From mboxrd@z Thu Jan 1 00:00:00 1970 From: Avaneesh Kumar Dwivedi Subject: [PATCH v5 1/7] remoteproc: qcom: Add private resource struct and new compatible. Date: Thu, 15 Dec 2016 17:51:24 +0530 Message-ID: <1481804490-8583-2-git-send-email-akdwived@codeaurora.org> References: <1481804490-8583-1-git-send-email-akdwived@codeaurora.org> Return-path: In-Reply-To: <1481804490-8583-1-git-send-email-akdwived@codeaurora.org> Sender: linux-kernel-owner@vger.kernel.org To: bjorn.andersson@linaro.org Cc: sboyd@codeaurora.org, agross@codeaurora.org, linux-arm-msm@vger.kernel.org, linux-kernel@vger.kernel.org, linux-remoteproc@vger.kernel.org, Avaneesh Kumar Dwivedi List-Id: linux-arm-msm@vger.kernel.org Make provison for private resource specific to each compatible, so a private resource struct is introduced which will house clock, regulator etc. related info corresponding to each compatible to use later to initialize hardware. Also add new compatible in documentation.
