Pull SoC dt updates from Arnd Bergmann:
"There are five sets of new SoCs that get added in existing families,
all of them being either upgrades or cut-down versions of the older
chips:
- Apple M2 Pro, M2 Max and M2 Ultra, used in the 2022/2023 generation
of high-end workstations and laptops from Apple. Linux has been
working on these for a while but stil requires patches.
- Axis Artpec8 is an Armv8 chip based on Samsung Exynos design,
unlike the earlier Armv7 Artpec6 from the same company that was
part of a separate family of chips.
- NXP i.MX91 is a cut-down version of i.MX93, using only a single
Cortex-A55 core.
- Qualcomm Lemans Auto is a variant of the Lemans SoC that was
originally merged under the sa8775p name, the differences being
mostly the firmware configuration of the platform.
- Four new Renesas SoCs RZ/T2H (r9a09g077m44), RZ/N2H (r9a09g087m44),
RZ/T2H (r9a09g077), and RZ/N2H (r9a09g087) are all industrial
bedded SoCs based on Cortex-A55 cores
In total, there are 65 new machines, including:
- Industrial embedded system and single-board computers based on NXP,
Allwinner, TI, Rockchips, Marvell, Xilinx Spacemit, Starfive chips.
- Reference boards for the newly added Renesas, Qualcomm, NXP and
Axis ARMv8 chips as well as Microchip's MPFS RISC-V SoC
- Laptops and Workstations using Apple M2 and Qualcomm Snapdragon X1
chips.
- Several Samsung phones using Qualcomm Snapdragon chips
- Set-top boxes based on Allwinner H313
- Five BMC boards using 32-bit ASpeed SoCs
- Three network routers using IXP4xx (ARMv5!) and Broadcom bcm4708
(ARMv7) SoCs
Two machines get phased out because they were available only in small
quantities but never made it into products: one STi407 based reference
board, and a Snapdragon 845 based Chromebook.
Aside from the newly added machines, a lot of work went into improving
hardware support on the existing machines and cleaning up contents for
validation"
