From 689204be9744db24fc8031229946f045fae02c07 Mon Sep 17 00:00:00 2001 From: AKASHI Takahiro Date: Wed, 11 Oct 2023 19:06:55 +0900 Subject: firmware: scmi: use a protocol's own channel if assigned SCMI specification allows any protocol to have its own channel for the transport. While the current SCMI driver may assign its channel from a device tree, the core function, devm_scmi_process_msg(), doesn't use a protocol's channel, but always use an agent's channel. With this commit, devm_scmi_process_msg() tries to find and use a protocol's channel. If it doesn't exist, use an agent's.
