From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Sricharan R Subject: [PATCH V6 4/5] remoteproc: qcom: Add support for q6v5-wcss pil Date: Mon, 14 May 2018 16:16:51 +0530 Message-Id: <1526294812-23390-5-git-send-email-sricharan@codeaurora.org> In-Reply-To: <1526294812-23390-1-git-send-email-sricharan@codeaurora.org> References: <1526294812-23390-1-git-send-email-sricharan@codeaurora.org> To: bjorn.andersson@linaro.org, ohad@wizery.com, robh+dt@kernel.org, mark.rutland@arm.com, andy.gross@linaro.org, david.brown@linaro.org, linux-remoteproc@vger.kernel.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org, linux-arm-msm@vger.kernel.org, linux-soc@vger.kernel.org, sibis@codeaurora.org Cc: sricharan@codeaurora.org List-ID: IPQ8074 has an integrated Hexagon dsp core q6v5 and a wireless lan (Lithium) IP. An mdt type single image format is used for the firmware. So the mdt_load function can be directly used to load the firmware. Also add the relevant resets required for this core.
