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 board 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 v2 ================ Addressing Krzysztof's feedback: * chagallwifi -> chagall-wifi and Chagall WiFi in messages and comments * Re-write commit message for patch 3, use commit hash and ("subject"), move hint about bootloader issue to galaxy-tab-common.dtsi * Fix s2mps11 regulator nodes, use &ldoXX_reg handle for device customisation * Re-add usbdrd supplies (works after fixing regulator nodes) * Remove unnecessary, duplicate, compatible in galaxy-tab-common.dtsi * Remove extra clocks xxti and xusbxti * Prefix key- to gpio-keys * Add pinctrl pins to mmc_2. card-detect pin is different than for other Exynos 5420 devices, so define and use mmc2_cd node under pinctrl_0 Additional changes: * Add/fix supplies of mmc_0 and mmc_2 (vmmc-supply for mmc0 is unknown) * Sort mmc_X properties alphabetically * Fix IRQ pin for s2mps11, it was wrong (gpx3-2 -> gpx3-0) * Mark LDO31 as varying between devices as well, it differs between WiFi and LTE tablet versions * Fix typo for LDO5 (regulato-name -> regulator-name) * Remove regulator-ramp-delay from buck regulators, based on exynos5420-arndale-octa there should be no need to set it 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 Chagall WiFi board binding ARM: exynos: only do SMC_CMD_CPU1BOOT call on Exynos4 ARM: dts: Add support for Samsung Chagall WiFi .../bindings/arm/samsung/samsung-boards.yaml | 1 + arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/exynos5420-chagall-wifi.dts | 65 ++ .../dts/exynos5420-galaxy-tab-common.dtsi | 666 ++++++++++++++++++ arch/arm/mach-exynos/firmware.c | 4 +- 5 files changed, 736 insertions(+), 1 deletion(-) create mode 100644 arch/arm/boot/dts/exynos5420-chagall-wifi.dts create mode 100644 arch/arm/boot/dts/exynos5420-galaxy-tab-common.dtsi -- 2.34.1
