Subject: [PATCH v3 2/4] arm64: dts: google: Add dts directory for Google-designed silicon
Date: Fri, 18 Sep 2026 17:26:35 +0000	[thread overview]
Message-ID: <20260918-contrib-pg-pixel10-initial-dts-v3-2-c94e51140509@linaro.org> (raw)
In-Reply-To: <20260918-contrib-pg-pixel10-initial-dts-v3-0-c94e51140509@linaro.org>

From: Douglas Anderson <dianders@chromium.org>

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.

Changes by Peter Griffin
 * update config symbol help with at least 4 lines to avoid checkpatch
   warning
