Subject: [PATCH v2 14/15] ARM: dts: imx: Add i.MXRT1170-EVK support
Date:   Thu, 28 Apr 2022 17:48:37 -0400
Message-Id: <20220428214838.1040278-15-Mr.Bossman075@gmail.com>

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

V1 -> V2:
 - Add ipg clock for gpt
 - Change mmc, uart and gpt compatibles
 - Group fsl,pins for dtbs_check
 - Remove underscore from pinctrl_usbotg1_id
 - Remove unused fsl,mux_mask
 - Rename ccm to clock-controller
