Hi all! This series adds the nodes to enable the watchdog and USB support for the Exynos990 SoC. The watchdog consists of two clusters (cl0 and cl2). Unsure why Samsung has skipped cl1 on this SoC. Both are enabled and working - tested on a device from the -x1s family. The USB controller of this SoC supports full-speed, high-speed and super-speed operation modes. Due to my inability to get any of my Exynos990 devices to enumerate as super-speed (even under the vendor kernels) only the UTMI+ setup is done - as such, only the high-speed mode is enabled. Dummy regulators are used in place of PMIC provided ones until we implement PMIC. This series depends on the following series: - Watchdog commit: https://lore.kernel.org/all/20250217-exynos990-wdt-v2-0-3eb4fbc113f4@xxxxxxxxxxxxxxxxxxxxxxxxxx - USB commits: - https://lore.kernel.org/all/20250217-exynos990-bindings-usb3-v2-1-3b3f0809f4fb@xxxxxxxxxxxxxxxxxxxxxxxxxx/ - https://lore.kernel.org/all/20250214-exynos990-dwusb-v1-0-d68282c51ba8@xxxxxxxxxxxxxxxxxxxxxxxxxx/ Signed-off-by: Igor Belwon <igor.belwon@xxxxxxxxxxxxxxxxxxxxxxxxxx> --- Igor Belwon (5): arm64: dts: exynos990: Enable watchdog timer arm64: dts: exynos990: Add USB nodes arm64: dts: exynos990-x1s-common: Enable USB arm64: dts: exynos990-c1s: Enable USB arm64: dts: exynos990-r8s: Enable USB arch/arm64/boot/dts/exynos/exynos990-c1s.dts | 16 +++++++ arch/arm64/boot/dts/exynos/exynos990-r8s.dts | 16 +++++++ .../boot/dts/exynos/exynos990-x1s-common.dtsi | 16 +++++++ arch/arm64/boot/dts/exynos/exynos990.dtsi | 55 ++++++++++++++++++++++ 4 files changed, 103 insertions(+) --- base-commit: 783ef70f458b28640a63dda599ae8628c3c7aa2e change-id: 20250217-exynos990-dt-changes-febuary-fbc184e8049d Best regards, -- Igor Belwon <igor.belwon@xxxxxxxxxxxxxxxxxxxxxxxxxx>
