2014-08-06ENGR00324668 mmc: core: add delay for SD3.0 UHS mode switchDong Aisheng
We may meet the following errors with a SD3.0 DDR50 cards during reboot test. mmc0: new ultra high speed DDR50 SDHC card at address aaaa mmcblk0: mmc0:aaaa SU08G 7.40 GiB mmcblk0: error -84 transferring data, sector 0, nr 8, cmd response 0x900, card status 0xb00 mmcblk0: retrying using single block read mmcblk0: error -84 transferring data, sector 0, nr 8, cmd response 0x900, card status 0x0 end_request: I/O error, dev mmcblk0, sector 0 ..... Buffer I/O error on device mmcblk0, logical block 0 mmcblk0: unable to read partition table The root cause is still unknown. Since there's an errata of Sandisk eMMC card before that it requires delay for CMD6 for eMMC DDR mode to work stable, we also suspect the SD3.0 DDR requires similar delay. (Still not confirmed by Sandisk) By adding the delay, the overnight reboot test(run 2000+ times) did not show the issue anymore. Originally it can easy show the error after about 20 times of reboot test. So this patch would be the temporary workaround for Sandisk SD3.0 DDR50 mode unstable issue.

2014-08-06ENGR00325494 pcie:delay is requried after clks_enRichard Zhu
- the async reset input need ref clock to sync internally, when the ref clock comes after reset, internal synced reset time is too short , cannot meet the requirement so, ssp_en should be asserted at least 4us after ref clock stable. - align to the community imx pcie driver, add the about 200us delay to make sure that it can allow the pcie clks stabilize, when pcie clks are enabled on imx6q/dl/solo.

Vadc need time to auto standards detection, the default standard is NTSC, if vadc connect to PAL camera and no enough time to detect the video mode, driver will get NTSC mode.

2014-07-11ENGR00322272-2: video: mxc ldb: remove ldb_di_sel from pixel rate setupShawn Guo
Since commit 0bec46131d88 (ENGR00318063-8: ARM: imx6q: hide buggy ldb_di_sel from clk API), the mux clock ldb_di_sel becomes unavailable from the clock tree. The LDB driver sets up its pixel clock rate with the help of ldb_di_sel knowledge, and thus causes problem. The net result is the LDB pixel clock rate slows down to 50 MHz (50285714) from the original 64 MHz (64653061) on imx6q. The patch fixes the problem by removing the ldb_di_sel knowledge from the clock configuration path and just setting the rate on div_sel[chno] clock. The bonus point is that we can use chan.vm.pixelclock directly instead of calculating the required rate we need to set on ldb_di_sel_parent. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Controller needs to be active during system suspend, otherwise the core may run resume when the parent is still at suspend if other driver's suspend fails, it occurs before parent's suspend has not started, but the core suspend has finished. Signed-off-by: Peter Chen <peter.chen@freescale.com>
2014-07-04ENGR00320792-3 usb: gadget: mark init as late_initcallPeter Chen
Since we introduce -EPROBE_DEFER for udc driver, it will be probed at late_initcall if it is defered. When the gadget is built in, it will return "couldn't find an available UDC" at such case. That's the problem we met at below link: http://marc.info/?l=linux-usb&m=137706435611447&w=2 We have no driver's probe at gadget driver, so we can't return -EPROBE_DEFER. And it is also not suitable to defer udc_bind_to_driver if the udc is not found temporarily, since it is hard to decide the return value for usb_gadget_probe_driver. Due to above reasons, mark gadget's init as late_initcall may be a moderate solution. Signed-off-by: Peter Chen <peter.chen@freescale.com>

Before DMA finish, we have to disable flow control, otherwise there have one corner issue like: Flow control enable, RTS always is high while there have no uart terminal connect to imx uart, and then user transmit data by the uart, after some time, TX FIFO is _FULL_, SDMA still don't complete the current transcation, so hold on. There no SDMA interrupt generate, the "dma_wait" event cannot be waked up. Signed-off-by: Fugang Duan <B38611@freescale.com>
