CCI-400 supports counting events related to the connected slave/master interfaces. config ARM_CCI400_PORT_CTRL bool depends on ARM && OF && CPU_V7 select ARM_CCI400_COMMON help Low level power management driver for CCI400 cache coherent interconnect for ARM platforms. config ARM_CCI5xx_PMU bool "ARM CCI-500/CCI-550 PMU support" depends on (ARM && CPU_V7) || ARM64 depends on PERF_EVENTS select ARM_CCI_PMU help Support for PMU events monitoring on the ARM CCI-500/CCI-550 cache coherent interconnects. Both of them provide 8 independent event counters, which can count events pertaining to the slave/master interfaces as well as the internal events to the CCI. If unsure, say Y config ARM_CCN tristate "ARM CCN driver support" depends on ARM || ARM64 depends on PERF_EVENTS help PMU (perf) driver supporting the ARM CCN (Cache Coherent Network) interconnect. config BRCMSTB_GISB_ARB bool "Broadcom STB GISB bus arbiter" depends on ARM || ARM64 || MIPS default ARCH_BRCMSTB || BMIPS_GENERIC help Driver for the Broadcom Set Top Box System-on-a-chip internal bus arbiter. This driver provides timeout and target abort error handling and internal bus master decoding. config IMX_WEIM bool "Freescale EIM DRIVER" depends on ARCH_MXC help Driver for i.MX WEIM controller. The WEIM(Wireless External Interface Module) works like a bus. You can attach many different devices on it, such as NOR, onenand. config MIPS_CDMM bool "MIPS Common Device Memory Map (CDMM) Driver" depends on CPU_MIPSR2 help Driver needed for the MIPS Common Device Memory Map bus in MIPS cores. This bus is for per-CPU tightly coupled devices such as the Fast Debug Channel (FDC). For this to work, either your bootloader needs to enable the CDMM region at an unused physical address on the boot CPU, or else your platform code needs to implement mips_cdmm_phys_base() (see asm/cdmm.h). config MVEBU_MBUS bool depends on PLAT_ORION help Driver needed for the MBus configuration on Marvell EBU SoCs (Kirkwood, Dove, Orion5x, MV78XX0 and Armada 370/XP). config OMAP_INTERCONNECT tristate "OMAP INTERCONNECT DRIVER" depends on ARCH_OMAP2PLUS help Driver to enable OMAP interconnect error handling driver. config OMAP_OCP2SCP tristate "OMAP OCP2SCP DRIVER" depends on ARCH_OMAP2PLUS help Driver to enable ocp2scp module which transforms ocp interface protocol to scp protocol. In OMAP4, USB PHY is connected via OCP2SCP and in OMAP5, both USB PHY and SATA PHY is connected via OCP2SCP. config QCOM_EBI2 bool "Qualcomm External Bus Interface 2 (EBI2)" depends on HAS_IOMEM depends on ARCH_QCOM || COMPILE_TEST default ARCH_QCOM help Say y here to enable support for the Qualcomm External Bus Interface 2, which can be used to connect things like NAND Flash, SRAM, ethernet adapters, FPGAs and LCD displays. config SIMPLE_PM_BUS bool "Simple Power-Managed Bus Driver" depends on OF && PM help Driver for transparent busses that don't need a real driver, but where the bus controller is part of a PM domain, or under the control of a functional clock, and thus relies on runtime PM for managing this PM domain and/or clock. An example of such a bus controller is the Renesas Bus State Controller (BSC, sometimes called "LBSC within Bus Bridge", or "External Bus Interface") as found on several Renesas ARM SoCs. config SUNXI_RSB tristate "Allwinner sunXi Reduced Serial Bus Driver" default MACH_SUN8I || MACH_SUN9I || ARM64 depends on ARCH_SUNXI select REGMAP help Say y here to enable support for Allwinner's Reduced Serial Bus (RSB) support. This controller is responsible for communicating with various RSB based devices, such as AXP223, AXP8XX PMICs, and AC100/AC200 ICs. config TEGRA_ACONNECT tristate "Tegra ACONNECT Bus Driver" depends on ARCH_TEGRA_210_SOC depends on OF && PM select PM_CLK help Driver for the Tegra ACONNECT bus which is used to interface with the devices inside the Audio Processing Engine (APE) for Tegra210. config TEGRA_GMI tristate "Tegra Generic Memory Interface bus driver" depends on ARCH_TEGRA help Driver for the Tegra Generic Memory Interface bus which can be used to attach devices such as NOR, UART, FPGA and more. config UNIPHIER_SYSTEM_BUS tristate "UniPhier System Bus driver" depends on ARCH_UNIPHIER && OF default y help Support for UniPhier System Bus, a simple external bus. This is needed to use on-board devices connected to UniPhier SoCs. config VEXPRESS_CONFIG bool "Versatile Express configuration bus" default y if ARCH_VEXPRESS depends on ARM || ARM64 depends on OF select REGMAP help Platform configuration infrastructure for the ARM Ltd. Versatile Express. config DA8XX_MSTPRI bool "TI da8xx master peripheral priority driver" depends on ARCH_DAVINCI_DA8XX help Driver for Texas Instruments da8xx master peripheral priority configuration. Allows to adjust the priorities of all master peripherals. endmenu |
