From 7cc406151a99ec1643ed8bf3c52fa5fbdf74238f Mon Sep 17 00:00:00 2001 From: Jasper Korten Date: Sat, 7 Jan 2023 19:19:10 +0500 Subject: [PATCH] arm64: dts: qcom: Add device tree for Samsung Galaxy Tab A 9.7 (2015) The Galaxy Tab A 9.7 (2015) is a Snapdragon 410 based tablet. This commit introduces basic support for the tablet including the following features: - SDHCI (internal and external storage) - USB Device Mode - UART - Regulators - WCNSS (WiFi/BT) - GPIO keys - Fuel gauge - Touchscreen - Accelerometer Part of the DT is split out into a common dtsi since the tablet shares majority of the design with another variant having a different screen size.
