Subject: [PATCH v3] clk: spacemit: Fix module build for spacemit common ccu driver
Date: Thu, 18 Dec 2025 08:42:27 +0800 [thread overview]
Message-ID: <20251218004227.221861-1-inochiama@gmail.com> (raw)
For build spacemit common clock driver as a module, the build
process require MODULE_LICENSE()/MODULE_DESCRIPTION() globally
and EXPORT_SYMBOL() for every exposed symbol. Otherwise, the
build will fail.
Add these missing hints, so the driver can be built as a module.
Fixes: 1b72c59db0ad ("clk: spacemit: Add clock support for SpacemiT K1 SoC")
