It uses single core Cortex-A7, doesn't have SDU or local (TWD) +timer. It was also stripped out of independent SPI controller and 2 +GMACs. + +DTS for Tenda AC9 isn't completed yet. It misses e.g. switch entry (we +still need some bgmac/b53 fixes) and probably some clocks. It adds +support for basic features however and can be improved later. + +Signed-off-by: Rafał Miłecki <zajec5@gmail.com> +--- + MAINTAINERS | 2 + + arch/arm/boot/dts/Makefile | 1 + + arch/arm/boot/dts/bcm47189-tenda-ac9.dts | 74 ++++++++++++++++ + arch/arm/boot/dts/bcm53573.dtsi | 147 +++++++++++++++++++++++++++++++ + 4 files changed, 224 insertions(+) + create mode 100644 arch/arm/boot/dts/bcm47189-tenda-ac9.dts + create mode 100644 arch/arm/boot/dts/bcm53573.dtsi + +--- a/MAINTAINERS ++++ b/MAINTAINERS +@@ -2337,6 +2337,8 @@ S: Maintained + F: arch/arm/mach-bcm/bcm_5301x.c + F: arch/arm/boot/dts/bcm5301x.dtsi + F: arch/arm/boot/dts/bcm470* ++F: arch/arm/boot/dts/bcm53573* ++F: arch/arm/boot/dts/bcm47189* + + BROADCOM BCM63XX ARM ARCHITECTURE + M: Florian Fainelli <f.fainelli@gmail.com> +--- a/arch/arm/boot/dts/Makefile ++++ b/arch/arm/boot/dts/Makefile +@@ -77,6 +77,7 @@ dtb-$(CONFIG_ARCH_BCM_5301X) += \ + bcm4709-netgear-r7000.dtb \ + bcm4709-netgear-r8000.dtb \ + bcm47094-dlink-dir-885l.dtb \ ++ bcm47189-tenda-ac9.dtb \ + bcm94708.dtb \ + bcm94709.dtb \ + bcm953012er.dtb \ +--- /dev/null ++++ b/arch/arm/boot/dts/bcm47189-tenda-ac9.dts +@@ -0,0 +1,74 @@ ++/* ++ * Copyright (C) 2016 Rafał Miłecki <rafal@milecki.pl> ++ * ++ * Licensed under the ISC license. ++ */ ++ ++/dts-v1/;
