[PATCH] extcon: Add documentation for EXTCON_CHG_USB_SLOW/FAST

by Baolin Wang

Currently there are no documentation for EXTCON_CHG_USB_SLOW/FAST charger connector. These names don't mean much and no guide to tell users how to use it, thus try to add documentation to make them clear.

[PATCH] usb: dwc3: gadget: Avoid race between dwc3 interrupt handler and irq thread handler

by Baolin Wang

On some platfroms(like x86 platform), when one core is running the USB gadget irq thread handler by dwc3_thread_interrupt(), meanwhile another core also can respond other interrupts from dwc3 controller and modify the event buffer by dwc3_interrupt() function, that will cause getting the wrong event count in irq thread handler to make the USB function abnormal. We should add spin_lock/unlock() in dwc3_check_event_buf() to avoid this race.

[PATCH] cpufreq: Remove CONFIG_CPU_FREQ_STAT_DETAILS config option

This doesn't have any benefit apart from saving a small amount of memory when it is disabled. The ifdef hackery in the code makes it dirty unnecessarily. Clean it up by removing the Kconfig option completely. Few defconfigs are also updated and CONFIG_CPU_FREQ_STAT_DETAILS is replaced with CONFIG_CPU_FREQ_STAT now in them, as users wanted stats to be enabled.
