From: Alan Tull <at...@opensource.altera.com>
Add documentation under drivers/staging for new fpga manager's
sysfs interface.
Signed-off-by: Alan Tull <at...@opensource.altera.com>
---
v5 : (actually second version, but keeping version numbers
aligned with rest of patch series)
Move document to drivers/staging/fpga/Documentation/ABI
v6 : No change in this patch for v6 of the patch set
v7 : No change in this patch for v7 of the patch set
v8 : No change in this patch for v8 of the patch set
v9 : Remove 'firmware' and 'reset' files
Update state strings

+Description: Name of low level fpga manager driver.
+
+What: /sys/class/fpga_manager/<fpga>/state
+Date: July 2015
+KernelVersion: 4.2
+Contact: Alan Tull <at...@opensource.altera.com>
+Description: Read fpga manager state as a string.
+ Valid states may vary by manufacturer; superset is:
+ * unknown = can't determine state
+ * power off = FPGA power is off
+ * power up = FPGA reports power is up
+ * reset = FPGA held in reset state
+ * firmware request = firmware class request in progress
+ * firmware request error = firmware request failed
+ * write init = FPGA being prepared for programming
+ * write init error = Error while preparing FPGA for
+ programming
+ * write = FPGA ready to receive image data
+ * write error = Error while programming
+ * write complete = Doing post programming steps
+ * write complete error = Error while doing post programming
+ * operating = FPGA is programmed and operating
