A fallback compatible would help here but would still require keeping the current list around for backwards compatibility. As an alternative, let's switch the driver to match the rpmsg_device_id instead, which is always "rpm_requests" on all platforms. Add a check to ensure that there is a device tree node defined for the device since otherwise the of_platform_populate() call will operate on the root node (/). Similar approaches with matching rpmsg_device_id are already used in qcom_sysmon, qcom_glink_ssr, qrtr, and rpmsg_wwan_ctrl.

The Resource Power Manager (RPM) is also such a subsystem, with a remote processor that is running a special firmware. Unfortunately, the RPM never got a dedicated node representing it properly in the device tree. Most of the RPM services are described below a top-level /smd or /rpm-glink node. However, SMD/GLINK is just one of the communication channels to the RPM firmware. For example, the MPM interrupt functionality provided by the RPM does not use SMD/GLINK but writes directly to a special memory region allocated by the RPM firmware in combination with a mailbox. Currently there is no good place in the device tree to describe this functionality. It doesn't belong below SMD/GLINK but it's not an independent top-level device either. Introduce a new "qcom,rpm-proc" compatible that allows describing the RPM as a remote processor/subsystem like all others. The SMD/GLINK node is moved to a "smd-edge"/"glink-edge" subnode consistent with other existing bindings. Additional subnodes (e.g. interrupt-controller for MPM, rpm-master-stats) can be also added there.

Add the same check to qcom_smd_register_edge() as well to ensure that it only succeeds if SMEM is already available - if a driver calls the function and SMEM is not available yet then the initial state will be read incorrectly and the RPMSG devices might never become available.

Note that the DT schema belongs to the remoteproc subsystem while this driver is added inside soc/qcom. I argue that the RPM *is* a remoteproc, but as an implementation detail in Linux it can currently not benefit from anything provided by the remoteproc subsystem. The RPM firmware is usually already loaded and started by earlier components in the boot chain and is not meant to be ever restarted. To avoid breaking existing kernel configurations the driver is always built when smd-rpm.c is also built. They belong closely together anyway.

Mon, 5 Jun 2023 09:09:16 +0200 (CEST) From: Stephan Gerhold Date: Mon, 05 Jun 2023 09:08:28 +0200 Subject: [PATCH 12/14] arm64: dts: qcom: Add rpm-proc node for GLINK gplatforms MIME-Version: 1.0 Message-Id: <20230531-rpm-rproc-v1-12-e0a3b6de1f14@gerhold.net> References: <20230531-rpm-rproc-v1-0-e0a3b6de1f14@gerhold.net> In-Reply-To: <20230531-rpm-rproc-v1-0-e0a3b6de1f14@gerhold.net> To: Bjorn Andersson Cc: Andy Gross , Konrad Dybcio , Rob Herring , Krzysztof Kozlowski , Conor Dooley , Mathieu Poirier , linux-arm-msm@vger.kernel.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org, linux-remoteproc@vger.kernel.org, Stephan Gerhold X-Mailer: b4 0.12.2 Precedence: bulk List-ID: X-Mailing-List: linux-arm-msm@vger.kernel.org Rather than having the RPM GLINK channels as the only child of a dummy top-level rpm-glink node, switch to representing the RPM as remoteproc like all the other remoteprocs (modem DSP, ...). This allows assigning additional subdevices to it like the MPM interrupt-controller or rpm-master-stats.

This allows assigning additional subdevices to it like the MPM interrupt-controller or rpm-master-stats.

For some reason apq8064 also has them all listed in a top-level /smd node, disabled by default. None of the boards enable them. Right now apq8064 only has support for WCNSS/riva, but there the smd-edge is already defined with the same interrupt etc below the riva-pil node. Drop these redundant definitions since the /smd top-level node is now deprecated.
