Subject: [PATCH v7 6/7] ARM: dts: imx: Add i.MXRT1050-EVK support
From: Giulio Benetti <giulio.benetti@...ettiengineering.com>
The NXP i.MXRT1050 Evaluation Kit (EVK) provides a platform for rapid
evaluation of the i.MXRT, which features NXP's implementation of the Arm
Cortex-M7 core.
The EVK provides 32 MB SDRAM, 64 MB Quad SPI flash, Micro SD card socket,
USB 2.0 OTG.
This patch aims to support the preliminary booting up features
as follows:
GPIO
LPUART
SD/MMC

[Jesse: Add clock-parents, edma, usdhc, anatop, remove old pinctl]
---
V1->V2:
* dtsi: Add clock parent definitions
* dtsi: Change hex values to lowercase
* dtsi: Move anatop definition from driver
* dts: Remove unused pin controll (semc)
* dts: Use moved pin controll header
* Move aliases from dtsi to dts
* Change commit description
* Change licence to "GPL-2.0+ OR MIT"
V2->V3:
* Remove bootargs, comments, unused container
* Remove unnecessary new lines
* Rename imxrt to imxrt1050 for seiral and mmc
* GPT uses own clock
* fix memory@0
* Change GPT compatible handles
V3->V4:
* Remove "fsl,imx-osc"
* Add space on serial compatible
* Change "iomuxc@" to "pinctrl@"
* Change "ccm@" to "clock-controller@"
* Change "fsl,imxrt-gpio" to "fsl,imxrt1050-gpio"
V4->V5:
* Nothing done
V5->V6:
* Nothing done
V6->V7:
* Add fixed clock for GPT
* Fix lpuart compatible
* Add usdhc compatible
