This initial devicetree adds support for accessing device over USB or UART, and allows using a rootfs in either the internal eMMC or an external sdcard. 4 out of 8 CPUs are brought up when device boots, which is the same as on the somewhat similar device exynos5420-arndale-octa. Patch 2 is necessary after a secure-firmware node is added, otherwise device hangs during the CPU1BOOT secure monitor call. Without the secure-firmware node we are not able to bring up any secondary CPUs. Changes since v1 ================ Fix mmc_0 and usbdrd in patch 3: * Remove extra, non supported, options from mmc_0 node * Do not set usbdrd supplies. Usb networking does not work with them specified, but it works fine with dummy regulators Henrik Grimler (3): dt-bindings: arm: samsung: document chagallwifi board binding ARM: exynos: only do SMC_CMD_CPU1BOOT call on Exynos4 ARM: dts: Add support for Samsung Chagallwifi .../bindings/arm/samsung/samsung-boards.yaml | 1 + arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/exynos5420-chagallwifi.dts | 57 ++ .../dts/exynos5420-galaxy-tab-common.dtsi | 633 ++++++++++++++++++ arch/arm/mach-exynos/firmware.c | 4 +- 5 files changed, 695 insertions(+), 1 deletion(-) create mode 100644 arch/arm/boot/dts/exynos5420-chagallwifi.dts create mode 100644 arch/arm/boot/dts/exynos5420-galaxy-tab-common.dtsi
