menu "Qualcomm SoC drivers"
config QCOM_COMMAND_DB
bool "Qualcomm Command DB"
depends on ARCH_QCOM || COMPILE_TEST
depends on OF_RESERVED_MEM
help
Command DB queries shared memory by key string for shared system
resources. Platform drivers that require to set state of a shared
resource on a RPM-hardened platform must use this database to get
SoC specific identifier and information for the shared resources.
config QCOM_GENI_SE
tristate "QCOM GENI Serial Engine Driver"
depends on ARCH_QCOM || COMPILE_TEST
select REGMAP_MMIO
help
This driver is used to manage Generic Interface (GENI) firmware based
Qualcomm Technologies, Inc. Universal Peripheral (QUP) Wrapper. This
driver is also used to manage the common aspects of multiple Serial
Engines present in the QUP.
config QCOM_GLINK_SSR
tristate "Qualcomm Glink SSR driver"
depends on RPMSG
depends on QCOM_RPROC_COMMON
help
Say y here to enable GLINK SSR support. The GLINK SSR driver
implements the SSR protocol for notifying the remote processor about
neighboring subsystems going up or down.
config QCOM_GSBI
tristate "QCOM General Serial Bus Interface"
depends on ARCH_QCOM
select MFD_SYSCON
help
Say y here to enable GSBI support. The GSBI provides control
functions for connecting the underlying serial UART, SPI, and I2C
devices to the output pins.
config QCOM_LLCC
tristate "Qualcomm Technologies, Inc. LLCC driver"
depends on ARCH_QCOM
help
Qualcomm Technologies, Inc. platform specific
Last Level Cache Controller(LLCC) driver. This provides interfaces
to clients that use the LLCC. Say yes here to enable LLCC slice
driver.
config QCOM_SDM845_LLCC
tristate "Qualcomm Technologies, Inc. SDM845 LLCC driver"
depends on QCOM_LLCC
help
Say yes here to enable the LLCC driver for SDM845. This provides
data required to configure LLCC so that clients can start using the
LLCC slices.
config QCOM_MDT_LOADER
tristate
select QCOM_SCM
config QCOM_PM
bool "Qualcomm Power Management"
depends on ARCH_QCOM && !ARM64
select ARM_CPU_SUSPEND
select QCOM_SCM
help
QCOM Platform specific power driver to manage cores and L2 low power
modes. It interface with various system drivers to put the cores in
low power modes.
config QCOM_QMI_HELPERS
tristate
depends on ARCH_QCOM && NET
help
Helper library for handling QMI encoded messages. QMI encoded
messages are used in communication between the majority of QRTR
clients and this helpers provide the common functionality needed for
doing this from a kernel driver.
config QCOM_RMTFS_MEM
tristate "Qualcomm Remote Filesystem memory driver"
depends on ARCH_QCOM
select QCOM_SCM
help
The Qualcomm remote filesystem memory driver is used for allocating
and exposing regions of shared memory with remote processors for the
purpose of exchanging sector-data between the remote filesystem
service and its clients.
Say y here if you intend to boot the modem remoteproc.
config QCOM_RPMH
bool "Qualcomm RPM-Hardened (RPMH) Communication"
depends on ARCH_QCOM && ARM64 && OF || COMPILE_TEST
help
Support for communication with the hardened-RPM blocks in
Qualcomm Technologies Inc (QTI) SoCs. RPMH communication uses an
internal bus to transmit state requests for shared resources. A set
of hardware components aggregate requests for these resources and
help apply the aggregated state on the resource.
config QCOM_SMEM
tristate "Qualcomm Shared Memory Manager (SMEM)"
depends on ARCH_QCOM
depends on HWSPINLOCK
help
Say y here to enable support for the Qualcomm Shared Memory Manager.
The driver provides an interface to items in a heap shared among all
processors in a Qualcomm platform.
config QCOM_SMD_RPM
tristate "Qualcomm Resource Power Manager (RPM) over SMD"
depends on ARCH_QCOM
depends on RPMSG && OF
help
If you say yes to this option, support will be included for the
Resource Power Manager system found in the Qualcomm 8974 based
devices.
This is required to access many regulators, clocks and bus
frequencies controlled by the RPM on these devices.
Say M here if you want to include support for the Qualcomm RPM as a
module. This will build a module called "qcom-smd-rpm".
config QCOM_SMEM_STATE
bool
config QCOM_SMP2P
tristate "Qualcomm Shared Memory Point to Point support"
depends on MAILBOX
depends on QCOM_SMEM
select QCOM_SMEM_STATE
help
Say yes here to support the Qualcomm Shared Memory Point to Point
protocol.
config QCOM_SMSM
tristate "Qualcomm Shared Memory State Machine"
depends on QCOM_SMEM
select QCOM_SMEM_STATE
help
Say yes here to support the Qualcomm Shared Memory State Machine.
The state machine is represented by bits in shared memory.
config QCOM_WCNSS_CTRL
tristate "Qualcomm WCNSS control driver"
depends on ARCH_QCOM
depends on RPMSG
help
Client driver for the WCNSS_CTRL SMD channel, used to download nv
firmware to a newly booted WCNSS chip.
config QCOM_APR
tristate "Qualcomm APR Bus (Asynchronous Packet Router)"
depends on ARCH_QCOM
depends on RPMSG
help
Enable APR IPC protocol support between
application processor and QDSP6. APR is
used by audio driver to configure QDSP6
ASM, ADM and AFE modules.
