Subject: [PATCH v7 4/5] riscv: dts: spacemit: Add a PCIe regulator
Date: Thu, 18 Dec 2025 09:12:30 -0600 [thread overview]
Message-ID: <20251218151235.454997-5-elder@riscstar.com> (raw)
In-Reply-To: <20251218151235.454997-1-elder@riscstar.com>
Define a 3.3v fixed voltage regulator to be used by PCIe on the
Banana Pi BPI-F3. On this platform, this regulator is always on.
