2013-08-15ENGR00275391 i.mx6d/q: disable the double linefill feature of PL310Jason Liu
The L2 cache controller(PL310) version on the i.MX6D/Q is r3p1-50rel0 The L2 cache controller(PL310) version on the i.MX6DL/SOLO/SL is r3p2 But according to ARM PL310 errata: 752271 ID: 752271: Double linefill feature can cause data corruption Fault Status: Present in: r3p0, r3p1, r3p1-50rel0. Fixed in r3p2 Workaround: The only workaround to this erratum is to disable the double linefill feature. This is the default behavior. [in the commit:c483abdca0011c1342bad42f16925dd5a2c7c091] ENGR00271977-1 imx6_defconfig: enable PL310_ERRATA_769419 There is one error in the commit log, the correct PL310 version in i.MX6DL/SOLO should be r3p2, not r3p1-50rel0. so, PL310_ERRATA_769419, will not apply to i.MX6DL/SOLO. But since we build one image to support both i.MX6Q and i.MX6DL/SOLO, the ideal solution is to manage this errata in dynamic way. Someone did post the patches here: http://lists.infradead.org/pipermail/linux-arm-kernel/2013-January/145593.html As the discussion on the above link, Russell King, the ARM arch maintainer said: "As I already said, there is _no_ point making the barrier conditional; it's probably more expensive to make it conditional than just to execute it every time. But we still might as well optimize it away if we are running _only_ on platforms which _do_ _not_ have that errata." So, we will turn on the PL310_ERRATA_769419 on both i.MX6D/Q and i.MX6DL/SOLO.

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>

2013-07-25ENGR00272022 msl-mx6: usb: wait PHY clock stable explicitlyPeter Chen
At mx6, if usb wakeup is not enabled, the PHY's power will be off during the system suspend, so the dp/dm will be unknown after the system resumes, it may wake up controller at some boards since dp/dm's status satisfies wake up condition. If the controller is waken up, the PHCD will be cleared automatically. According to IC requirement, after PHCD is cleared, we need to wait 1ms before clear PHY's clock gate to wait PHY's clock stable. At above condition, the PHCD is cleared automatically, it may less than 1ms before we clear PHY's clock gate, then, software operation to clear PHY's clock gate will be useless. At this case, the PHY will works abnormal, and cause the controller hang when we write some registers (eg, portsc). Signed-off-by: Peter Chen <peter.chen@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.

This patch is copied from commit 25b7679136fd85b1e5197e36a0ca126163e89590 Just unable to cherry-pick due to different file names. The ASoC core tries to not enforce symmetric rates when two streams open simultaneously. It does so by checking rtd->rate being zero. This works exactly once after booting because it is not set to zero again when the streams close. Fix this by setting rtd->rate when no active stream is left.

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.

Board files correctly define fec gpio irq to wake up wait mode since FEC interrupt cannot connect to GPC, otherwise board files define fec gpio irq to -1.

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.
