Subject: [PATCH 0/6] Add initial support for S32V234-EVB

Hello,

NXP's S32V234[1] ("Treerunner") vision microprocessors are targeted for
high-performance, computationally intensive vision and sensor fusion
applications that require automotive safety levels. They include leading
edge Camera Vision modules like APEX-2, ISP and GPU. The S32V234-EVB and
S32V234-SBC boards are available for customer evaluation.

The following patch series introduces minimal enablement support for the
NXP S32V234-EVB2[2] board, which leverages most of the SoC capabilities.
The series includes a driver for operating the on-chip LINFlexD controller
in UART mode.

In the future, we aim to submit multiple drivers upstream, which can be
found in the kernel of our Auto Linux BSP[3] ("ALB"), starting with basic
pinmuxing, clock and uSDHC drivers.

For validation, you can use the U-Boot bootloader in the ALB[4], which we
build and test with our patched version of the Linaro GCC 6.3.1 2017.05
toolchain for ARM 64-bit, with sources available on [5].
