Linus Torvalds 115e74a29b soc: dt changes for 6.17 
There are a few new variants of existing chips:
 
  - mt6572 is an older mobile phone chip from mediatek that was
    extremely popular a decade ago but never got upstreamed until now.
 
  - exynos2200 is a recent high-end mobile phone chip used in a
    few Samsung phones like the Galaxy S22
 
  - Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M
    (R8A779H0) and used in automotive applications
 
  - Tegra264 is a new chip from NVIDIA, but support is fairly minimal
    for now, and not much information is public about it.
 
 There are five more chips in a separate branch, as those are new
 chip families that I merged along with the necessary infrastructure.
 
 New board support is not that exciting, with a total of 33 newly
 added machines here:
 
  - Evaluation platforms for the chips above, plus TI am62d2 and
    Sophgo sg2042.
 
  - Six 32-bit industrial boards based on stm32, imx6 and am33 chips,
    plus eight 64-bit rockchips rk33xx/rk35xx, am62d2, t527, imx8 and
    imx95.
 
  - Two newly added ASPEED BMC based motherboards, and one that got
    removed
 
  - Phones and Tablets based on 32-bit mt6572, tegra30 and 64-bit
    msm8976 SoCs
 
  - Three Laptops based on Mediatek mt8186 and Qualcomm Snapdragon X1
 
  - A set-top box based on Amlogic meson-gxm.
 
 Updates for existing machines are spread over all the above families.
 One notable change here is support for the RP1 I/O chip used in
 Raspberry Pi 5.
