Subject: [PATCH v5 5/7] remoteproc: qcom: wcss: populate hardcoded param using driver data
Date: Fri, 26 Jul 2019 14:53:30 +0530	[thread overview]
Message-ID: <20190726092332.25202-6-govinds@codeaurora.org> (raw)
In-Reply-To: <20190726092332.25202-1-govinds@codeaurora.org>

Q6 based WiFi fw loading is supported across
different targets, ex: IPQ8074/QCS404. In order to
support different fw names/pas id etc, populate
hardcoded param using driver data.
