[PATCH v2 6/6] riscv: dts: spacemit: Add CTF2301 on K3 CoM260

Tue Jul 21 02:48:32 PDT 2026


Enable I2C6 on the K3 CoM260 module and describe the Sensylink
CTF2301 temperature sensor and fan controller at address 0x4c.

Set the I2C6 pin power source in the board-level pinctrl node
because the IO rail voltage is board-specific.
