Subject[PATCH v9 1/4] remoteproc: qcom: wcss: populate hardcoded param using driver data
Date
From: Govind Singh <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.
