The base for a patch series is generally the most recent rc1. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit.
v2 - remove the patch that modified 8250_of.c to keep it from registering before this driver when this driver was deferred as it was getting it's "clocks". This was fixed by changing the Device Tree entry to remove "clock-frequency". This results in both drivers getting "clocks" and getting same deferral. Add UART driver for the new Broadcom 8250 based STB UART. The new UART is backward compatible with the standard 8250, but has some additional features. The new features include a high accuracy baud rate clock system and DMA support.
