Subject: [PATCH 3/4] riscv: dts: spacemit: enable eMMC on Milk-V Jupiter
Date: Thu, 14 May 2026 17:56:23 +0200 [thread overview]
Message-ID: <20260514160356.1642075-4-aurelien@aurel32.net> (raw)
In-Reply-To: <20260514160356.1642075-1-aurelien@aurel32.net>
The Milk-V Jupiter board has a connector for an eMMC module. Add an
entry for it in the device tree and alias it mmc0. As it is not
populated by default, do no mark it as non-removable.
