCSI host lock a SCSI device can get removed after it has been removed from the starved list and before its queue is run. Protect against that race condition by holding a reference on the queue while running it.

There are two possible reasons to cause AXI bus error 1.Allocate Tile status buffer from virtual memory.

2013-10-23ENGR00278452 PU: fix system hang if run Audio loop testRobin Gong
cpufreq and pu power management will oprate the same register, it looks should keep them operating in order not concurrent. Then use the cpufreq mutex in xPU driver to make sure. Another code bug is in pu power management which base regulator framework, we set the reister directly not regulator, then there is the chance set_volatage will miss the chance if this time voltage setting as the last time setting before PU disable, but we have to do this, so add regulator_sync_voltage to force sync the voltage setting. The drawback is setting twice... Note: This patch is temporary and supposed to be replaced it once we find the root cause. Signed-off-by: Robin Gong <b38343@freescale.com> Acked-by: Jason Liu

This patch adds the re-initialization and the sanity check. Also, add the pointer check for memcpy because the destination may be NULL on UERSPTR mode. Signed-off-by: Robby Cai <R63905@freescale.com>

V4L2_PIX_FMT_YUYV is the original format from camera and the source format for CSI. This format may be needed on Android to do CSC before encoding. We can now choose V4L2_PIX_FMT_YUYV or V4L2_PIX_FMT_UYVY for the CSI output format. Signed-off-by: Robby Cai <R63905@freescale.com>

2013-08-14ENGR00274782 fixed gpu crash when baseAddress is not 0 or 2GXianzhong
The baseAddress of contiguousVidMem is the actual physical address which is not subtracted by gpu baseAddress, but the allocated physical address has been subtracted by gpu baseAddress in gckVIDMEM_Lock, so the invalid offset is produced and used to calculate the logical address.

There's an interim buffer which should only be used when PxP CSC is used. Otherwise the video buffer gets incorrect data by copying the content of interim buffer. The patch fixes this by moving the memcpy to the right place. Signed-off-by: Robby Cai <R63905@freescale.com> (cherry picked from commit 8e0b8ff485dd7cdeabc653f1e27c271ac923710e)
2013-08-08ENGR00273432 DMA: imx-sdma: Allocate 4KB iram page size for bdNicolin Chen
One bd actually needs 4KB page size. So changed the iram_alloc() size parameter to allocate a precise iram memory for bd. This patch also removed the extra iram pool for SDMA due to its insufficient total size: SDMA allows around 48 channels to work simultaneously, so it's better to allocate memory from iram pool directly. [There will be 3KB size waste in sdma->channel_control, which is 640B but actually using 4KB due to 4KB alignment for iram pool.] Acked-by: Huang Shijie <b32955@freescale.com> Signed-off-by: Nicolin Chen <b42378@freescale.com>

The display MIX can be power gated when EPDC, PXP and LCDIF are all inactive. This will save around 1.5mW-1.8mW of power in system IDLE mode. Need to re-initialize the EPDC and PXP whenever the display MIX is powered up as all the register state is lost when the display MIX is power gated.
