2016-04-26mwifiex: add platform specific wakeup interrupt supportXinming Hu4-3/+106
On some arm-based platforms, we need to configure platform specific parameters by device tree node and also define our node as a child node of parent SDIO host controller. This patch parses these parameters from device tree. It includes calibration data dowoload to firmware, wakeup pin configured to firmware, and soc specific wake up gpio, which will be set as wakeup interrupt pin.

2016-04-26rtlwifi: rtl8821ae: Make sure loop counter is signed on all architecturesDavid Müller1-1/+1
The for-loop condition does not work correctly on architectures where "char" is unsigned. Fix it by using an "int", which may also result in more efficient code.

2016-04-26prism54: isl_38xx: Replace 'struct timeval'Tina Ruchandani1-17/+18
'struct timeval' uses a 32-bit seconds field which will overflow in year 2038 and beyond. This patch is part of a larger effort to remove all instances of 'struct timeval' from the kernel and replace them with 64-bit timekeeping variables. The patch also fixes the debug printf specifier to avoid the seconds value being truncated. The patch was build-tested / debugged by removing the "if VERBOSE > SHOW_ERROR_MESSAGES" guards.

This driver relies on driver_info in struct usb_device_id, so allowing adding a device via /sys/bus/usb/drivers/rtl8xxxu/new_id will cause a NULL pointer dereference.
