Hi Alex:
Thanks for sending this patch series
Can you also CC spacemit mailing list: spacemit@xxxxxxxxxxxxxxx
it should be handled automaticlly in next 6.15-rc1 version as the
MAINTAINERS file updated
https://web.git.kernel.org/pub/scm/linux/kernel/git/soc/soc.git/commit/?id=4a0c4e723c94
Sorry about that. I will copy it on my next version.
Are you asking me to RESEND this series with that addition?

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").
you can use b4 to handle patch dependency, and currently you may got
linux.riscv.bot complaint, but may fix later
https://github.com/linux-riscv/github-ci/issues/24
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".
All of these patches are available here:
