Subject: [PATCH v11 4/6] clk: spacemit: define three reset-only CCUs
Date: Thu, 12 Jun 2025 20:11:36 -0500 [thread overview]
Message-ID: <20250613011139.1201702-5-elder@riscstar.com> (raw)
In-Reply-To: <20250613011139.1201702-1-elder@riscstar.com>
Three CCUs on the SpacemiT K1 SoC implement only resets, not clocks.
Define the CCU data for these resets so their auxiliary devices get
created.
