Subject: [PATCH v3 0/7] 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.
Up to v2, this series also included the fsl_linflexuart driver, which has
been included in Greg Kroah-Hartman's tty git tree[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 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.
