Subject: [PATCH v2] MIPS: Octeon: apply USB FDT fixups also when USB is modular
Date: Tue, 1 Sep 2026 19:33:55 +0000 [thread overview]
Message-ID: <20260901193357.1352617-1-orgads@gmail.com> (raw)
In-Reply-To: <20260827175728.1574-1-orgads@gmail.com>
The uctl/usbn device-tree fixups in octeon_prune_device_tree() - which
set the board's USB reference-clock frequency and type from
__cvmx_helper_board_usb_get_clock_type() - are guarded by
"#ifdef CONFIG_USB", which is false when USB is built as a module. The
fixups then silently disappear and octeon-hcd sees whatever default the
DTS carries (12MHz crystal in octeon_3xxx.dts), leaving the PHY dead or
the bus erroring on boards with a different reference clock.
Use IS_ENABLED() so USB=m gets the same fixups as USB=y.
Fixes: 7fd57ab9d9cf ("MIPS: Octeon: Fix compile error when USB is not enabled.")
