Hello, thank you for checking :). The above link issues a 404. 
Everything should be fine though once all of the below are merged:
https://lore.kernel.org/linux-arm-kernel/53e72e5d-47fc-403d-c969-61b267a9ff15@microchip.com/
https://lore.kernel.org/linux-arm-kernel/1ae89854-74fa-6194-304f-db31d56d3674@microchip.com/

together with the patch series that I linked into the cover letter as a 
dependence:

Thank you,
