Create a bg_com_dev device node for user space communication.
Single user space client can open device node for communication
from hardware. Hardware will provide access to read
registers and read/write AHB memory in the device.
config MSM_BGRSB
bool "Provide support for rsb events on Blackghost chipset"
depends on MSM_GLINK
help
BGRSB communicates to BG over Glink for RSB configuration and
enable/disable on device power state change. It enables/disables
the regulator specific to RSB. Sends the side band events generated
by BG to input framework.
config MSM_PIL_SSR_BG
tristate "MSM Subsystem Blackghost(BG) Support"
depends on MSM_PIL && MSM_SUBSYSTEM_RESTART
help
Support for booting and shutting down Blackghost(BG) SOC which is
an external SOC. This driver communicates with Blackghost(BG) SOC
via pair of IPC GPIOs for inward and outward signals between MSM
and Blackghost(BG) SOC.
config MSM_BGCOM
bool "Provide APIs to communicate with Blackghost chipset"
help
BGCOM is a thin layer above SPI. It is used whithin a SoC for
communication between G-Link/bg_com_dev and BG processor over SPI.
This handle the interrupts raised by BG and notify the G-link with
interrupt event and event data.

config BIG_CLUSTER_MIN_FREQ_ADJUST
bool "Adjust BIG cluster min frequency based on power collapse state"
default n
help
This driver is used to set the floor of the min frequency of big cluster
to the user specified value when the cluster is not power collapsed. When
the cluster is power collpsed it resets the value to physical limits.
