2012-03-16ENGR00176567 gpio_keys: Set the IRQF_NO_SUSPEND flag to wakeup buttonXinyu Chen
We should not disabled GPIO irq when doing suspend. During suspend, kernel will call suspend_device_irq() to disable all the irqs (just set a disabled flag, no mask) On the another side, The handle_level_irq will check the irq's disable status to determin it should be handled or unmasked. If the GPIO interrupt happened just after the above suspend_device_irq(), we enters handle_leve_irq(), mask and ack the GPIO irq, then return directly without handle or unmask this irq because of it's disabled. That means the GPIO IMR bit is not set and we can not wake up by the GPIO key button. Signed-off-by: Xinyu Chen <xinyu.chen@freescale.com>
2012-03-16ENGR00175844 irq: enable IRQF_EARLY_RESUME irq when dpm_suspend_noirq failedXinyu Chen
The dpm_suspend_noirq routing calls suspend_device_irqs() first to disable all the irq no matter what flags it has. Then it enumerates the device driver on dpm_suspend_list to call their suspend_noirq pm callback. If any dev suspend failed, it will call dpm_resume_noirq to re-enable all the irq without IRQF_EARLY_RESUME, and return failed. If dpm_suspend_noirq() return failed, then no syscore_resume() can be called, that means the irq with flag IRQF_EARLY_RESUME, can not be re-enabled on this case. error = dpm_suspend_noirq(PMSG_SUSPEND); if (error) { .. goto Platform_finish; } .... error = syscore_suspend(); if (!error) { ... syscore_resume(); } ... dpm_resume_noirq(PMSG_RESUME); Platform_finish: if (suspend_ops->finish) suspend_ops->finish(); So we must enable all the irqs no matter it's IRQF_EARLY_RESUME or not. Otherwise the GPIO power key who's irq has flag of IRQF_EARLY_RESUME will be disabled forever when some device failed to suspend. Signed-off-by: Xinyu Chen <xinyu.chen@freescale.com>
2012-03-16ENGR00175700 System hang when change HDMI from XGA to 1080P with display blankSandor Yu
Change the vide mode from XGA to 1080P when display blank, the system will hang. It is cause by overflow interrupt will trigger when the video mode change, but clean the interrupt status bit depend on pixewl clock. In blank state the pixel clock is gating so the HDMI PHY can't work. Signed-off-by: Sandor Yu <R01008@freescale.com>

2012-03-09ENGR00176159 video: ipuv3-fb: change to timeout semaphore to wait on irq.Zhang Jiejing
change to timeout semaphore to wait on irq. use no timeout semaphore have below issues: 1. since fbmem.c will hold the console_lock() before call PAN_DISPLAY ioictl, if have wrong happens on IPU, IRQ not come, any log printk will not ouput, it will become like a system hang, and developer don't know what's wrong. 2. semaphore don't have timeout, here we can't know irq not come, so hang it infintly. 3. semaphore lock and unlock in different context is a dangous operation. To fix these issue, use timedout version to wait on irq. But for better coding stly to align Kernel Coding Style Doc, better use complete to wait on irq, use semaphre little ugly.

if reset board during suspend, the controller can't success read firmware version, it due to the chip needs some time to wake up, so add 10 ms delay after wakeup chip in probe function. don't need add delay in other code path, since the time was too short to noticed in normal suspend/resume sequency.

issue: if uboot is loaded from eMMC, the eMMC memory will be configured to DDR mode. on kernel startup, it will initialize the card at SDR mode, while the register of USDHC is still configured to DDR enable mode.

2012-02-22ENGR00174734-2 usb: fix bugs that dp and dm are floating at device modePeter Chen
At i.mx6x, the data line (dp and dm) are floating at device mode, that is to say data line will be any values (0-3.6v). So if the usb wakeup is enabled, there will be a wakeup interrupt that causes usb to active mode. In order to fix this problem well, we need to do below things: - Need to discharge both dp and dm - It needs to discharge data line when we switch to device mode and usb cable is disconnected from the host, but not to disable discharge after line state is SE0, the reason is that if we do not pulldown the data line, the line state will be floating again, and possible cause the wakeup interrupt. - It needs to disable discharge data line when the usb cable connects at device mode and usb device is connected at host mode, otherwise it will affect signal quality.
