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.

Enable USB as wakeup source if it is imx6sx and the usb device is connected. We do this tricky thing for disable megafix off, since megafix control code depends on wakeup source. If the usb device is connected, we want the connection is not broken, and to support HSIC device since HSIC controller does not support hot plug. It will not produce un-intended usb wakeup since the usb wakeup is controlled by WIE bit in usb ctrl register, it is only enabled through /sys entry.

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)

Add new ecspi tx script to check the rxfifo status, if it is near to full(>=48 bytes), do not copy data to txfifo which will trigger data push into rxfifo.

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.

2014-12-10MLK-9976: ARM: dts: NAND BBT inconsistency causes UBIFS randomly mount failedAllen Xu
NAND scans the bad blocks during kernel boots up, which invokes the gpmi_ecc_read_oob function to check the badblock mark for each block. In this function the oob data was raw read from NAND chip without ECC, so it hardly to guarantee the consistency of the data considering the possible bitflips. It found that in some MLC NAND the oob data changed and consequently the BBT changed in different power cycles. This issue may cause the UBIFS mount failed. To fix this issue, add "nand_on_flash_bbt" option in dts to store the BBT in NAND flash. On the first time kernel boot up, all bad blocks and probably some fake bad block would be recognized and be recorded in on-nand bad block table. From the second time boot, kernel will read BBT from NAND Flash rather than calling gpmi_ecc_read_oob function to check bad block. No bad block would be missed when create BBT since the probability that 16bit bad block mark filps from 0x00 to 0xFF is extremely low.

2014-12-01MLK-9939 ARM: dts: Add ddrsmp parameter to device tree for i.MX6SX ARM2 boardAllen Xu
The ddr sample point is board related, so add ddrsmp parameter to device tree for i.MX6SX 17x17 ARM2 board. DDRSMP value: 2 ---- i.MX6SX 17x17 ARM2 board Signed-off-by: Allen Xu <b45815@freescale.com> (cherry picked from commit c5d9eb443cda0c4d6e5705a2b51904f49b4f8297)
2014-12-01MLK-9924 mtd: qspi: QSPI1 cannot wake up WAIT mode workaroundAllen Xu
QSPI1 cannot wake up CCM from WAIT mode on SX ARD board, add pmqos to let CCM NOT enter WAIT mode when accessing QSPI1, refer to TKT245618. Signed-off-by: Allen Xu <b45815@freescale.com> (cherry picked from commit feb3b71bffc8afd440c0b972334f2479ebfefa1d)
2014-12-01MLK-9920 mtd: qspi: Add ddrsmp parameter to device treeYe.Li
Since QSPI internal DDR sample point is relevant with board layout, we can't use same value for all boards. Add ddrsmp parameter to device tree for i.MX6SX Sabreauto/Sabresd board. DDRSMP value: 0 ---- i.MX6SX Sabresd board (RevB and RevA) 2 ---- i.MX6SX Sabreauto board The Sabresd RevA board also needs to reduce clock to 29Mhz according to the Spansion spec.
