Nanopi A64 features - Allwinner A64, 64-bit Quad-core Cortex-A53@648MHz to 1.152GHz, DVFS - 1GB DDR3 RAM - MicroSD - Gigabit Ethernet (RTL8211E) - Wi-Fi 802.11b/g/n - IR receiver - Audio In/Out - Video In/Out - Serial Debug Port - microUSB 5V 2A DC power-supply Signed-off-by: Jagan Teki --- Changes for v5: - Add AXP803 PMIC regulator support. Changes for v4: - Rebased and droped wi-fi related nodes, since it require other changes to taken care. Changes for v3: - Fix to use mmc1 for SDIO instead of mmc2 - Replace buswidth by 4 instead of 8 mmc1 - Drop cap-mmc-hw-reset for mmc1 Changes for v2: - Added ohci0, ehci0, ohic1, ehci1, usbphy. - Tested on A64 arch/arm64/boot/dts/allwinner/Makefile | 1 + .../boot/dts/allwinner/sun50i-a64-nanopi-a64.dts | 205 +++++++++++++++++++++ 2 files changed, 206 insertions(+) create mode 100644 arch/arm64/boot/dts/allwinner/sun50i-a64-nanopi-a64.dts diff --git a/arch/arm64/boot/dts/allwinner/Makefile b/arch/arm64/boot/dts/allwinner/Makefile index 108f12c..c997b5c 100644 --- a/arch/arm64/boot/dts/allwinner/Makefile +++ b/arch/arm64/boot/dts/allwinner/Makefile @@ -1,4 +1,5 @@ dtb-$(CONFIG_ARCH_SUNXI) += sun50i-a64-bananapi-m64.dtb +dtb-$(CONFIG_ARCH_SUNXI) += sun50i-a64-nanopi-a64.dtb dtb-$(CONFIG_ARCH_SUNXI) += sun50i-a64-orangepi-win.dtb dtb-$(CONFIG_ARCH_SUNXI) += sun50i-a64-pine64-plus.dtb sun50i-a64-pine64.dtb dtb-$(CONFIG_ARCH_SUNXI) += sun50i-a64-sopine-baseboard.dtb diff --git a/arch/arm64/boot/dts/allwinner/sun50i-a64-nanopi-a64.dts b/arch/arm64/boot/dts/allwinner/sun50i-a64-nanopi-a64.dts new file mode 100644 index 0000000..de98da1 --- /dev/null +++ b/arch/arm64/boot/dts/allwinner/sun50i-a64-nanopi-a64.dts @@ -0,0 +1,205 @@ +/* + * Copyright (C) 2017 Jagan Teki + * + * This file is dual-licensed: you can use it either under the terms + * of the GPL or the X11 license, at your option.
