2013-08-08ENGR00274493 mx6sl: csi/v4l: Fix capture incorrect data with format UYVYrel_imx_3.0.35_4.1.0_rc2Robby Cai
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>

2013-07-25ENGR00270573-2 [MX6SL]Add support for dynamic Power Gating of the display MIXRanjani Vaidyanathan
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.

2013-07-19ENGR00271566 usb: otg: comment otg_statemachine which we do not needPeter Chen
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. Besides, it causes one kernel dump at Sabreauto board due to it calls gpio API at spin lock, but at Sabreauto board the USB power GPIO is expanded by MAX7310 which calls i2c read/write and will schedule itself.

2013-07-15ENGR00270802 usb: otg: delete redundant vbus off operationPeter Chen
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. The solution is to remove the call of fsl_otg_drv_vbus() in fsl_otg_start_host(). Signed-off-by: Peter Chen <peter.chen@freescale.com>
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.
