Subject: [PATCH 5/7] Documentation: DT: net: cpsw: allow to specify descriptors pool size
Date: Thu, 1 Dec 2016 17:34:30 -0600 [thread overview]
Message-ID: <20161201233432.6182-6-grygorii.strashko@ti.com> (raw)
In-Reply-To: <20161201233432.6182-1-grygorii.strashko@ti.com>
Add optional property "descs_pool_size" to specify buffer descriptor's
pool size. The "descs_pool_size" should define total number of CPDMA
CPPI descriptors to be used for both ingress/egress packets
processing. If not specified - the default value 256 will be used
which will allow to place descriptor's pool into the internal CPPI
RAM on most of TI SoC.
