Subject: [PATCH 2/2] dt: bindings: add new dt entries for brcmfmac
Date: Mon, 19 Mar 2018 01:41:01 +0700 [thread overview]
Message-ID: <20180318184101.26951-2-alexey.roslyakov@gmail.com> (raw)
In-Reply-To: <20180318184101.26951-1-alexey.roslyakov@gmail.com>
In case if the host has higher align requirements for SG items, allow
setting device-specific aligns for scatterlist items.
