Merge tag 'arm-newsoc-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull new ARM SoC support from Arnd Bergmann:
"There are three SoC families newly dded to the 32-bit and 64-bit Arm
architecture code in the kernel this time:
- Daniel Palmer adds initial support for two chips made by MStar, a
taiwanese SoC manufacturer that became part of Mediatek in 2012.
For now, the added support is fairly minimal, with just two of its
Cortex-A7 based 32-bit camera chips getting support for a limited
set of on-chip peripherals.
- Lars Povlsen from Microchip adds support for their new Sparx5
family of ethernet switch chips using 64-bit Cortex-A53 cores.
These are descended from earlier VSC7xxx SparX and Ocelot chips
using 32-bit MIPS cores.
- Daniele Alessandrelli from Intel adds support for the new Keem Bay
SoC for computer vision, built around a Movidius VPU with Linux
running on Arm Cortex-A53 cores"
