Subject: [PATCH 3/3] soc: samsung: exynos-chipid: Add Exynos850 support
Date: Tue, 12 Oct 2021 20:16:24 +0300 [thread overview]
Message-ID: <20211012171624.14338-3-semen.protsenko@linaro.org> (raw)
In-Reply-To: <20211012171624.14338-1-semen.protsenko@linaro.org>
Add chip-id support for Exynos850 SoC. Despite its "E3830" ID, the
actual SoC name is Exynos850 (Exynos3830 name is internal and outdated).
