Subject: [PATCH AUTOSEL 6.12 30/36] ACPI/IORT: Add PMCG platform information for HiSilicon HIP09A
Date: Wed, 11 Dec 2024 13:49:46 -0500 [thread overview]
Message-ID: <20241211185028.3841047-30-sashal@kernel.org> (raw)
In-Reply-To: <20241211185028.3841047-1-sashal@kernel.org>
From: Qinxin Xia <xiaqinxin@huawei.com>
[ Upstream commit c2b46ae022704a2d845e59461fa24431ad627022 ]
HiSilicon HIP09A platforms using the same SMMU PMCG with HIP09
and thus suffers the same erratum. List them in the PMCG platform
information list without introducing a new SMMU PMCG Model.
Update the silicon-errata.rst as well.
