Subject: [PATCH v2 1/5] soundwire: add static port mapping support
Date: Tue,  9 Mar 2021 14:15:10 +0000	[thread overview]
Message-ID: <20210309141514.24744-2-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20210309141514.24744-1-srinivas.kandagatla@linaro.org>

Some of the SoundWire device ports are statically mapped to Controller
ports during design, however there is no way to expose this information
to the controller. Controllers like Qualcomm ones use this info to setup
static bandwith parameters for those ports.

A generic port allocation is not possible in this cases!
So this patch adds a new member m_port_map to struct sdw_slave to expose
this static map.
