Subject: [PATCH 08/12] i3c: dw-i3c-master: Add SETAASA as supported CCC
Date: Wed, 18 Mar 2026 22:57:21 +0530	[thread overview]
Message-ID: <20260318172820.13771-9-akhilrajeev@nvidia.com> (raw)
In-Reply-To: <20260318172820.13771-1-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 stops HID bit
flipping by the SPD Hub on 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.
