The base for a patch > series is generally the most recent rc1. This series can be applied to linux-next/master branch. The header file 'imx8-lpcg.h' was added with the below commit on that branch: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/include/dt-bindings/clock/imx8-lpcg.h?id=540742fb109fa4a65f116db9edc28ab1bd2c872d With that header file, this patch may pass 'make dt_binding_check'.

I guessed that reviewing this before sending, but I want it abundantly clear what the result of applying this might be and it wasn't mentioned in this patch. Plus linux-next is a base no one can apply patches to, so should you be sending patches based on it? It's also the merge window, so maybe wait until rc1 when your dependency is in and the patch can actually be applied. Also, the drm-misc folks will still need to know they need to merge rc1 in before this is applied. Rob

Yeah, 'base-commit' is good, but a base commit should be 'well-known' as doc[1] indicates, otherwise, it is likely unfound. So, it seems that linux-next is worthy of a try.
