Subject: [PATCH] phy: spacemit: enable K1 USB 2.0 PHY by default on ARCH_SPACEMIT
Date: Tue, 25 Aug 2026 07:21:58 +0200 [thread overview]
Message-ID: <20260825052158.66367-1-bbanelli@gmail.com> (raw)
PHY_SPACEMIT_K1_PCIE has "default ARCH_SPACEMIT", but
PHY_SPACEMIT_K1_USB2, twelve lines 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.

Enable this to support K1 USB 2.0 PHY driver. This driver takes care of
enabling and clock setup and will be used by K1 udc/ehci/otg/xhci driver.
