From 41d62e2f275c44fd47bcd6d856608528006b082b Mon Sep 17 00:00:00 2001 From: Etienne Carriere Date: Mon, 21 Feb 2022 09:22:39 +0100 Subject: sandbox: scmi: test against a single scmi agent As per DT bindings since Linux kernel v5.14, the device tree can define only 1 SCMI agent node that is named scmi [1]. As a consequence, change implementation of the SCMI driver test through sandbox architecture to reflect that. This change updates sandbox test DT and sandbox SCMI driver accordingly since all these are impacted.

For this reason, sandbox SCMI clock driver must emulate all clocks exposed by SCMI server, not only those effectively consumed by some other U-Boot devices. Therefore the sandbox SCMI test driver exposes 3 clocks (IDs 0, 1 and 2) and sandbox SCMI clock consumer driver gets 2 of them.
