The NXP i.MX 7ULP Evaluation Kit (EVK) provides a platform for rapid evaluation of the i.MX 7ULP, which features NXP's advanced implementation of the Arm Cortex-A7 core, the Arm Cortex-M4 core, as well as a 3D and 2D Graphics Processing Units (GPUs). The EVK enables HDMI output for simple out-of-the-box to bring up but allows reconfiguration for MIPI displays. The EVK is designed as a System-On-Module(SOM) board that connects to an associated baseboard. The SOM provides 1 GB LPDDR3, 8 MB Quad SPI flash, Micro SD 3.0 card socket, WiFi/ Bluetooth capability, USB 2.0 OTG with Type C connector and an NXP PF1550 power management IC (PMIC). The baseboard provides additional capabilities including a full SD/MMC 3.0 card socket, audio codec, multiple sensors, an HDMI connector, and an alternate MIPI display connector. Additionally, the EVK facilitates software development with the ultimate goal of faster time to market through the support of both Linux OS and AndroidTM rich operating systems, as well as FreeRTOS. This patch aims to support the preliminary booting up features as follows: GPIO LPUART FEC SD/MMC See more board details: https://www.nxp.com/products/processors-and-microcontrollers/ arm-based-processors-and-mcus/i.mx-applications-processors/ i.mx-7-processors/evaluation-kit-for-the-i.mx-7ulp-applications -processor:MCIMX7ULP-EVK Cc: Rob Herring <robh+dt@kernel.org> Cc: Shawn Guo <shawnguo@kernel.org> Cc: devicetree@vger.kernel.org Cc: Sascha Hauer <kernel@pengutronix.de> Reviewed-by: Fabio Estevam <festevam@gmail.com> Signed-off-by: Dong Aisheng <aisheng.dong@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
