16:37 <yates> i must be missing it, but where in the imx6 ull applications processor reference manual (chapter 33) is it document how to setup a gpio as input or output?

16:38 <yates> for example, section 33.6.153, GPIO1_IO00, p1768

16:39 <yates> i'm asking from a bare-metal chip configuration POV. e.g., assume i'm writing assembly language.

16:42 <yates> vpeter: ping?

16:43 <vpeter> yates: No idea :(

16:45 <yates> unless, and this would be very unclear, it's the DSE field setting of 000, "output driver disabled"

16:45 <yates> implying input.
