Subject: [PATCH v8 6/9] PCI: dwc: Define maximum number of vectors
Date: Fri, 27 Apr 2018 13:00:01 +0100	[thread overview]
Message-ID: <66e6e2a103c576a9e7f65a416b452e9c3e782de3.1524829928.git.gustavo.pimentel@synopsys.com> (raw)

In-Reply-To: <cover.1524829928.git.gustavo.pimentel@synopsys.com>

Add a callback to define the maximum number of vectors used by the RC.

Since this is a parameter associated to each SoC IP setting, makes sense
to be configurable and easily visible to future modifications.

Set DesignWare driver vectors number maximum to 256.
