Subject: [PATCH v4 6/7] riscv: dts: spacemit: add a PCIe regulator
Date: Thu, 30 Oct 2025 17:02:57 -0500 [thread overview]
Message-ID: <20251030220259.1063792-7-elder@riscstar.com> (raw)
In-Reply-To: <20251030220259.1063792-1-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.
