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. Up to v2, this series also included the fsl_linflexuart driver, which has been included in Linux 5.4-rc1[3]. In the future, we aim to submit multiple drivers upstream, which can be found in the kernel of our Auto Linux BSP[4] ("ALB"), starting with basic pinmuxing, clock and uSDHC drivers. For validation, you can use the U-Boot bootloader in the ALB[5], 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 [6]. Changes in v6: * In the patch 'serial: fsl_linflexuart: Be consistent with the name', avoid updating the definition PORT_LINFLEXUART; that was an independent fix which has been submitted and accepted[9] separately; * Avoid using 'base64' as 'Content-Transfer-Encoding'. Changes in v5: * Remove the patch 'dt-bindings: serial: Document Freescale LINFlexD UART' following its acceptance in Linux 5.4-rc1[8]; * Rebase the other patches on v5.4-rc1. Changes in v4: * Remove the patch 'serial: fsl_linflexuart: Update compatible string' following its acceptance[7]; * Rebase the patch 'serial: fsl_linflexuart: Be consistent with the name' on the tty-next branch in Greg's tty git tree. Changes in v3: * Remove the patch 'tty: serial: Add linflexuart driver for S32V234' following its acceptance[3]; * Replace 'Freescale' with 'NXP' in the ARCH_S32 config definition and the 'model' property from the device tree; * Remove the 'fsl-' prefixes from the dtsi and dts file names; * Move the 'model' property from (fsl-)s32v234.dtsi to s32v234-evb.dts; * Add newlines between the cpu nodes in s32v234.dtsi; * Make use of GIC_SPI, GIC_PPI, GIC_CPU_MASK_SIMPLE and IRQ_TYPE_* in the 'interrupts' tuples; * Move the 'timer' and 'interrupt-controller' nodes before 'soc' in s32v234.dtsi; * Be consistent with the 'LINFlexD' spelling in documentation, strings and comments; add new patch 'serial: fsl_linflexuart: Be consistent with the name' to update the LINFlexD driver as well; * Remove from fsl,s32-linflexuart.txt a statement regarding the limitation to UART mode; * Make the compatible string SoC specific ("fsl,s32v234-linflexuart"); add new patch 'serial: fsl_linflexuart: Update compatible string' to update the LINFlexD driver as well; * In the LINFlexD binding documentation, insert a space between label and node name and remove the 'status' property. Changes in v2: * Update the entry in fsl.yaml to apply to all S32V234 based boards; * Add chosen node to dts, with a 'stdout-path' property for earlycon; * Remove linflex_verify_port(), because it was only called from uart_set_info(), which was going to always fail at the "baud_base < 9600" check, as we are not using uartclk from uart_port yet; * Fix compatible string used in OF_EARLYCON_DECLARE.
