From: Douglas Anderson <[email protected]> The first four Google Tensor SoCs were offshoots of Samsung Exynos SoCs and their device trees were organized under the "exynos/google" directory. Starting with the Google Tensor G5 SoC in Pixel 10 phones, Google Tensor SoCs are now of Google's own design. Add a location in the tree to store these device tree files.
