[PATCH v4 2/5] arm64: dts: imx8mq: add Nitrogen8 SoM
Lucas Stach
dev at lynxeye.de
Mon Jun 14 10:06:30 PDT 2021
This adds the description of the Nitrogen8 System on Module. The module
is quite simple with only a few (almost) fixed regulators and a eMMC
on-board.

v2:
- remove 100/200MHz pinctrl states for usdhc1
- rename i2c nodes
v4:
- enable eMMC high-speed modes, now that we can selectively disable
HS400 mode
