755a739794 dt-bindings: firmware: imx: Move system control into dt-binding headfile 
i.MX8 SoCs DTS file needs system control macro definitions, so move them
into dt-binding headfile, then include/linux/firmware/imx/types.h can be
removed and those drivers using it should be changed accordingly.

b720aaa347 firmware: tf: Different way of L2 cache enabling after LP2 suspend 
ASUS TF300T device may not work properly if firmware is asked to fully
re-initialize L2 cache after resume from LP2 suspend. The downstream
kernel of TF300T uses different opcode to enable cache after resuming
from LP2, this opcode also works fine on Nexus 7 and Ouya devices.
Supposedly, this may be needed by an older firmware versions.

a2cc220a9a firmware: xilinx: Add sysfs and API to set boot health status 
Add sysfs interface to set boot health status from user space.
Add API used by this interface to communicate with firmware.

If PMUFW is compiled with CHECK_HEALTHY_BOOT, it will check the
healthy bit on FPD WDT expiration. If healthy bit is set by a user
application running in Linux, PMUFW will do APU only restart. If
healthy bit is not set during FPD WDT expiration, PMUFW will do
system restart.

b3ae24c448 firmware: xilinx: Add sysfs to set shutdown scope 
The Linux shutdown functionality implemented via PSCI system_off does
not include an option to set a scope, i.e. which parts of the system to
shut down.

This patch creates sysfs that allows to set the shutdown scope for the
next shutdown request. When the next shutdown is performed, the platform
specific portion of PSCI-system_off can use the chosen shutdown scope.
