Subject: [PATCH v2 14/44] media: ipu6: Add ipu7 mmu support
Date: Fri, 21 Aug 2026 14:42:32 +0300 [thread overview]
Message-ID: <20260821114302.365532-15-antti.laakso@linux.intel.com> (raw)
In-Reply-To: <20260821114302.365532-1-antti.laakso@linux.intel.com>
The ipu7 mmu have similar page tables as ipu6, but e.g. register interface
is different. Add own driver handling ipu7 mmu specifics.
