Subject: [PATCH v5 3/4] ARM: dts: qcom: Add support for Samsung Galaxy Tab 4 10.1 LTE (SM-T535)
Date: Tue, 31 Oct 2023 15:00:57 +0100	[thread overview]
Message-ID: <20231031140337.49291-4-newbyte@postmarketos.org> (raw)
In-Reply-To: <20231031140337.49291-1-newbyte@postmarketos.org>

Add a device tree for the Samsung Galaxy Tab 4 10.1 (SM-T535) LTE tablet
based on the MSM8926 platform.

The common dtsi is also modified to describe the widest constraints,
which required modifications to the matisse-wifi dts.
