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 v4:
* Remove the patch 'serial: fsl_linflexuart: Update compatible string'
following its acceptance[7];
* Rebased 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.

From: Mihaela Martinas <[email protected]>
Add configuration option for the NXP S32 platform family in
Kconfig.platforms. For starters, the only SoC supported will be Treerunner
(S32V234), with a single execution target: the S32V234-EVB (rev 29288)
board.

+* Freescale LINFlexD UART
+
+The LINFlexD controller implements several LIN protocol versions, as well as

+
+See chapter 47 ("LINFlexD") in the reference manual[1].
+
+Required properties:
+- compatible :
+ - "fsl,s32v234-linflexuart" for LINFlexD configured in UART mode, which
+ is compatible with the one integrated on S32V234 SoC
+- reg : Address and length of the register set for the device
+- interrupts : Should contain uart interrupt
+
+Example:
+uart0: serial@40053000 {
+ compatible = "fsl,s32v234-linflexuart";
+ reg = <0x0 0x40053000 0x0 0x1000>;

Add initial version of device tree for S32V234-EVB, including nodes for the
4 Cortex-A53 cores, AIPS bus with UART modules, ARM architected timer and
Generic Interrupt Controller (GIC).
Keep SoC level separate from board level to let future boards with this SoC
share common properties, while the dts files will keep board-dependent
properties.

I'm about to apply the patches, but found the messages are using base64
Content-Transfer-Encoding, which is difficult for me to apply patch

Hi Greg,
The series looks good to me. I assume that you will take this patch
and #5.

Hello Shawn,
I will fix this is the next version. Please note that this might take a
while, as the problem is caused by our Exchange server and I need to
receive access to another SMTP server. Unfortunately, this cannot be
worked around with the '--transfer-encoding' option of 'git send-email'
for this particular patch.
Also, please note that there is also a 5th version of this series[1],
submitted on 2 October (there are no significant changes though; the
patches were just rebased). You were not included in the recipients list
because the 'arch/arm64/boot/dts/freescale/fsl-*' pattern in the section
'ARM/FREESCALE LAYERSCAPE ARM ARCHITECTURE' of the MAINTAINERS file no
longer matches the dts/dtsi file names, following the prefix removal you
suggested. Therefore, get_maintainer.pl did not show you as a maintainer
anymore. I will add you to the next version.
Regards,
Stefan
