Subject: [PATCH v4 07/12] i3c: dw-i3c-master: Add SETAASA as supported CCC
Date: Tue, 16 Jun 2026 09:54:21 +0000 [thread overview]
Message-ID: <20260616095429.3947205-8-akhilrajeev@nvidia.com> (raw)
In-Reply-To: <20260616095429.3947205-1-akhilrajeev@nvidia.com>
Add SETAASA and SETHID to the supported list of CCC commands for
DesignWare I3C host controller.
SETAASA is a broadcast command that assigns predefined static addresses
to all I3C devices on the bus.
SETHID is to stop HID bit flipping by the SPD Hub to which the SPD devices
are connected. It is a prerequisite command to be sent before SETAASA as
recommended by JESD300-5 and JESD403 sideband bus specifications.
