Hi,

* Drew Fustini [off-list ref] [200722 12:09]:
Change the handling of pin config flags from if/else to switch
statement to make the code more readable and cleaner.

Suggested-by: Gustavo A. R. Silva <redacted>
Signed-off-by: Drew Fustini <redacted>
This looks OK to me:

Acked-by: Tony Lindgren <tony@atomide.com>

I've lost track of the pending pinctrl/gpio/dts patches you've
posted :) Care to also summarized the pending ones and repost
them now that v5.9-rc1 is out?

Regards,

Tony
