+maintainers:
+ - Frank Li <Frank.Li@nxp.com>
+
+description:
+ The Buffer Manager is part of the Data-Path Acceleration Architecture (DPAA).
+ BMan supports hardware allocation and deallocation of buffers belonging to
+ pools originally created by software with configurable depletion thresholds.
+ This binding covers the CCSR space programming model
