Subject: [PATCH v4 07/10] PCI: dwc: Define maximum number of vectors
Date: Mon, 16 Apr 2018 15:37:55 +0100	[thread overview]
Message-ID: <34c83824e58f152aacbfe98c41ab44ec44eec96c.1523881182.git.gustavo.pimentel@synopsys.com> (raw)
In-Reply-To: <cover.1523881182.git.gustavo.pimentel@synopsys.com>
In-Reply-To: <cover.1523881182.git.gustavo.pimentel@synopsys.com>

Adds a callback that defines the maximum number of vectors that can be use
by the Root Complex.

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

The designware IP supports a maximum of 256 vectors.
