Subject: [PATCH v2 21/44] media: ipu6: Add isys firmware ops
Date: Fri, 21 Aug 2026 14:42:39 +0300 [thread overview]
Message-ID: <20260821114302.365532-22-antti.laakso@linux.intel.com> (raw)
In-Reply-To: <20260821114302.365532-1-antti.laakso@linux.intel.com>
Add struct for ipu6 firmware ops. This is a preparation to
add support for ipu7 firmware communication.
