# RPMSG always gets selected by whoever wants it
config RPMSG
tristate
config RPMSG_CHAR
tristate "RPMSG device interface"
depends on RPMSG
depends on NET
help
Say Y here to export rpmsg endpoints as device files, usually found
in /dev. They make it possible for user-space programs to send and
receive rpmsg packets.

config RPMSG_QCOM_GLINK_RPM
tristate "Qualcomm RPM Glink driver"
select RPMSG_QCOM_GLINK_NATIVE
depends on HAS_IOMEM
depends on MAILBOX
help
Say y here to enable support for the GLINK RPM communication driver,
which serves as a channel for communication with the RPM in GLINK
enabled systems.
config RPMSG_QCOM_GLINK_SMEM
tristate "Qualcomm SMEM Glink driver"
select RPMSG_QCOM_GLINK_NATIVE
depends on MAILBOX
depends on QCOM_SMEM
help
Say y here to enable support for the GLINK SMEM communication driver,
which provides support for using the GLINK communication protocol
over SMEM.
config RPMSG_QCOM_GLINK_SPSS
tristate "Qualcomm SPSS Glink driver"
select RPMSG_QCOM_GLINK_NATIVE
depends on MAILBOX
depends on QCOM_SMEM
select QSEE_IPC_IRQ
help
Say y here to enable support for the GLINK SPSS communication driver,
which provides support for using the GLINK communication protocol
over SMEM. This protocol maps the smem and then shares the mapped
region with the remote proc by writing the smem descriptor location
and size into shared registers.
config RPMSG_QCOM_GLINK_SPI
tristate "Qualcomm SPI Glink driver"
help
Say y here to enable support for the GLINK SPI communication driver,
which provides support for using the GLINK communication protocol
over SPI. This transport performs marshaling of GLINK commands and
data to the appropriate SPI bus wire format and allows for GLINK
communication with remote subsystems that are external to the SoC.
config RPMSG_QCOM_SMD
tristate "Qualcomm Shared Memory Driver (SMD)"
depends on QCOM_SMEM
select RPMSG
help
Say y here to enable support for the Qualcomm Shared Memory Driver
providing communication channels to remote processors in Qualcomm
platforms.
config RPMSG_VIRTIO
tristate
select RPMSG
select VIRTIO
config MSM_RPM_SMD
bool "RPM driver using SMD protocol"
help
RPM is the dedicated hardware engine for managing shared SoC
resources. This config adds driver support for using SMD as a
transport layer communication with RPM hardware. It also selects
the MSM_MPM config that programs the MPM module to monitor interrupts
during sleep modes.
