Subject: [PATCH v2 2/2] phy: spacemit: enable K1 USB 2.0 PHY by default on ARCH_SPACEMIT
Date: Tue, 25 Aug 2026 08:50:07 +0200	[thread overview]
Message-ID: <20260825065007.69353-3-bbanelli@gmail.com> (raw)
In-Reply-To: <20260825065007.69353-1-bbanelli@gmail.com>

PHY_SPACEMIT_K1_PCIE has "default ARCH_SPACEMIT", but
PHY_SPACEMIT_K1_USB2, directly below it in the same file, does not.
Since the symbol is also absent from arch/riscv/configs/defconfig, a
plain "make defconfig" build for a SpacemiT K1 board ends up with the
USB 2.0 PHY driver disabled.

dwc3-generic-plat needs that PHY, so the result is a kernel with no
working USB at all on boards such as the Milk-V Jupiter, where all four
USB 3.0 type-A ports hang off the single dwc3 controller.

Give it the same default as its sibling.
