The J784S4 SoC belongs to the K3 Multicore SoC architecture platform,
providing advanced system integration in automotive ADAS applications
and industrial applications requiring AI at the network edge. This SoC
extends the Jacinto 7 family of SoCs with focus on high performance
providing significant levels of processing power, graphics capability,
video and imaging processing, virtualization and coherent memory
support.
Some highlights of this SoC are:
* Eight Cortex-A72s in dual clusters, four clusters of lockstep capable
dual Cortex-R5F MCUs, Deep-learning Matrix Multiply Accelerator(MMA),
four C7x floating point Vector DSP.
* 3D GPU: Automotive grade IMG BXS-4-64
* Two Vision Processing Accelerator (VPAC) with image signal processor
and Depth and Motion Processing Accelerator (DMPAC)
* Three CSI2.0 4L RX plus one eDP/DP, two DSI Tx and one DPI interface.
* Two RGMII/RMII interfaces,
* Integrated ethernet switch supporting up to 8 external ports,
* Two 4 lane PCIe-GEN3 controllers, USB3.0 Dual-role device subsystems,
* Up to 20 MCANs, 5 McASP, eMMC and SD, OSPI/HyperBus memory controller,
QSPI, I3C and I2C, eCAP/eQEP, eHRPWM, MLB among other peripherals.
* Hardware accelerator blocks containing AES/DES/SHA/MD5 called SA2UL
management.

2.17.1
Add pinctrl macros for J784s4 SoC. These macro definitions are
similar to that of J721s2, but adding new definitions to avoid
any naming confusions in the soc dts files.
checkpatch insists the following error exists:
ERROR: Macros with complex values should be enclosed in parentheses
However, we do not need parentheses enclosing the values for this
macro as we do intend it to generate two separate values as has been
done for other similar platforms.

I guess you will merge these patches together?
Tell me if you rather want that I apply this one patch to the pinctrl tree.
Yours,

I will the patch via TI K3 SoC tree once other patches are in good shape.
Thanks for the review!
