This patch series adds Broadcom North Star 2 (NS2) SoC support. NS2 is an ARMv8 based SoC and under the Broadcom iProc family. Sorry for tying this with the Broadcom iProc PCIe driver fixes for ARM64. I have to tie them together because iProc PCIe support is enabled by default when ARCH_BCM_IPROC is enabled. Without the fixes in the iProc PCIe driver, enabling CONFIG_ARCH_BCM_IPROC would break the build for arm64 defconfig. Let me know if there's a better way to handle this. This patch series is generated based on v4.2-rc2 and tested on Broadcom NS2 SVK Code available on GITHUB: https://github.com/Broadcom/arm64-linux.git branch is ns2-core-v3 Changes from V2: - Drop hardcoded earlycon kernel command line paramter in NS2 SVK dts file because 1) earlycon is a debugging feature that can be enabled in the bootloader and should not be enabled by default in the board dts file and 2) of_earlycon should be used and support should be added to 8250 DW driver Changes from V1: - Took Arnd's advice to tweak the location of struct pci_sys_data within struct iproc_pcie. This helps to get rid of most of the CONFIG_ARM wrap in iProc PCIe core driver - Use stdout-path and alias for serial console in NS2 SVK dts - Add all 4 CPU descriptions in NS2 dtsi - Remove "clock-frequency" property in the armv8 timer node so timer frequency can be determined based on readings from CNTFRQ_EL0 - Remove config flag ARCH_BCM_NS2. Leave only ARCH_BCM_IPROC for all Broadcom arm64 SoCs as advised Ray Jui (4): PCI: iproc: enable arm64 support for iProc PCIe PCI: iproc: Fix ARM64 dependency in Kconfig arm64: Add Broadcom iProc family support arm64: dts: Add Broadcom North Star 2 support Documentation/devicetree/bindings/arm/bcm/ns2.txt | 9 ++ arch/arm64/Kconfig | 5 + arch/arm64/boot/dts/Makefile | 1 + arch/arm64/boot/dts/broadcom/Makefile | 5 + arch/arm64/boot/dts/broadcom/ns2-svk.dts | 59 +++++++++++ arch/arm64/boot/dts/broadcom/ns2.dtsi | 118 +++++++++++++++++++++ arch/arm64/configs/defconfig | 2 + drivers/pci/host/Kconfig | 2 +- drivers/pci/host/pcie-iproc.c | 15 +-- drivers/pci/host/pcie-iproc.h | 8 +- 10 files changed, 210 insertions(+), 14 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/bcm/ns2.txt create mode 100644 arch/arm64/boot/dts/broadcom/Makefile create mode 100644 arch/arm64/boot/dts/broadcom/ns2-svk.dts create mode 100644 arch/arm64/boot/dts/broadcom/ns2.dtsi -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
