Do not switch the mem view when the imx pcie ep/rc validation system is enabled. Otherwise, the RC wouldn't access the mem of the ep device in the imx pcie ep/rc validation system.

2015-03-16MLK-10423: Capture: System hang if capture test app been killedSandor Yu
System will hang if csi unit test mx6s_v4l2_capture.out process been killed. In csi capture driver function mx6s_csi_enable/disable is called by vidioc_streamon/streamoff function. But when csi unit test process is killed, vidioc_streamon/streamoff will not been called, and csi function still working even the csi clock is gated. Move mx6s_csi_enable/disable function from mx6s_vidioc_streamon/streamoff function to mx6s_start_streaming/ mx6s_stop_streaming function to resolve the issue.

when uninstalling ath6kl_sdio after iperf test. When handing the command "ifconfig wlan0 down", the driver handler did not notify the disconnected event to the upper layer stack cfg80211, which would cause the relating resources unable to be released. A notification of disconnet event to cfg80211 was added when the driver was changed to the disconnect state.

2015-03-06MLK-10211 can: flexcan: fix resume failed issueDong Aisheng
We can observe the following error during system resume. dpm_run_callback(): platform_pm_resume+0x0/0x4c returns -110 PM: Device 2090000.can failed to resume: error -110 It is caused by the flexcan is in disable state and the clock is disabled by default while the CAN is not up. During resume, the calling of flexcan_chip_enable will obviously fail due to no clock. The issue only happened when CAN device is not up. If CAN is up, clock is there and no issue will happen. Because the CAN is always in disabled state by default if it's not up. We don't have to disable it again during suspend and enable it after resume. This patch simply the suspend/resume to only enter/exit disabled mode if CAN is up.

than 396MHz for i.MX6SX, according to the latest datasheet, added a 198MHz setpoint in cpufreq driver. The 198MHz setpoint is NOT enough to support playing mp3,the system will stay at a higher setpoint and high_bus_mode. So when having a setpoint lower than 396MHz, make sure when the cpufreq is at 396MHz or lower, the busfreq is always in low_bus_mode to save more power. Signed-off-by: Bai Ping <b51503@freescale.com>

2015-02-15MLK-10248 video: ipuv3-fb: fix hang up with cmdline option for CLAA WVGARobby Cai
The kernel boot stops at "Starting kernel ..." if assign cmdline "video=mxcfb0:dev=lcd,if=RGB565". The cause is that there's no 'mode_str' property for mxcfb0 in DTS file, so of_property_read_string() does not touch it and 'mode_str' could be used uninitialized in mxcfb_get_of_property(), where it's assigned to plat_data->mode_str and then used uninitialized in fb_find_mode(). This may cause buffer overflow. This patch initializes 'mode_str' to NULL to fix it.

To maintain scalability let's add common methods to attach and detach a PM domain for a device, dev_pm_domain_attach|detach(). Typically dev_pm_domain_attach() shall be invoked from subsystem level code at the probe phase to try to attach a device to its PM domain. The reversed actions may be done a the remove phase and then by invoking dev_pm_domain_detach(). When attachment succeeds, the attach function should assign its corresponding detach function to a new ->detach() callback added in the struct dev_pm_domain.

2015-02-11PM / Domains: Add generic OF-based PM domain look-upTomasz Figa
This patch introduces generic code to perform PM domain look-up using device tree and automatically bind devices to their PM domains. Generic device tree bindings are introduced to specify PM domains of devices in their device tree nodes. Backwards compatibility with legacy Samsung-specific PM domain bindings is provided, but for now the new code is not compiled when CONFIG_ARCH_EXYNOS is selected to avoid collision with legacy code. This will change as soon as the Exynos PM domain code gets converted to use the generic framework in further patch. This patch was originally submitted by Tomasz Figa when he was employed by Samsung.

2015-02-09MLK-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)

Add hwrng support for i.MX6SL. 1. Add RNG driver. This driver originated as fsl-rngc.c. It has been modified to support device tree. The name has been changed since it supports both b and c variants of RNG. 2. Added clock and compatible info to the device tree data. 3. Added the entry in the options in the Kconfig for hwrng.

2015-01-28ENGR00325832 usb: chipidea: usb vbus glitch check logic changeLi Jun
This patch changes the vbus glitch check to cover usb otg certification case, so the possible cases of vbus rise: - USB vbus can reach AVV(4.4v), valid vbus. - USB vbus keeps above BSV(0.8v) but lower than AVV(4.4v) for more than 300ms, we think it's valid vbus event, this can meet usb otg certificataion case(B device can do connection in 1s when vbus is 4.0v). - USB vbus cannot be kept above BSV(0.8v) for more than 300ms, it's a vbus glitch. In case of vbus drop: if the vbus on flag is not set, it's a vbus glitch, otherwise it's a valid vbus drop event.
