Subject: [PATCH v2 4/6] riscv: dts: spacemit: enable the i2c8 adapter
Date: Thu, 19 Jun 2025 08:51:48 -0500	[thread overview]
Message-ID: <20250619135151.3206258-5-elder@riscstar.com> (raw)
In-Reply-To: <20250619135151.3206258-1-elder@riscstar.com>

Define properties for the I2C adapter that provides access to the
SpacemiT P1 PMIC.  Enable this adapter on the Banana Pi BPI-F3.
