The BPI-CM6 is an industrial-grade RISC-V compute module powered by the SpacemiT K1 SoC, featuring board-to-board connectors similar to the Raspberry Pi CM4 form factor. For evaluation and development, the module is paired with a companion IO carrier board. During the board bring-up, GPIO45 and GPIO46 were found to be used by the BPI-CM6 hardware as Ethernet PHY reset GPIOs, while the common K1 GMAC pinctrl groups currently mux them as optional GMAC reference clock pins. Since the reference clock pins are not required on all K1 boards, the first patch separates them into independent pinctrl groups so board DTS files can select them only when the signal is actually wired. This is based on the "dt-for-next" branch of the spacemit-com/linux.
