2015-02-06MLK-10227 video: mxsfb: Correct interrupt handlingLiu Ying
We've got a race condition bewteen the interrupt handler mxsfb_irq_handler() and the function mxsfb_wait_for_vsync() on the flag host->wait4vsync. If a CUR_FRAME_DONE interrupt comes and we just finish setting host->wait4vsync to be 1 in mxsfb_wait_for_vsync() before we go to the interrupt handler, we are likely to see the VSYNC_EDGE interrupt status bit asserted in the interrupt handler for the CUR_FRAME_DONE interrupt, disable the not yet enabled VSYNC_EDGE interrupt and finally clear host->wait4vsync. Then, we go back to mxsfb_wait_for_vsync() and enable the VSYNC_EDGE interrupt with host->wait4vsync=0. This may leave the VSYNC_EDGE interrupt enabled all the time and never get a chance to be disabled in the interrupt handler. So, we are deemed to hang up because the uncleared VSYNC_EDGE interrupt status bit will cause the CPU to be trapped forever, according to SoC designer's words. This patch corrects the interrupt handling to handle only the interrupts which are acknowledged by checking both the interrupt enablement bits and the status bits but not the status bits only. This may avoid any bogus interrupt from being handled. Signed-off-by: Liu Ying <Ying.Liu@freescale.com> (cherry picked from commit 24e1e55076b624f9dc93c1f23e14dd024bdff1c7)

System may hang if cpufreq is updated during pu enable/disable flow, add cpufreq mutex in before vddpu regulator enable/disable to make sure no any break happen. Unfortunetly, there is no better way on v3.10 since both PU management and cpufreq are based on regulator framework.

2015-02-02MLK-9769-26 caam: fix RNG buffer cache alignmentSteve Cornelius
The hwrng output buffers (2) are cast inside of a a struct (caam_rng_ctx) allocated in one DMA-tagged region. While the kernel's heap allocator should place the overall struct on a cacheline aligned boundary, the 2 buffers contained within may not necessarily align. Consenquently, the ends of unaligned buffers may not fully flush, and if so, stale data will be left behind, resulting in small repeating patterns. This fix aligns the buffers inside the struct. Note that not all of the data inside caam_rng_ctx necessarily needs to be DMA-tagged, only the buffers themselves require this. However, a fix would incur the expense of error-handling bloat in the case of allocation failure.

2015-02-02crypto: caam - remove duplicated sg copy functionsCristian Stoica
commit 307fd543f3d23f8f56850eca1b27b1be2fe71017 upstream. Replace equivalent (and partially incorrect) scatter-gather functions with ones from crypto-API. The replacement is motivated by page-faults in sg_copy_part triggered by successive calls to crypto_hash_update.

QSPI may failed to alloc enough memory (256MB) for AHB read in previous implementation, especially in 3G/1G memory layout kernel. Dynamically alloc memory to avoid such issue. This implementation generally alloc 4MB memory for AHB read, it should be enough for common scenarios, and the side effect (0.6% performance drop) is minor.

2014-12-24MLK-10057 PxP V4L2 output: force to call pxp_streamoff when device closesRobby Cai
By previous implementation, there's the possibility that last picture remains on screen when the program exits. This can be reproduced by not calling STREAMOFF ioctl in v4l2 output application or just trying to kill the v4l2 output program. The driver has faults to handle this case, since it depends on 'pxp->s0_vbq.streaming' variable be true in close() function to call pxp_streamoff() while the variable is set to 0 after the application calls munmap(). The driver should call pxp_streamoff() even if the application does not call STREAMOFF ioctl. This patch uses the local 'streaming' variable to track the streaming status to fix this problem.

2014-12-19MLK-9986-5 spi: spi-imx: decrease tx fifo wartermark levelRobin Gong
We set both wartermark of txfifo and rxfifo 32 as half of fifo length 64. That will cause easy rxfifo overflow: If there is 31 bytes in rxfifo, rx script will wait the next dma request (the 32th data come into the rxfifo) and schedule out to tx script. Once tx script start to run, the rx script need to wait tx script finish even if its priority higher than tx. Meanwhile, spi slave device may input data continous, plus the rx data which triggered by new tx script(32 bytes). That will quickly consume whole 64 bytes fifo, so we keep 16bytes availbale even in the worst case new tx script triggered during two rx transfer. That may slow down tx slightly, but better than overflow and RX DMA timeout. Signed-off-by: Robin Gong <b38343@freescale.com> (cherry picked from commit 16043ad0ad96aa04a90614e473aa17980af4b8af)

2014-12-19spi: Fix mapping from vmalloc-ed buffer to scatter listCharles Keepax
We can only use page_address on memory that has been mapped using kmap, when the buffer passed to the SPI has been allocated by vmalloc the page has not necessarily been mapped through kmap. This means sometimes page_address will return NULL causing the pointer we pass to sg_set_buf to be invalid. As we only call page_address so that we can pass a virtual address to sg_set_buf which will then immediately call virt_to_page on it, fix this by calling sg_set_page directly rather then relying on the sg_set_buf helper.

2014-12-17MLK-9987: Input: imx_keypad: Fix suspend/resume while keypad is pressedFabio Estevam
Since commit commit 560a64749d1dd0ff ("ENGR00318936-2 input: keyboard: imx: remove usless release interrupt enabled) the following problem happens: - Keep any keypad key pressed - Enter low power mode via "echo mem > /sys/power/state" - Then we are no longer able to wake-up the system via the keypad The reason for this behaviour is that the KRIE (Release Interrupt) is not enabled. In order to fix this problem, we should enable KRIE when a key is pressed (KPKD bit is set) or enable KDIE when no key is pressed (KPKR is set). This way we will always have a valid source of keypad interrupt no matter if the system entered low power mode while a keypad key was pressed or not.

1. Watermark level in sdma use byte as its unit. but asrc driver use word, there is mismatch between them. Here fix this issue and sdma can work more efficiency. 2. Enlarge the larst_period_size, when use small size, for some case, the dma task will timeout, because sdma has no much data for output. Signed-off-by: Shengjiu Wang <shengjiu.wang@freescale.com>
2014-12-11MLK-9970: CSI: VADC image corruptedSandor Yu
If vadc unit test abnormal exit, such as kill -9 pid, next time run the unit test the image corrupted. In original implement, restore VADC specific register code in streamoff function. In specifical case, vadc unit test abnormal exit, the code in streamoff function will been executed in the next run. It is called from VIDIOC_REQBUFS. So csi will lose vadc configuration, and image is corrupted. Move restore VADC specific register code from streamoff function to device close function. Issue resolved.

2014-12-09MLK-9917 imx6sx: fix csi modules prevent system entering low power modeRobby Cai
The reproduce step: $ echo 8 > /proc/sys/kernel/printk $ echo 1 > /sys/class/graphics/fb0/blank $ ifconfig eth0 down $ ifconfig eth1 down $ cat /sys/kernel/debug/clk/osc/pll2_bus/pll2_pfd2_396m/periph2_pre/periph2/mmdc_podf/clk_rate 396000000 The expected result should be '24000000' and following message. Bus freq set to 24000000 start... Bus freq set to 24000000 done! This patch did the following to fix it. - Move the pm runtime handling into csi v4l2 driver, request high bus frequency when the device opens and release high bus frequency when device closes. - Add new api csisw_reset() to mainly do DMA reflash otherwise potentially meet garbage data when CSI starts to work on imx6sl.
