help
Say y here to support the OMAP Hardware Spinlock device (firstly
introduced in OMAP4).
If unsure, say N.
config HWSPINLOCK_QCOM
tristate "Qualcomm Hardware Spinlock device"

help
Say y here to support the Qualcomm Hardware Mutex functionality, which
provides a synchronisation mechanism for the various processors on
the SoC.
If unsure, say N.
config HWSPINLOCK_SIRF
tristate "SIRF Hardware Spinlock device"
depends on HWSPINLOCK
depends on ARCH_SIRF
help
Say y here to support the SIRF Hardware Spinlock device, which
provides a synchronisation mechanism for the various processors
on the SoC.
It's safe to say n here if you're not interested in SIRF hardware
spinlock or just want a bare minimum kernel.
config HWSPINLOCK_SPRD
tristate "SPRD Hardware Spinlock device"
depends on ARCH_SPRD
depends on HWSPINLOCK
help
Say y here to support the SPRD Hardware Spinlock device.
If unsure, say N.
config HWSPINLOCK_STM32
tristate "STM32 Hardware Spinlock device"
depends on MACH_STM32MP157
depends on HWSPINLOCK
help
Say y here to support the STM32 Hardware Spinlock device.
If unsure, say N.
config HSEM_U8500
tristate "STE Hardware Semaphore functionality"
depends on HWSPINLOCK
depends on ARCH_U8500
help
Say y here to support the STE Hardware Semaphore functionality, which
provides a synchronisation mechanism for the various processor on the
SoC.
If unsure, say N.
