af3cfdbf56 arm64: kernel: remove ARM64_CPU_SUSPEND config option
ARM64_CPU_SUSPEND config option was introduced to make code providing
context save/restore selectable only on platforms requiring power
management capabilities.

Currently ARM64_CPU_SUSPEND depends on the PM_SLEEP config option which
in turn is set by the SUSPEND config option.

The introduction of CPU_IDLE for arm64 requires that code configured
by ARM64_CPU_SUSPEND (context save/restore) should be compiled in
in order to enable the CPU idle driver to rely on CPU operations
carrying out context save/restore.

The ARM64_CPUIDLE config option (ARM64 generic idle driver) is therefore
forced to select ARM64_CPU_SUSPEND, even if there may be (ie PM_SLEEP)
failed dependencies, which is not a clean way of handling the kernel
configuration option.

For these reasons, this patch removes the ARM64_CPU_SUSPEND config option
and makes the context save/restore dependent on CPU_PM, which is selected
whenever either SUSPEND or CPU_IDLE are configured, cleaning up dependencies
in the process.

This way, code previously configured through ARM64_CPU_SUSPEND is
compiled in whenever a power management subsystem requires it to be
present in the kernel (SUSPEND || CPU_IDLE), which is the behaviour
expected on ARM64 kernels.

The cpu_suspend and cpu_init_idle CPU operations are added only if
CPU_IDLE is selected, since they are CPU_IDLE specific methods and
should be grouped and defined accordingly.

PSCI CPU operations are updated to reflect the introduced changes.

data  to make dm816x boot with basic devices. This finally gets
 dm816x into a usable shape for further work to happen after a few
 years of stalled effort of making this SoC to work with the mainline
 kernel.
 
 As most of the devices are similar to the other omap variants, we
 get at least serial, MMC, Ethernet, I2C, EDMA, pinctrl, SPI and GPMC
 working for these SoCs with the related device tree changes.

c6e3324e3b Allwinner fixes for 3.19
A few minor fixes for the 3.19 kernel:
   - The 8250 uart driver now respects the aliases, which pointed out that we
     were using them wrong. Fixed them.
   - The simplefb pipeline that was used on the A10 caused flickering and
     tearing, and rendered it pretty much useless. Added a new simplefb node
     with another pipeline that removes this issue. Note that we need to keep
     the old node because u-boot 2015.01 uses it.
   - Added a fix for the USB phy node on sun4i/sun5i

3df76a9dcc powerpc/pseries: Fix endian problems with LE migration
RTAS events require arguments be passed in big endian while hypercalls
have their arguments passed in registers and the values should therefore
be in CPU endian.

The "ibm,suspend_me" 'RTAS' call makes a sequence of hypercalls to setup
one true RTAS call. This means that "ibm,suspend_me" is handled
specially in the ppc_rtas() syscall.

The ppc_rtas() syscall has its arguments in big endian and can therefore
pass these arguments directly to the RTAS call. "ibm,suspend_me" is
handled specially from within ppc_rtas() (by calling rtas_ibm_suspend_me())
which has left an endian bug on little endian systems due to the
requirement of hypercalls. The return value from rtas_ibm_suspend_me()
gets returned in cpu endian, and is left unconverted, also a bug on
little endian systems.

rtas_ibm_suspend_me() does not actually make use of the rtas_args that
it is passed. This patch removes the convoluted use of the rtas_args
struct to pass params to rtas_ibm_suspend_me() in favour of passing what
it needs as actual arguments. This patch also ensures the two callers of
rtas_ibm_suspend_me() pass function parameters in cpu endian and in the
case of ppc_rtas(), converts the return value.

migrate_store() (the other caller of rtas_ibm_suspend_me()) is from a
sysfs file which deals with everything in cpu endian so this function
only underwent cleanup.

This patch has been tested with KVM both LE and BE and on PowerVM both
LE and BE. Under QEMU/KVM the migration happens without touching these
code pathes.

For PowerVM there is no obvious regression on BE and the LE code path
now provides the correct parameters to the hypervisor.

3c21b5fa89 ARM: mvebu: armada-xp-synology-ds414: Relicense the device tree under GPLv2+/X11
The current GPL only licensing on the device tree makes it very
impractical for other software components licensed under another
license.

In order to make it easier for them to reuse our device trees,
relicense our device trees under a GPL/X11 dual-license.
