i.MX8MM USB OTG ID Documentation

felixradensky — Tue, 03 Dec 2019 07:28:18 GMT

Hello,

The description of USBNC_n_CTRL2 register in i.MX8MM Reference Manual V2 (chapter 11.1.42, page 2822) mentions DIG_ID_SEL field and IOMUXC_USB_OTG*_ID_SELECT_INPUT registers, however these registers are not documented in the manual. Please provide the missing information.

Thanks.

Felix.
