Message-ID <20260722-contrib-pg-pixel10-initial-dts-v2-3-3abae9717feb@linaro.org>
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.
