Subject: [PATCH 03/12] wil6210: support loading dedicated image for sparrow-plus devices
Date: Wed, 11 Jan 2017 18:12:39 +0200	[thread overview]
Message-ID: <1484151168-894-4-git-send-email-qca_merez@qca.qualcomm.com> (raw)
In-Reply-To: <1484151168-894-1-git-send-email-qca_merez@qca.qualcomm.com>

From: Lazar Alexei <qca_ailizaro@qca.qualcomm.com>

Driver may be used in platforms where some use sparrow cards while
other use sparrow-plus cards, where different FW image is needed.
Add the capability to load dedicated FW image in case sparrow-plus
card is detected and fallback to default image if such does not exist.
