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. 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.

When HDMI cable plugin, the frame buffer driver will print error message "can't do pan display when fb is blank", it is cause by sii902x driver call fb_set_var after fb power down. sii902x driver should not mangement fb blank state, it should only care its own power state. Remove fb_blank function and replace it with sii902x power management function. Signed-off-by: Sandor Yu <R01008@freescale.com>
2013-07-02ENGR00261285-02 Lcdif FB: Fix video timing settingSandor Yu
Correct HSYNC_PERIOD, VSYNC_PERIOD, HORIZONTAL_WAIT_CNT and VERTICAL_WAIT_CNT setting. In MX6SL RM, these parmeters define as followed: - HSYNC_PERIOD: Total number of CLK_DIS_LCDIFn cycles between two positive or two negative edges of the HSYNC signal. - VSYNC_PERIOD: Total number of units between two positive or two negative edges of the VSYNC signal. - HORIZONTAL_WAIT_CNT:In the DOTCLK mode, wait for this number of clocks from falling edge (or rising if HSYNC_POL is 1) of HSYNC signal to account for horizontal back porch plus the number of DOTCLKs before the moving picture information begins. - VERTICAL_WAIT_CNT: In the DOTCLK mode, it accounts for the veritcal back porch lines plus the number of horizontal lines before the moving picture begins. After apply the patch, run HDMI CTS with video mode 480p,720p and 1080p test case 7-16~7-19, 7-21~7-27 and 7-33 pass. Signed-off-by: Sandor Yu <R01008@freescale.com>

Allows device MMC boot partitions to be accessed. MMC partitions are treated effectively as separate block devices on the same MMC card. - Boot partition access howto: - To enable write access to /dev/mmcblkXbootY, disable the forced read-only access with: echo 0 > /sys/block/mmcblkXbootY/force_ro To re-enable read-only access: echo 1 > /sys/block/mmcblkXbootY/force_ro - Signed-off-by: Richard Zhu <r65037@freescale.com>

This patch fix the CAAM support for Crypto User Space API support. in the dma_map_sg_chained() function, the chained mode will loop until the scatter list end, but when the scatter list end, it will return null and orignal code will set this to the sg list point used by dma_sync, so it will panic.
