2012-07-03ENGR00177756 usb-host: quit system suspend after usb remote wakeup occursPeter Chen
If the usb remote wakeup occurs before bus(roothub) suspend, it can stop the system suspend process, the patch adds handle error message process for roothub. If the remote wakeup occurs after bus(roothub) suspend, then the suspend will go on suspending, and usb phy will fail to respond wakeup signal.

- Without host wakeup enable, after doing system suspend/resume, plug in usb cable(both host/device) with no response, the reason is usb wakeup is not enable after suspend resume. - clock refcount will not be 0 after usb enters low power mode,the reason is OTG ID wake up not do recover hcd.

2012-07-03ENGR00176177-2 Add irq count mechanism to interactive governorAnson Huang
Add irq count to CPUFreq as a freq change condition. Because some devices' working mode is unable to issue CPUFreq change because of low CPU loading, but the cpu freq will impact these devices' performace significantly. Interactive govervor will sample the cpu loading as well as the irq count which is registered. If the loading or the irq count exceed the threshold we set, governor will issue an CPUFreq change request. These devices' irq threshold and enable/disable can be modified via /sys/devices/system/cpu/cpufreq/interactive/irq_scaling echo 0xAABBBC to change the default setting as below AA : irq number BBB: threshold C :enable or disable Currently only enable USDHC3, USDHC4, GPU, SATA and USB by default, we can add device to the init struct which is located in arch/arm/mach-mx6/irq.c.

2012-07-03ENGR00177745-1 Add interactive cpufreq governorAnson Huang
cpufreq: interactive: New 'interactive' governor This governor is designed for latency-sensitive workloads, such as interactive user interfaces. The interactive governor aims to be significantly more responsive to ramp CPU quickly up when CPU-intensive activity begins. Existing governors sample CPU load at a particular rate, typically every X ms. This can lead to under-powering UI threads for the period of time during which the user begins interacting with a previously-idle system until the next sample period happens. The 'interactive' governor uses a different approach. Instead of sampling the CPU at a specified rate, the governor will check whether to scale the CPU frequency up soon after coming out of idle. When the CPU comes out of idle, a timer is configured to fire within 1-2 ticks. If the CPU is very busy from exiting idle to when the timer fires then we assume the CPU is underpowered and ramp to MAX speed. If the CPU was not sufficiently busy to immediately ramp to MAX speed, then the governor evaluates the CPU load since the last speed adjustment, choosing the highest value between that longer-term load or the short-term load since idle exit to determine the CPU speed to ramp to. A realtime thread is used for scaling up, giving the remaining tasks the CPU performance benefit, unlike existing governors which are more likely to schedule rampup work to occur after your performance starved tasks have completed. The tuneables for this governor are: /sys/devices/system/cpu/cpufreq/interactive/min_sample_time: The minimum amount of time to spend at the current frequency before ramping down. This is to ensure that the governor has seen enough historic CPU load data to determine the appropriate workload. /sys/devices/system/cpu/cpufreq/interactive/go_maxspeed_load The CPU load at which to ramp to max speed.

2012-07-03ENGR00175884 System resume failed when the power key was pressed shortlyLin Fuzhen
Some platform like Android needs to get the power key event to reume the other devcies such as FB, TS. System resume failed when the gpio power key was pressed shortly sometime, but can resume the by long press the power key. The root cause of this issue is that the GPIO IRQ is registered as device IRQ, but device IRQs will just be enabled after early resume finished, so when the power key press shortly, the gpio-irq may still disabled in that time, and the ISR will be ignored and could not detect the key down event. To fix this bug, add the IRQF_EARLY_RESUME flag to the irq if platform has specified that the button can wake up the system , in this way, this irq will be enabled during syscore resume, so that the power key press can be handled and reported as early as possible.
