[PATCH v3 4/6] arm64: dts: exynos8895: add a node for mmc

From: Ivaylo Ivanov
Date: Sun Jan 05 2025 - 11:14:48 EST


Add an MMC node in order to allow devices with that SoC to make use of
it. It's typically used as a secondary storage option for SD cards. In
the vendor kernels, it's labelled as mmc_2, but since there don't seem to
be any other blocks, treat it as the only MMC.
