[U-Boot] Where to add maintainers for pwm?

Hi,

I am implementing a pwm driver for my SoC (MediaTek MT7688). When running patman it complaints about: <unknown>:0: warning: added, moved or deleted file(s), does MAINTAINERS need updating?

I cannot find any maintainers file for drivers in the drivers/pwm directory.

Where should I add myself as maintainer for this driver?

Regards Micke
