5 menu "Qualcomm SoC drivers"
8 tristate "Qualcomm AOSS Driver"
9 depends on ARCH_QCOM || COMPILE_TEST
11 depends on COMMON_CLK && PM
12 select PM_GENERIC_DOMAINS
14 This driver provides the means of communicating with and controlling
15 the low-power state for resources related to the remoteproc
16 subsystems as well as controlling the debug clocks exposed by the Always On
17 Subsystem (AOSS) using Qualcomm Messaging Protocol (QMP).
19 config QCOM_COMMAND_DB
20 bool "Qualcomm Command DB"
21 depends on ARCH_QCOM || COMPILE_TEST
22 depends on OF_RESERVED_MEM
24 Command DB queries shared memory by key string for shared system
25 resources. Platform drivers that require to set state of a shared
26 resource on a RPM-hardened platform must use this database to get
27 SoC specific identifier and information for the shared resources.
30 tristate "QCOM GENI Serial Engine Driver"
31 depends on ARCH_QCOM || COMPILE_TEST
33 This driver is used to manage Generic Interface (GENI) firmware based
34 Qualcomm Technologies, Inc. Universal Peripheral (QUP) Wrapper. This
35 driver is also used to manage the common aspects of multiple Serial
36 Engines present in the QUP.
39 tristate "Qualcomm Glink SSR driver"
41 depends on QCOM_RPROC_COMMON
43 Say y here to enable GLINK SSR support. The GLINK SSR driver
44 implements the SSR protocol for notifying the remote processor about
45 neighboring subsystems going up or down.
48 tristate "QCOM General Serial Bus Interface"
49 depends on ARCH_QCOM || COMPILE_TEST
52 Say y here to enable GSBI support. The GSBI provides control
53 functions for connecting the underlying serial UART, SPI, and I2C
54 devices to the output pins.
57 tristate "Qualcomm Technologies, Inc. LLCC driver"
58 depends on ARCH_QCOM || COMPILE_TEST
60 Qualcomm Technologies, Inc. platform specific
61 Last Level Cache Controller(LLCC) driver. This provides interfaces
62 to clients that use the LLCC. Say yes here to enable LLCC slice
65 config QCOM_SDM845_LLCC
66 tristate "Qualcomm Technologies, Inc. SDM845 LLCC driver"
69 Say yes here to enable the LLCC driver for SDM845. This provides
70 data required to configure LLCC so that clients can start using the
73 config QCOM_MDT_LOADER
78 bool "Qualcomm Power Management"
79 depends on ARCH_QCOM && !ARM64
80 select ARM_CPU_SUSPEND
83 QCOM Platform specific power driver to manage cores and L2 low power
84 modes. It interface with various system drivers to put the cores in
87 config QCOM_QMI_HELPERS
89 depends on ARCH_QCOM || COMPILE_TEST
93 tristate "Qualcomm Remote Filesystem memory driver"
97 The Qualcomm remote filesystem memory driver is used for allocating
98 and exposing regions of shared memory with remote processors for the
99 purpose of exchanging sector-data between the remote filesystem
100 service and its clients.
102 Say y here if you intend to boot the modem remoteproc.
105 bool "Qualcomm RPM-Hardened (RPMH) Communication"
106 depends on ARCH_QCOM && ARM64 || COMPILE_TEST
108 Support for communication with the hardened-RPM blocks in
109 Qualcomm Technologies Inc (QTI) SoCs. RPMH communication uses an
110 internal bus to transmit state requests for shared resources. A set
111 of hardware components aggregate requests for these resources and
112 help apply the aggregated state on the resource.
115 bool "Qualcomm RPMh Power domain driver"
116 depends on QCOM_RPMH && QCOM_COMMAND_DB
118 QCOM RPMh Power domain driver to support power-domains with
119 performance states. The driver communicates a performance state
120 value to RPMh which then translates it into corresponding voltage
121 for the voltage rail.
124 bool "Qualcomm RPM Power domain driver"
125 depends on QCOM_SMD_RPM=y
127 QCOM RPM Power domain driver to support power-domains with
128 performance states. The driver communicates a performance state
129 value to RPM which then translates it into corresponding voltage
130 for the voltage rail.
133 tristate "Qualcomm Shared Memory Manager (SMEM)"
134 depends on ARCH_QCOM || COMPILE_TEST
135 depends on HWSPINLOCK
137 Say y here to enable support for the Qualcomm Shared Memory Manager.
138 The driver provides an interface to items in a heap shared among all
139 processors in a Qualcomm platform.
142 tristate "Qualcomm Resource Power Manager (RPM) over SMD"
143 depends on ARCH_QCOM || COMPILE_TEST
146 If you say yes to this option, support will be included for the
147 Resource Power Manager system found in the Qualcomm 8974 based
150 This is required to access many regulators, clocks and bus
151 frequencies controlled by the RPM on these devices.
153 Say M here if you want to include support for the Qualcomm RPM as a
154 module. This will build a module called "qcom-smd-rpm".
156 config QCOM_SMEM_STATE
160 tristate "Qualcomm Shared Memory Point to Point support"
163 select QCOM_SMEM_STATE
166 Say yes here to support the Qualcomm Shared Memory Point to Point
170 tristate "Qualcomm Shared Memory State Machine"
172 select QCOM_SMEM_STATE
175 Say yes here to support the Qualcomm Shared Memory State Machine.
176 The state machine is represented by bits in shared memory.
179 tristate "Qualcomm socinfo driver"
183 Say yes here to support the Qualcomm socinfo driver, providing
184 information about the SoC to user space.
