(Resending as requested by Yixun, this timing adding the SpacemiT mailing list to the CC list.) This series adds reset controller support for the SpacemiT K1 SoC. It is based on Linux v6.14-rc1. It is built upon the clock controller driver that Haylen Chu currently has out for review (currently at v5): https://lore.kernel.org/lkml/20250306175750.22480-2-heylenay@xxxxxxx/ It also depends on two commits that will land in v6.15: 5728c92ae1123 ("mfd: syscon: Restore device_node_to_regmap() for non-syscon nodes") and 7ff4faba63571 ("pinctrl: spacemit: enable config option"). The first patch adds three more system controller CCU nodes to those implemented by the SpacemiT K1. The second updates the existing clock driver with a structure used for OF match data, allowing both clocks and resets to be specified. The third provides code that implements reset functionality. The fourth defines groups of reset controls implemented by the CCUs that have alraady been defined. The fifth makes it possible for a CCU to be defined with resets but no clocks. The sixth defines three new CCUs which define only resets. And the last patch defines these additional syscon nodes in "k1.dtsi".
