[PATCH 2/5] sandbox: scmi: test against a single scmi agent
Etienne Carriere
etienne.carriere at linaro.org
Fri Feb 11 13:07:22 CET 2022
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.
