2013-08-27ENGR00275429 Recovery: Screen flashing found when wipe data in recovery modeguoyin.chen
Android Recovery UI framework uses FBIOPUT_VSCREENINFO with yoffset update to update display. Both elcdif and ipuv3 FB will set var.activate to be FB_ACTIVATE_FORCE in driver's probe. User space will get the VSCREENINFO with activate been set to FB_ACTIVE_FORCE. Each FBIOPUT_VSCREENINFO with only yoffset update will make the driver reinit.The activate should be cleared once set_par() been finished. HDMI driver should only reinit hdmi only when the mode changed. fbmem will broadcast MODE_CHANGE for each FBIOPUT_VSCREENINFO ioctl even it only have yoffset update.

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>

We have not implemented fully OTG support, so we can't call otg_statemachine since the state machine may incorrect at current dual-role switch design. At existed code, it will call otg_statemachine, in fact, it doesn't need.

The problem locates at: fsl_otg_start_host(fsm, 0); if (pdata->wake_up_enable) pdata->wake_up_enable(pdata, false); otg_drv_vbus(fsm, 0); fsl_otg_start_host(fsm, 0) internally calls fsl_otg_drv_vbus(), which does the same thing as otg_drv_vbus(fsm, 0). More critically, we need disable VBUS wakeup before close VBUS operation, otherwise unexpected VBUS wakeup will occur.

2013-07-15ENGR00269468 IPUv3 dev:Silence an annoying warning messageLiu Ying
We call the function ipu_calc_stripes_sizes() to calculate stripe settings for vdi split mode. Chances are that the parameters output_frame_width and maximal_stripe_width for the function satisfy the relationship 'output_frame_width <= maximal_stripe_width' and make the function return non-zero value. This causes the IPU device driver generates an annoying warning message, though the default stripe settings still can work. This patch simply silences the warning message by reducing the print log level from error to debug.

2013-07-12ENGR00269619 mxc vout:improve vb handling for 3 field deinterlacingLiu Ying
We need 2 video buffers to get a deinterlaced frame in VDI low motion mode or medium motion mode. When there is no enough video buffer in the active list, no one triggers the video buffer timer, then users may be blocked at dqueue buffer ioctrl if they are in blocking mode. In order to fix this issue, we may peek the first available video buffer in the queue list so that the buffer may be taken as a reference video buffer to do deinterlacing. If there is no video buffer in the queue list, we should make users be able to trigger the timer again when they queue buffers to the driver.

2013-07-10ENGR00255920-2 mxc vout:wait for 2 vsyncs when streamoffLiu Ying
Some expiring video buffers may have been rendered to display triple buffers for display. The relevant triple buffers are set to be ready and depend on the display hardware engine to switch them to be active on screen in turn automatically. So, we need to wait for at least 2 vsyncs to make sure all of the expiring video buffers be shown on display already.

2013-07-10ENGR00255920-1 mxc vout:Remove cancel_work_sync() when streamoffLiu Ying
We hope the queued works can be done before streamoff, since the works will render expiring video buffers to display. But, the function cancel_work_sync() cannot guarantee this. Instead, it may cancel some queued works before they starts to work. This patch removes the function call cancel_work_sync() when streamoff. We rely on the function flush_workqueue() right after it to make sure queued works be done before streamoff.

2013-07-09ENGR00270045: thermal: Add timeout for temperature updateAnson Huang
Need to add timeout for temperature update, otherwise, if suspend comes during thermal sensor measurement, its power will be turned off, and after resume, the delay work thread will never get finish flag and result in thread forever loop, temperature will never get updated. And if we wait for the measurement finish before suspend, the time is too long for suspend, as one single measurement would take as long as 100ms which is not good for suspend, so just add a timeout.
