Add a device tree for the Samsung Galaxy Tab 4 10.1 (SM-T530) wifi tablet based on the apq8026 platform. Currently supported are accelerometer sensor, hall sensor, internal storage, physical buttons (power & volume), screen (based on simple-framebuffer set up by the bootloader), sdcard, touchscreen and USB. Signed-off-by: Matti Lehtimäki <matti.lehtimaki@xxxxxxxxx> --- Changes in v4: - Move delete-node to memory-region - Move usb-switch node to blsp_i2c4 Changes in v3: - Fix sdhc_2 bus width - Reorder includes Changes in v2: - Change codename to matisse-wifi - Remove msm-id, not needed when lk2nd is used - Remove unused labels from reserved memory regions - Rename muic node --- arch/arm/boot/dts/Makefile | 1 + .../dts/qcom-apq8026-samsung-matisse-wifi.dts | 453 ++++++++++++++++++ 2 files changed, 454 insertions(+) create mode 100644 arch/arm/boot/dts/qcom-apq8026-samsung-matisse-wifi.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 05d8aef6e5d2..69f6bbcf90c6 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -1027,6 +1027,7 @@ dtb-$(CONFIG_ARCH_QCOM) += \ qcom-apq8016-sbc.dtb \ qcom-apq8026-asus-sparrow.dtb \ qcom-apq8026-lg-lenok.dtb \ + qcom-apq8026-samsung-matisse-wifi.dtb \ qcom-apq8060-dragonboard.dtb \ qcom-apq8064-cm-qs600.dtb \ qcom-apq8064-ifc6410.dtb \ diff --git a/arch/arm/boot/dts/qcom-apq8026-samsung-matisse-wifi.dts b/arch/arm/boot/dts/qcom-apq8026-samsung-matisse-wifi.dts new file mode 100644 index 000000000000..1324a4898f3c --- /dev/null +++ b/arch/arm/boot/dts/qcom-apq8026-samsung-matisse-wifi.dts @@ -0,0 +1,453 @@ +// SPDX-License-Identifier: BSD-3-Clause +/* + * Copyright (c) 2022, Matti Lehtimäki <matti.lehtimaki@xxxxxxxxx> + */ + +/dts-v1/;
