From 7a04f1e3752292d89d3793c4d1977aef15c5a7d3 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Wed, 9 Jun 2021 17:03:35 +0200 Subject: [PATCH 3/7] remoteproc: qcom_q6v5_mss: Populate additional devices from device tree Some devices without own memory resources could be placed anywhere in the device tree but they logically belong to the modem remote processor. Make it possible to probe them when defined under the mpss device tree node by calling of_platform_populate().
