[PATCH 2/2] staging: axis-fifo: remove obsolete text binding

[PATCH 2/2] staging: axis-fifo: remove obsolete text binding

[Raiden Lumine]

The binding is now documented in
Documentation/devicetree/bindings/misc/xlnx,axi-fifo-mm-s.yaml, so the
free-form text version in the driver directory is no longer needed.

-Xilinx AXI-Stream FIFO v4.1 IP core
-
-This IP core has read and write AXI-Stream FIFOs, the contents of which can
-be accessed from the AXI4 memory-mapped interface. This is useful for
-transferring data from a processor into the FPGA fabric. The driver creates
-a character device that can be read/written to with standard
-open/read/write/close.
-
-See Xilinx PG080 document for IP details.
-
-Currently supports only store-forward mode with a 32-bit
-AXI4-Lite interface. DOES NOT support:
-	- cut-through mode
-	- AXI4 (non-lite)

-Required properties:

Staging drivers should be self-contained, please don't move this out of
drivers/staging/ as has been discussed many times in the past.

thanks,
