2014-04-25ENGR00310498 usb: chipidea: otg: fix otg role switch from host to device failureLi Jun
This patch fix the failure when OTG port switch from host to device mode after removes ID cable with usb device(e.g usb hub) connected. How to reproduce: - Enable console wakeup: echo enabled > /sys/class/tty/ttymxc0/power/wakeup - Connect a usb hub with ID cable to OTG port. - Suspend the system: ehco mem > /sys/power/state - Wakeup the system by console. - Remove ID cable together with usb hub. - OTG port cannot switch to device role. Root cause: In this case, ID change interrupt generates before port change interrupt, so with irq disabled, ci_handle_id_switch() will find there is usb device still connected and wait it to disconnect by sleep, but disconnect will not happen since usb irq still disabled so port change irq has no chance to be handled. How this patch is fixing this issue: This patch enables irq before sleep and disables irq after, thus port change irq can be handled and usb device disconnection can timely happen, then ci_handle_id_switch() can stop host and switch to device role correctly. meanwhile change the delay time to 10~15 ms to avoid too frequent connection check and irq enable/disable.

2014-04-24ENGR00301281 media: mxc vout: set input resolution back after PP check/processLiu Ying
In VDOA PP mode, the input resolution would be changed to be VDOA's output for PP to use as its input resolution to go on to do resizing or color space conversion. The input resolution will be different from the original one when VDOA input cropping is enabled. And, this finally causes a wrong input resolution being used if the users do rotation by calling the S_CTRL ioctrl in runtime. In order to fix this issue, this patch sets the original input resolution back after PP task check and process. The issue can be reproduced by the following command line(enable VDOA mode in the gst plugin configuration file first): gplay AVC_MP30_854x356_23.976_679_AACLC_44.1_96_2_TRON_LEGACY.flv (Enter 't 90' to change to rotate 90 degrees in runtime.) In this case, VDOA input cropping(854x356 -> 848x352) is enabled because VDOA input resolution should align to macro block size.

commit 224aa3ed45c8735ae02bb2ecca002409fa6aa772 upstream. Vybrids PIT register is monitonic decreasing. However, sched_clock reading needs to be monitonic increasing. Use bitwise not to get the complement of the clock register. This fixes the clock going backward. Also, the clock now starts at 0 since we load the register with the maximum value at start.

2014-04-18ENGR00309045 net: fec_ptp: fix timestamp errors when do stress testFugang Duan
"FSL_stressPTP" tool is supposed to test the capability characteristics of a ptp stack porting. The stresstest shall measure the overall load of the stack under test by sending delay request and signalling messages.The higher the overall load on the stack is, the higher your packet loss will be. The patch fix the timestamp error in high overall load stress test like: ./FSL_stressPTP -u -b 10.192.242.10 -d 10.192.242.6 -e eth0 -m 00:01:02:04:04:19 -i 100 -t 10 -f -6 -s -6 -c 10 And enet interrupt coalescing feature introduce ptp packet latency, which may cause that the timestamp don't store the related timestamp buffer when stack use ioctl interface to access the message. So add some 4ms delay after getting timestamp fail to let the next looking up success. Suggest to disable interrupt coalescing feature by ethtool when run 1588 cases.

2014-04-18ENGR00308397 video: mxsfb: unblank fb explicitly in probe()Liu Ying
The following two commits for backlight core driver introduce an usecount for each backlight device and on/off usage info of each framebuffer associated with it so that we may enable/disable a backlight device when necessary. commit dcb7e61054b959dc4d601a96cce5cc85ad1568ef commit b48b097319587422195adc3f8b2b3b0c067943cc The problem is that some framebuffer drivers would enable their display controllers in probe() and some backlight device drivers would enable their backlights in probe() so that the backlight device usecounts and the on/off usage info of framebuffers are out of counting at the probing stage. This causes a backlight cannot be disabled by blanking the relevant framebuffer(s) before any fb unblanking operation, though it's quite reasonable for the userland to unblank the framebuffer(s) before using it. In order to avoid the potential unnecessary lighten backlight left behind for the mxsfb driver, this patch unblanks framebuffer explicitly in probe() since the LCDIF display controller is actually enabled there.

2014-04-16usb: phy: make PHY driver selection possible by controller driversRoger Quadros
Convert PHY Drivers from menuconfig to menu so that the PHY drivers can be explicitely selected by the controller drivers. USB_PHY is no longer a user visible option. It is upto to the PHY drivers to select it if needed. This patch does so for the existing PHY drivers that use the USB_PHY library. Doing so moves the USB_PHY and PHY driver selection problem from the end user to the PHY and controller driver developer. e.g. Earlier, a controller driver (e.g. EHCI_OMAP) that needs to select a PHY driver (e.g. NOP_PHY) couldn't do so because the PHY driver depended on USB_PHY. Making the controller driver depend on USB_PHY has a negative effect i.e. it becomes invisible to the user till USB_PHY is enabled. Most end users will not familiar with this. With this patch, the end user just needs to select the controller driver needed for his/her platform without worrying about which PHY driver to select. Also update USB_EHCI_MSM, USB_LPC32XX and USB_OMAP to not depend on USB_PHY any more. They can safely select the necessary PHY drivers. [ balbi@ti.com : refreshed on top of my next branch.
