That the first patch in the series should add the MODULE_LICENSE to all of files. This keeps things simple, explains our intention with next patches. Daniel.

Hi Anson, Patch series mostly looks good to me. I have a comment about adding the MODULE_LICENSE. This is a pretty important change. Can you please add this change in a separate patch with a proper explanation of why it is needed. Most likely it is because it was forgotten in the previous patches. thanks, daniel.

[PATCH V4 0/9] Support i.MX8 SoCs pinctrl drivers built as module
There are more and mroe requirements that SoC specific modules should be built as module in order to support generic kernel image, such as Android GKI concept. This patch series supports i.MX8 SoCs pinctrl drivers to be built as module, including i.MX8MQ/MM/MN/MP/QXP/QM/DXL SoCs, and it also supports building i.MX common pinctrl driver and i.MX SCU common pinctrl driver as module.
