2013-01-21ENGR00240740-3 IPUv3 fb:Workaround bootup ipu errorLiu Ying
Enabling IPU hsp clock in mxcfb_probe() context by calling ipu_init_channel() can avoid the IPU display channel(setup in bootloader) from being damaged by some IPU common driver APIS which enable/disable IPU hsp clock when doing driver probe. However, somehow, after LDO bypass patch set is pushed to kernel, this clock enablement can trigger IPU errors (IPU_INT_STAT_5 - 0x00800000/IPU_INT_STAT_10 - 0x00100000) and a display flash. A workaround is to enable IPU hsp clock when we are at ipu_probe() context, which is earlier than mxcfb_probe() context, and then to disable(cleanup) the clock once more when fb_set_par() is triggered by the user for the first time. This patch updates the comment for ipu_init_channel() and ipu_enable_channel() in mxcfb_probe() context, and disables ipu hsp clock when fb_set_par() is triggered by the user for the first time.

2013-01-17ENGR00240506 fix a bug in abnormal abort handlingHongzhang Yang
Bug: If app quits before FW is loaded to VPU, VPU driver will hang in vpu_release(). Root cause: In that case, if BIT_BUSY_FLAG=1, vpu_release may reset VPU and run FW init code, but FW has not been loaded. Solution: - Don't run FW init code after reset since VPU lib can load it next time. - If PC=0, which means VPU never runs, don't check BIT_BUSY_FLAG Signed-off-by: Hongzhang Yang <Hongzhang.Yang@freescale.com>

The clock should be turn off when gadget class driver unregister. - There is an abnormal usb wakeup interrupt happen if phy is no power without VBUS.

2013-01-09ENGR00237682-3: mxc_v4l2_capture: ov5640: support scaling modesSheng Nan
The method for change between scaling and subsampling mode is different from ov5640_mipi. (image bigger than 1280*960 is scaling mode, smaller is subsampling). According to OV5640 Auto Focus Camera Module Application Notes (with DVP Interface) R2.14.pdf, change back from QSXGA to VGA, don't need to do exposure calculation. According to the test result, if we do exposure calculation when change back from scaling to subsampling mode, the image would be dark. So the method is: Change to scaling mode, go through exposure calcuation. Change to or back to subsampling mode, change mode directly. Supported mode: - QSXGA@7.5fps - 1080P@7.5fps Can't make 1080P works at 15fps. Here is a reply from ov fae: because of scaling down, max frame for 1080P is the same as 5M, both are 15fps. so if 5M can runs up to 7.5fps on your demo, then 1080P is the same 7.5fps max.

2013-01-06ENGR00238237-1 mx6sl: csi/v4l: fix camera picture flickering issueRobby Cai
Flickering issue happens when there's no buffer to be processed(e.g., the pace of QBUF is much slower than DQBUF). The cause is the hardware is using double buffering, while the driver has no good protection at above case and thus the CSI will fill the buffer not in the right order. The way to fix is refining the output of the working_q buffer list, that is, if there's no buffer to be processed then output to a dummy buffer. Another important change is to only do DMA reflash operation when SOF is detected in streamon. Remove this operation is CSI interrupt handler because it violates to the SPEC (only do DMA reflash before DMA is enabled but NOT at the time or after DMA's enabled).

2012-12-13ENGR00236879 Enhance VPU driver to handle API call sequence abnormal abortHongzhang Yang
Some application may exit without calling neccessay API to wrap up VPU after it receives error message. This could lead to system hang because driver will power off VPU (vpu_release) while VPU may still be busy. We require application to strictly follow the API call sequence even in error handling case. Meanwhile, we enhance VPU driver to protect against such abnormal abort, to prevent system hang at least. If the last instance is closed, VPU will gate off or power off only if VPU is idle. Signed-off-by: Hongzhang Yang <Hongzhang.Yang@freescale.com>

If do dma reflash operation when dma is enabled, the system will hang and we can not connect to the core through jtag.
