I've thrown these patches into my tree: https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux.git/log/?h=k230-basic I do have one of these boards, but I'm fairly limited at the moment between the various linux-related and work demands on my time, so it's pretty unlikely that I'll do anything with it myself. Thanks, Conor.

Here is the k230 clock driver based on Linux-6.6: https://github.com/ruyisdk/linux-xuantie-kernel/commit/196242fd9b9b4a191dab0c7c3c5bf851ed857d8d pinctrl: https://github.com/ruyisdk/linux-xuantie-kernel/commit/baf26b6622c9de2ff64a6ed58eeeb98c8b2c828b No reset driver. Most of the k230 drivers are under Linux-5.10, and we are porting them into the newest version of Linux, which takes time. So, if the clock & punctual drivers mentioned above could satisfy the minimum requirements for the platforms, we will update the version of this series as a supplement.

I don't understand how that changes anything, these are all out of tree drivers based on an old kernel. I know that there are drivers for a lot of the peripherals that are in-use in the vendor tree etc. What I am looking to happen, before I apply patches for the k230, is that the clock dt-bindings will have landed in linux-next - and ideally the pinctrl ones too. Thanks, Conor.

Thx. If you could get someone to work on them, or convince Canaan to do it etc, that'd be neat :)

I understand about this. I do some initial support for K230 only for my evaluation purpose and propose this tree to provide information for others to boot up a minimal kernel and also have another patch [1] to have a USB node so we will able to run a distro like Debian over NFS rootfs by USB ethernet which is on canmv k230 board. But I want to say I may have no time to do further driver development. I have done this for my evaluation purpose to get some performance metrics on real RVV chips for research usage since I’m a Ph.D. student focused on computer architecture. I have to devote my time to my research work. If anyone wants to do some further driver development, please don’t hesitate to do so. Don’t imagine I may be doing this, so you may do duplicate work. I’m too busy to do that. [1] https://lore.kernel.org/linux-riscv/tencent_E9B853316D217B8D1E7CDF8288DA5E8ED908@qq.com/ Thanks, Yangyu Chen > Thanks, > Conor.
