Linus Torvalds 399eb9b6cb ARM: SoC driver updates for v5.4 
The branch contains driver changes that are tightly
 connected to SoC specific code. Aside from smaller
 cleanups and bug fixes, here is a list of the notable
 changes.
 
 New device drivers:
 
 - The Turris Mox router has a new "moxtet" bus driver
   for its on-board pluggable extension bus. The
   same platform also gains a firmware driver.
 
 - The Samsung Exynos family gains a new Chipid driver
   exporting using the soc device sysfs interface
 
 - A similar socinfo driver for Qualcomm Snapdragon
   chips.
 
 - A firmware driver for the NXP i.MX DSP IPC protocol
   using shared memory and a mailbox
 
 Other changes:
 
 - The i.MX reset controller driver now supports the
   NXP i.MX8MM chip
 
 - Amlogic SoC specific drivers gain support for
   the S905X3 and A311D chips
 
 - A rework of the TI Davinci framebuffer driver to
   allow important cleanups in the platform code
 
 - A couple of device drivers for removed ARM SoC
   platforms are removed. Most of the removals were
   picked up by other maintainers, this contains
   whatever was left.

config ARM_SCMI_PROTOCOL
bool "ARM System Control and Management Interface (SCMI) Message Protocol"
depends on ARM || ARM64 || COMPILE_TEST
depends on MAILBOX
help
ARM System Control and Management Interface (SCMI) protocol is a
set of operating system-independent software interfaces that are
used in system management. SCMI is extensible and currently provides
interfaces for: Discovery and self-description of the interfaces
it supports, Power domain management which is the ability to place
a given device or domain into the various power-saving states that
it supports, Performance management which is the ability to control
the performance of a domain that is composed of compute engines
such as application processors and other accelerators, Clock
management which is the ability to set and inquire rates on platform
managed clocks and Sensor management which is the ability to read
sensor data, and be notified of sensor value.
This protocol library provides interface for all the client drivers
making use of the features offered by the SCMI.
config ARM_SCMI_POWER_DOMAIN
tristate "SCMI power domain driver"
depends on ARM_SCMI_PROTOCOL || (COMPILE_TEST && OF)
default y
select PM_GENERIC_DOMAINS if PM
help
This enables support for the SCMI power domains which can be
enabled or disabled via the SCP firmware
This driver can also be built as a module. If so, the module
will be called scmi_pm_domain. Note this may needed early in boot
before rootfs may be available.
config ARM_SCPI_PROTOCOL
tristate "ARM System Control and Power Interface (SCPI) Message Protocol"
depends on ARM || ARM64 || COMPILE_TEST
depends on MAILBOX
help
System Control and Power Interface (SCPI) Message Protocol is
defined for the purpose of communication between the Application
Cores(AP) and the System Control Processor(SCP). The MHU peripheral
provides a mechanism for inter-processor communication between SCP
and AP.
SCP controls most of the power managament on the Application
Processors. It offers control and management of: the core/cluster
power states, various power domain DVFS including the core/cluster,
certain system clocks configuration, thermal sensors and many
others.
This protocol library provides interface for all the client drivers
making use of the features offered by the SCP.
config ARM_SCPI_POWER_DOMAIN
tristate "SCPI power domain driver"
depends on ARM_SCPI_PROTOCOL || (COMPILE_TEST && OF)
default y
select PM_GENERIC_DOMAINS if PM
help
This enables support for the SCPI power domains which can be
enabled or disabled via the SCP firmware
config ARM_SDE_INTERFACE
bool "ARM Software Delegated Exception Interface (SDEI)"
depends on ARM64
help
The Software Delegated Exception Interface (SDEI) is an ARM
standard for registering callbacks from the platform firmware
into the OS. This is typically used to implement RAS notifications.
config EDD
tristate "BIOS Enhanced Disk Drive calls determine boot disk"
depends on X86
help
Say Y or M here if you want to enable BIOS Enhanced Disk Drive
Services real mode BIOS calls to determine which disk
BIOS tries boot from. This information is then exported via sysfs.
This option is experimental and is known to fail to boot on some
obscure configurations. Most disk controller BIOS vendors do
not yet implement this feature.
config EDD_OFF
bool "Sets default behavior for EDD detection to off"
depends on EDD
default n
help
Say Y if you want EDD disabled by default, even though it is compiled into the
kernel. Say N if you want EDD enabled by default. EDD can be dynamically set
using the kernel parameter 'edd={on|skipmbr|off}'.
config FIRMWARE_MEMMAP
bool "Add firmware-provided memory map to sysfs" if EXPERT
default X86
help
Add the firmware-provided (unmodified) memory map to /sys/firmware/memmap.
That memory map is used for example by kexec to set up parameter area
for the next kernel, but can also be used for debugging purposes.
See also Documentation/ABI/testing/sysfs-firmware-memmap.
config EFI_PCDP
bool "Console device selection via EFI PCDP or HCDP table"
depends on ACPI && EFI && IA64
default y if IA64
help
If your firmware supplies the PCDP table, and you want to
automatically use the primary console device it describes
as the Linux console, say Y here.
If your firmware supplies the HCDP table, and you want to
use the first serial port it describes as the Linux console,
say Y here. If your EFI ConOut path contains only a UART
device, it will become the console automatically. Otherwise,
you must specify the "console=hcdp" kernel boot argument.
Neither the PCDP nor the HCDP affects naming of serial devices,
so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
on how the driver discovers devices.
You must also enable the appropriate drivers (serial, VGA, etc.)
See DIG64_HCDPv20_042804.pdf available from
<http://www.dig64.org/specifications/>
config DMIID
bool "Export DMI identification via sysfs to userspace"
depends on DMI

bool
config ISCSI_IBFT_FIND
bool "iSCSI Boot Firmware Table Attributes"
depends on X86 && ISCSI_IBFT
default n
help
This option enables the kernel to find the region of memory
in which the ISCSI Boot Firmware Table (iBFT) resides. This
is necessary for iSCSI Boot Firmware Table Attributes module to work
properly.
config ISCSI_IBFT
tristate "iSCSI Boot Firmware Table Attributes module"
select ISCSI_BOOT_SYSFS
select ISCSI_IBFT_FIND if X86
depends on ACPI && SCSI && SCSI_LOWLEVEL
default n
help
This option enables support for detection and exposing of iSCSI
Boot Firmware Table (iBFT) via sysfs to userspace. If you wish to
detect iSCSI boot parameters dynamically during system boot, say Y.
Otherwise, say N.
config RASPBERRYPI_FIRMWARE
tristate "Raspberry Pi Firmware Driver"
depends on BCM2835_MBOX
help

and manages secure monitor call to communicate with secure monitor
software at secure monitor exception level.
Say Y here if you want Stratix10 service layer support.
config QCOM_SCM
bool
depends on ARM || ARM64
select RESET_CONTROLLER
config QCOM_SCM_32
def_bool y
depends on QCOM_SCM && ARM
config QCOM_SCM_64
def_bool y

compute systems such as ARM, DSP etc with the system controller in
complex System on Chip(SoC) such as those found on certain keystone
generation SoC from TI.
System controller provides various facilities including power
management function support.
This protocol library is used by client drivers to use the features
provided by the system controller.
config TRUSTED_FOUNDATIONS
bool "Trusted Foundations secure monitor support"
depends on ARM && CPU_V7
help
Some devices (including most early Tegra-based consumer devices on
the market) are booted with the Trusted Foundations secure monitor
active, requiring some core operations to be performed by the secure
monitor instead of the kernel.
This option allows the kernel to invoke the secure monitor whenever
required on devices using Trusted Foundations. See the functions and
comments in linux/firmware/trusted_foundations.h or the device tree
bindings for "tlm,trusted-foundations" for details on how to use it.
Choose N if you don't know what this is about.
