depends on [31mCONFIG_SPI_MASTER[0m && [31mCONFIG_OF[0m
help
Say yes here to add support for the module configuration bus found
on CZ.NIC's Turris Mox. This is needed for the ability to discover
the order in which the modules are connected and to get/set some of
their settings. For example the GPIOs on Mox [31mCONFIG_SFP[0m module are
configured through this bus.

config [31mCONFIG_MIPS_CDMM[0m
bool "MIPS Common Device Memory Map (CDMM) Driver"
depends on [31mCONFIG_CPU_MIPSR2[0m
help
Driver needed for the [31mCONFIG_MIPS[0m Common Device Memory Map bus in [31mCONFIG_MIPS[0m
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 [31mCONFIG_SIMPLE_PM_BUS[0m
tristate "Simple Power-Managed Bus Driver"
depends on [31mCONFIG_OF[0m && [31mCONFIG_PM[0m
help
Driver for transparent busses that don't need a real driver, but
where the bus controller is part of a [31mCONFIG_PM[0m domain, or under the control
of a functional clock, and thus relies on runtime [31mCONFIG_PM[0m for managing
this [31mCONFIG_PM[0m 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 [31mCONFIG_ARM[0m SoCs.

Say y here to enable support for Allwinner A64 DE2 bus driver. It's
mostly transparent, but a [31mCONFIG_SRAM[0m region needs to be claimed in the [31mCONFIG_SRAM[0m
controller to make the all blocks in the DE2 part accessible.
