This is the 4th submission of Intel Stratix10 remote system update (RSU)
driver.
Intel Stratix10 remote system update driver patches have been reviewed by
Alan Tull and other colleagues at Intel.
The Intel Stratix10 Remote System Update driver exposes interfaces
access through the Intel Stratix10 Service Layer to user space via sysfs
interface. The RSU interfaces report and control some of the optional RSU
features on Intel Stratix 10 SoC.
The RSU feature provides a way for customers to update the boot
configuration of a Intel Stratix 10 SoC device with significantly reduced
risk of corrupting the bitstream storage and bricking the system.
v4: removed devm_device_add_groups() & devm_device_remove_groups(), then
utilized groups at struct device_driver
replaced /sys/devices/platform/stratix10-rsu.0/ with /sys/devices/.../
stratix10-rsu.0/driver/
removed spaces
v3: changed kernel version from 5.2 to 5.3 in RSU sysfs interface document
v2: removed compatible = "intel,stratix10-rsu"
added intel stratix10 RSU device
changed to support RSU in handling watchdog timeout
s/attr_group/ATTRIBUTE_GROUPS, use devm_device_add_groups() and
devm_device_remove_groups()
added check the return value from rsu_send_msg()
removed RSU binding text file
other corrections/change
