[PATCH v1 11/12] ARM: dts: imx: Add i.MXRT1170-EVK support

Jesse Taube mr.bossman075 at gmail.com
Sat Mar 26 07:43:12 PDT 2022


The NXP i.MXRT1170 Evaluation Kit (EVK) provides a platform for rapid
evaluation of the i.MXRT, which features NXP's implementation of the Arm
Cortex-M7 and M4 core.

The EVK provides 64 MB SDRAM, 128 MB Quad SPI flash, Micro SD card socket,
two USB 2.0 OTG, and two Ethernet ports.

This patch aims to support the preliminary booting up features
as follows:
GPIO
LPUART
SD/MMC
