2017-02-24watchdog: coh901327_wdt: Keep clock enabled after loading driverGuenter Roeck1-20/+1
Enabling the clock before accessing chip registers and disabling it afterwards does not really make sense and only adds complexity to the driver. In addition to that, a comment int the driver suggests that it does not serve a useful purpose either. "The watchdog block is of course always clocked, the clk_enable()/clk_disable() calls are mainly for performing reference counting higher up in the clock hierarchy." Just keep the clock enabled instead. Reviewed-by: Linus Walleij <[email protected]> Signed-off-by: Guenter Roeck <[email protected]>

2017-02-24vxlan: don't allow overwrite of config src addrBrian Russell1-7/+5
When using IPv6 transport and a default dst, a pointer to the configured source address is passed into the route lookup. If no source address is configured, then the value is overwritten. IPv6 route lookup ignores egress ifindex match if the source address is set, so if egress ifindex match is desired, the source address must be passed as any. The overwrite breaks this for subsequent lookups. Avoid this by copying the configured address to an existing stack variable and pass a pointer to that instead.

2017-02-24rtc: ds3232: Call device_init_wakeup before device_registerPhil Reid1-2/+5
The wakealarm attribute is currently not exposed in the sysfs interface as the device has not been set as doing wakealarm when device_register is called. Changing the order of the calls fixes that problem. Interrupts are cleared in check_rtc_status prior to requesting the interrupt. This is only set if an irq is defined. If irq registration fails then set wakeup_capable to false. With this change the sysfs wakealarm attribute will be left visible but it is non functional. rtcwake still returns that the device is not enabled for wakeup.

2017-02-24s390/crypt: Add protected key AES moduleMartin Schwidefsky1-0/+1
This patch introduces a new in-kernel-crypto blockcipher called 'paes' which implements AES with protected keys. The paes blockcipher can be used similar to the aes blockcipher but uses secure key material to derive the working protected key and so offers an encryption implementation where never a clear key value is exposed in memory. The paes module is only available for the s390 platform providing a minimal hardware support of CPACF enabled with at least MSA level 3. Upon module initialization these requirements are checked. Includes additional contribution from Harald Freudenberger. Signed-off-by: Martin Schwidefsky <[email protected]>

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Arnd Bergmann: "In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e. C code changes for SoC platforms. This release cycle the diffstat is quite nice, in that we're removing 3x the amount of code that's being added. The main reason for this is that there's a removal of camera drivers for Freescale i.MX chips (driver was removed so the device registration isn't needed any more). There's also removal of display initialization code for OMAP that is no longer needed. The rest are mostly minor tweaks and cleanups; constification on Samsung platforms, cleanup of ux500 platform data, purge of other unused platform data/device seutp on i.MX and other good stuff.
