Subject: [PATCH 5/8] typec: mux: Introduce indirection
Date: Mon, 27 Dec 2021 21:21:13 -0800	[thread overview]
Message-ID: <20211228052116.1748443-6-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20211228052116.1748443-1-bjorn.andersson@linaro.org>

Rather than directly exposing the implementation's representation of the
typec muxes to the controller/clients, introduce an indirection object.

This enables the introduction of turning this relationship into a
one-to-many in the following patch.

Subject: [PATCH 5/8] typec: mux: Introduce indirection
Date: Mon, 27 Dec 2021 21:21:13 -0800	[thread overview]
Message-ID: <20211228052116.1748443-6-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20211228052116.1748443-1-bjorn.andersson@linaro.org>

Rather than directly exposing the implementation's representation of the
typec muxes to the controller/clients, introduce an indirection object.

This enables the introduction of turning this relationship into a
one-to-many in the following patch.
