Oops, sorry about that. I have fixed up the merge resolution for today
so that file starts like this:

#
# Bus Devices
#

menu "Bus devices"

config ARM_CCI
bool

config ARM_CCI400_COMMON
bool
select ARM_CCI

config ARM_CCI400_PMU
bool "ARM CCI400 PMU support"
default y
depends on ARM || ARM64
depends on HW_PERF_EVENTS
select ARM_CCI400_COMMON
help
Support for PMU events monitoring on the ARM CCI cache coherent
interconnect.

If unsure, say Y

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_CCN
