Amlogic Meson8 and Meson8b SRAM for smp bringup:
|
||||
------------------------------------------------
|
||||
|
||||
Amlogic's SMP-capable SoCs use part of the sram for the bringup of the cores.
|
||||
Once the core gets powered up it executes the code that is residing at a
|
||||
specific location.
|
||||
|
||||
Therefore a reserved section sub-node has to be added to the mmio-sram
|
||||
declaration.
|
||||
|
||||
Required sub-node properties:
|
||||
- compatible : depending on the SoC this should be one of:
|
||||
"amlogic,meson8-smp-sram"
|
||||
"amlogic,meson8b-smp-sram"
|
||||
|
||||
The rest of the properties should follow the generic mmio-sram discription
|
||||
found in ../../misc/sram.txt
|
||||
|
||||
Example:
|
||||
|
||||
sram: sram@d9000000 {
|
||||
compatible = "mmio-sram";
|
||||
reg = <0xd9000000 0x20000>;
|
||||
#address-cells = <1>;
|
||||
#size-cells = <1>;
|
||||
ranges = <0 0xd9000000 0x20000>;
|
||||
|
||||
smp-sram@1ff80 {
|
||||
compatible = "amlogic,meson8b-smp-sram";

SAMSUNG Exynos SoC series PMU Registers
|

|

Properties:
|

- compatible : should contain two values. First value must be one from following list:
|
||||
- "samsung,exynos3250-pmu" - for Exynos3250 SoC,
|
||||
- "samsung,exynos4210-pmu" - for Exynos4210 SoC,
|
||||
- "samsung,exynos4412-pmu" - for Exynos4412 SoC,
|
||||
- "samsung,exynos5250-pmu" - for Exynos5250 SoC,
|
||||
- "samsung,exynos5260-pmu" - for Exynos5260 SoC.
|
||||
- "samsung,exynos5410-pmu" - for Exynos5410 SoC,
|
||||
- "samsung,exynos5420-pmu" - for Exynos5420 SoC.
|
||||
- "samsung,exynos5433-pmu" - for Exynos5433 SoC.
|
||||
- "samsung,exynos7-pmu" - for Exynos7 SoC.
|
||||
second value must be always "syscon".
|
||||
|
||||
- reg : offset and length of the register set.
|
||||
|
||||
- #clock-cells : must be <1>, since PMU requires once cell as clock specifier.
|
||||
The single specifier cell is used as index to list of clocks
|
||||
provided by PMU, which is currently:
|
||||
0 : SoC clock output (CLKOUT pin)
|
||||
|
||||
- clock-names : list of clock names for particular CLKOUT mux inputs in
|
||||
following format:
|
||||
"clkoutN", where N is a decimal number corresponding to
|
||||
CLKOUT mux control bits value for given input, e.g.
|
||||
"clkout0", "clkout7", "clkout15".
|
||||
|
||||
- clocks : list of phandles and specifiers to all input clocks listed in
|
||||
clock-names property.
|
||||
|
||||
Optional properties:
|
||||
|
||||
Some PMUs are capable of behaving as an interrupt controller (mostly
|
||||
to wake up a suspended PMU). In which case, they can have the
|
||||
following properties:
|
||||
|
||||
- interrupt-controller: indicate that said PMU is an interrupt controller
|
||||
|
||||
- #interrupt-cells: must be identical to the that of the parent interrupt
|
||||
controller.
|
||||
|
||||
|
||||
Optional nodes:
|
||||
|
||||
- nodes defining the restart and poweroff syscon children
|
||||
|
||||
|
||||
Example :
|
||||
pmu_system_controller: system-controller@10040000 {
|
||||
compatible = "samsung,exynos5250-pmu", "syscon";
|
||||
reg = <0x10040000 0x5000>;
|
||||
interrupt-controller;
|
||||
#interrupt-cells = <3>;
|
||||
interrupt-parent = <&gic>;
|
||||
#clock-cells = <1>;
|
||||
clock-names = "clkout0", "clkout1", "clkout2", "clkout3",
|
||||
"clkout4", "clkout8", "clkout9";
|
||||
clocks = <&clock CLK_OUT_DMC>, <&clock CLK_OUT_TOP>,
|
||||
<&clock CLK_OUT_LEFTBUS>, <&clock CLK_OUT_RIGHTBUS>,
|
||||
<&clock CLK_OUT_CPU>, <&clock CLK_XXTI>,
|
||||
<&clock CLK_XUSBXTI>;
|
||||
};
|
||||
|
||||
Example of clock consumer :
|
||||
|
||||
usb3503: usb3503@8 {
|
||||
/* ... */
|
||||
clock-names = "refclk";
|

Allwinner SRAM for smp bringup:
|
||||
------------------------------------------------
|
||||
|
||||
Allwinner's A80 SoC uses part of the secure sram for hotplugging of the
|
||||
primary core (cpu0). Once the core gets powered up it checks if a magic
|
||||
value is set at a specific location. If it is then the BROM will jump
|
||||
to the software entry address, instead of executing a standard boot.
|
||||
|
||||
Therefore a reserved section sub-node has to be added to the mmio-sram
|
||||
declaration.
|
||||
|
||||
Note that this is separate from the Allwinner SRAM controller found in
|
||||
../../sram/sunxi-sram.txt. This SRAM is secure only and not mappable to
|
||||
any device.
|
||||
|
||||
Also there are no "secure-only" properties. The implementation should

Renesas Bus State Controller (BSC)
|
||||
==================================
|
||||
|
||||
The Renesas Bus State Controller (BSC, sometimes called "LBSC within Bus
|
||||
Bridge", or "External Bus Interface") can be found in several Renesas ARM SoCs.
|
||||
It provides an external bus for connecting multiple external devices to the
|
||||
SoC, driving several chip select lines, for e.g. NOR FLASH, Ethernet and USB.
|
||||
|
||||
While the BSC is a fairly simple memory-mapped bus, it may be part of a PM
|
||||
domain, and may have a gateable functional clock.
|
||||
Before a device connected to the BSC can be accessed, the PM domain
|
||||
containing the BSC must be powered on, and the functional clock
|
||||
driving the BSC must be enabled.
|
||||
|
||||
The bindings for the BSC extend the bindings for "simple-pm-bus".
|
||||
|
||||
|
||||
Required properties
|
||||
- compatible: Must contain an SoC-specific value, and "renesas,bsc" and
|
||||
"simple-pm-bus" as fallbacks.
|
||||
SoC-specific values can be:
|
||||
"renesas,bsc-r8a73a4" for R-Mobile APE6 (r8a73a4)
|
||||
"renesas,bsc-sh73a0" for SH-Mobile AG5 (sh73a0)
|
||||
- #address-cells, #size-cells, ranges: Must describe the mapping between
|
||||
parent address and child address spaces.
|
||||
- reg: Must contain the base address and length to access the bus controller.
|
||||
|
||||
Optional properties:
|
||||
- interrupts: Must contain a reference to the BSC interrupt, if available.
|
||||
- clocks: Must contain a reference to the functional clock, if available.
|
||||
- power-domains: Must contain a reference to the PM domain, if available.
|
||||
|
||||
|
||||
Example:
|
||||
|
||||
bsc: bus@fec10000 {
|
||||

Simple Power-Managed Bus
|
||||
========================
|
||||
|
||||
A Simple Power-Managed Bus is a transparent bus that doesn't need a real
|
||||
driver, as it's typically initialized by the boot loader.
|
||||
|
||||
However, its bus controller is part of a PM domain, or under the control of a
|
||||
functional clock. Hence, the bus controller's PM domain and/or clock must be
|
||||
enabled for child devices connected to the bus (either on-SoC or externally)
|
||||
to function.
|
||||
|
||||
While "simple-pm-bus" follows the "simple-bus" set of properties, as specified
|
||||
in the Devicetree Specification, it is not an extension of "simple-bus".
|
||||
|
||||
|
||||
Required properties:
|
||||
- compatible: Must contain at least "simple-pm-bus".
|
||||
Must not contain "simple-bus".
|
||||
It's recommended to let this be preceded by one or more
|
||||
vendor-specific compatible values.
|
||||
- #address-cells, #size-cells, ranges: Must describe the mapping between
|
||||
parent address and child address spaces.
|
||||
|
||||
Optional platform-specific properties for clock or PM domain control (at least
|
||||
one of them is required):
|
||||
- clocks: Must contain a reference to the functional clock(s),
|
||||
- power-domains: Must contain a reference to the PM domain.
|
||||
Please refer to the binding documentation for the clock and/or PM domain
|
||||
providers for more details.
|
||||
|
||||
|
||||
Example:
|
||||
|
||||
bsc: bus@fec10000 {
|
||||
compatible = "renesas,bsc-sh73a0", "renesas,bsc",
|

EEPROMs (I2C)
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible: Must be a "<manufacturer>,<model>" pair. The following <model>
|
||||
values are supported (assuming "atmel" as manufacturer):
|
||||
|
||||
"atmel,24c00",
|
||||
"atmel,24c01",
|
||||
"atmel,24cs01",
|
||||
"atmel,24c02",
|
||||
"atmel,24cs02",
|
||||
"atmel,24mac402",
|
||||
"atmel,24mac602",
|
||||
"atmel,spd",
|
||||
"atmel,24c04",
|
||||
"atmel,24cs04",
|
||||
"atmel,24c08",
|
||||
"atmel,24cs08",
|
||||
"atmel,24c16",
|
||||
"atmel,24cs16",
|
||||
"atmel,24c32",
|
||||
"atmel,24cs32",
|
||||
"atmel,24c64",
|
||||
"atmel,24cs64",
|
||||
"atmel,24c128",
|
||||
"atmel,24c256",
|
||||
"atmel,24c512",
|
||||
"atmel,24c1024",
|
||||
"atmel,24c2048",
|
||||
|
||||
If <manufacturer> is not "atmel", then a fallback must be used
|
||||
with the same <model> and "atmel" as manufacturer.
|
||||
|
||||
Example:
|
||||
compatible = "microchip,24c128", "atmel,24c128";
|
||||
|
||||
Supported manufacturers are:
|
||||
|
||||
"catalyst",
|
||||
"microchip",
|
||||
"nxp",
|
||||
"ramtron",
|
||||
"renesas",
|
||||
"rohm",
|
||||
"st",
|
||||
|
||||
Some vendors use different model names for chips which are just
|
||||
variants of the above. Known such exceptions are listed below:
|
||||
|
||||
"nxp,se97b" - the fallback is "atmel,24c02",
|
||||
"renesas,r1ex24002" - the fallback is "atmel,24c02"
|
||||
"renesas,r1ex24016" - the fallback is "atmel,24c16"
|
||||
"renesas,r1ex24128" - the fallback is "atmel,24c128"
|
||||
"rohm,br24t01" - the fallback is "atmel,24c01"
|
||||
|
||||
- reg: The I2C address of the EEPROM.
|
||||
|
||||
Optional properties:
|
||||
|
||||
- pagesize: The length of the pagesize for writing. Please consult the
|
||||
manual of your device, that value varies a lot. A wrong value
|
||||
may result in data loss! If not specified, a safety value of
|
||||
'1' is used which will be very slow.
|
||||
|
||||
- read-only: This parameterless property disables writes to the eeprom.
|
||||
|
||||
- size: Total eeprom size in bytes.
|
||||
|
||||
- no-read-rollover: This parameterless property indicates that the
|
||||
multi-address eeprom does not automatically roll over
|
||||
reads to the next slave address. Please consult the
|
||||
manual of your device.
|
||||
|
||||
- wp-gpios: GPIO to which the write-protect pin of the chip is connected.
|
||||
|
||||
- address-width: number of address bits (one of 8, 16).
|
||||
|
||||
- num-addresses: total number of i2c slave addresses this device takes
|
||||
|
||||
Example:
|
||||
|
||||
eeprom@52 {
|
||||
compatible = "atmel,24c32";
|
||||
reg = <0x52>;
|
||||
pagesize = <32>;
|
||||
wp-gpios = <&gpio1 3 0>;
|
||||
num-addresses = <8>;

* ARM SMMUv3 Architecture Implementation
|
||||
|
||||
The SMMUv3 architecture is a significant departure from previous
|
||||
revisions, replacing the MMIO register interface with in-memory command
|
||||
and event queues and adding support for the ATS and PRI components of
|
||||
the PCIe specification.
|
||||
|
||||
** SMMUv3 required properties:
|
||||
|
||||
- compatible : Should include:
|
||||
|
||||
* "arm,smmu-v3" for any SMMUv3 compliant
|
||||
implementation. This entry should be last in the
|
||||
compatible list.
|
||||
|
||||
- reg : Base address and size of the SMMU.
|
||||
|
||||
- interrupts : Non-secure interrupt list describing the wired
|
||||
interrupt sources corresponding to entries in
|
||||
interrupt-names. If no wired interrupts are
|
||||
present then this property may be omitted.
|
||||
|
||||
- interrupt-names : When the interrupts property is present, should
|
||||
include the following:
|
||||
* "eventq" - Event Queue not empty
|
||||
* "priq" - PRI Queue not empty
|
||||
* "cmdq-sync" - CMD_SYNC complete
|
||||
* "gerror" - Global Error activated
|
||||
* "combined" - The combined interrupt is optional,
|
||||
and should only be provided if the
|
||||
hardware supports just a single,
|
||||
combined interrupt line.
|
||||
If provided, then the combined interrupt
|
||||
will be used in preference to any others.
|
||||
|
||||
- #iommu-cells : See the generic IOMMU binding described in
|
||||
devicetree/bindings/pci/pci-iommu.txt
|
||||
for details. For SMMUv3, must be 1, with each cell
|
||||
describing a single stream ID. All possible stream
|
||||
IDs which a device may emit must be described.
|
||||
|
||||
** SMMUv3 optional properties:
|
||||
|
||||
- dma-coherent : Present if DMA operations made by the SMMU (page
|
||||
table walks, stream table accesses etc) are cache
|
||||
coherent with the CPU.
|
||||
|
||||
NOTE: this only applies to the SMMU itself, not
|
||||
masters connected upstream of the SMMU.
|
||||
|
||||
- msi-parent : See the generic MSI binding described in
|
||||
devicetree/bindings/interrupt-controller/msi.txt
|
||||
for a description of the msi-parent property.
|
||||
|
||||
- hisilicon,broken-prefetch-cmd
|
||||
: Avoid sending CMD_PREFETCH_* commands to the SMMU.
|
||||
|
||||
- cavium,cn9900-broken-page1-regspace
|
||||
: Replaces all page 1 offsets used for EVTQ_PROD/CONS,
|
||||
PRIQ_PROD/CONS register access with page 0 offsets.
|
||||
Set for Cavium ThunderX2 silicon that doesn't support
|
||||
SMMU page1 register space.
|
||||

* ARM System MMU Architecture Implementation
|
||||
|
||||
ARM SoCs may contain an implementation of the ARM System Memory
|
||||
Management Unit Architecture, which can be used to provide 1 or 2 stages
|
||||
of address translation to bus masters external to the CPU.
|
||||
|
||||
The SMMU may also raise interrupts in response to various fault
|
||||
conditions.
|
||||
|
||||
** System MMU required properties:
|
||||
|
||||
- compatible : Should be one of:
|
||||
|
||||
"arm,smmu-v1"
|
||||
"arm,smmu-v2"
|
||||
"arm,mmu-400"
|
||||
"arm,mmu-401"
|
||||
"arm,mmu-500"
|
||||
"cavium,smmu-v2"
|
||||
"qcom,smmu-v2"
|
||||
|
||||
depending on the particular implementation and/or the
|
||||
version of the architecture implemented.
|
||||
|
||||
Qcom SoCs must contain, as below, SoC-specific compatibles
|
||||
along with "qcom,smmu-v2":
|
||||
"qcom,msm8996-smmu-v2", "qcom,smmu-v2",
|
||||
"qcom,sdm845-smmu-v2", "qcom,smmu-v2".
|
||||
|
||||
Qcom SoCs implementing "arm,mmu-500" must also include,
|
||||
as below, SoC-specific compatibles:
|
||||
"qcom,sdm845-smmu-500", "arm,mmu-500"
|
||||
|
||||
- reg : Base address and size of the SMMU.
|
||||
|
||||
- #global-interrupts : The number of global interrupts exposed by the
|
||||
device.
|
||||
|
||||
- interrupts : Interrupt list, with the first #global-irqs entries
|
||||
corresponding to the global interrupts and any
|
||||
following entries corresponding to context interrupts,
|
||||
specified in order of their indexing by the SMMU.
|
||||
|
||||
For SMMUv2 implementations, there must be exactly one
|
||||
interrupt per context bank. In the case of a single,
|
||||
combined interrupt, it must be listed multiple times.
|
||||
|
||||
- #iommu-cells : See Documentation/devicetree/bindings/iommu/iommu.txt
|
||||
for details. With a value of 1, each IOMMU specifier
|
||||
represents a distinct stream ID emitted by that device
|
||||
into the relevant SMMU.
|
||||
|
||||
SMMUs with stream matching support and complex masters
|
||||
may use a value of 2, where the second cell of the
|
||||
IOMMU specifier represents an SMR mask to combine with
|
||||
the ID in the first cell. Care must be taken to ensure
|
||||
the set of matched IDs does not result in conflicts.
|
||||
|
||||
** System MMU optional properties:
|
||||
|
||||
- dma-coherent : Present if page table walks made by the SMMU are
|
||||
cache coherent with the CPU.
|
||||
|
||||
NOTE: this only applies to the SMMU itself, not
|
||||
masters connected upstream of the SMMU.
|
||||
|
||||
- calxeda,smmu-secure-config-access : Enable proper handling of buggy
|
||||
implementations that always use secure access to
|
||||
SMMU configuration registers. In this case non-secure
|
||||
aliases of secure registers have to be used during
|
||||
SMMU configuration.
|
||||
|
||||
- stream-match-mask : For SMMUs supporting stream matching and using
|
||||
#iommu-cells = <1>, specifies a mask of bits to ignore
|
||||
when matching stream IDs (e.g. this may be programmed
|
||||
into the SMRn.MASK field of every stream match register
|
||||
used). For cases where it is desirable to ignore some
|
||||
portion of every Stream ID (e.g. for certain MMU-500
|
||||
configurations given globally unique input IDs). This
|
||||
property is not valid for SMMUs using stream indexing,
|
||||
or using stream matching with #iommu-cells = <2>, and
|
||||
may be ignored if present in such cases.
|
||||
|
||||
- clock-names: List of the names of clocks input to the device. The
|
||||
required list depends on particular implementation and
|
||||
is as follows:
|
||||
- for "qcom,smmu-v2":
|
||||
- "bus": clock required for downstream bus access and
|
||||
for the smmu ptw,
|
||||
- "iface": clock required to access smmu's registers
|
||||
through the TCU's programming interface.
|
||||
- unspecified for other implementations.
|
||||
|
||||
- clocks: Specifiers for all clocks listed in the clock-names property,
|
||||
as per generic clock bindings.
|
||||
|
||||
- power-domains: Specifiers for power domains required to be powered on for
|
||||
the SMMU to operate, as per generic power domain bindings.
|
||||
|
||||
** Deprecated properties:
|
||||
|
||||
- mmu-masters (deprecated in favour of the generic "iommus" binding) :
|
||||
A list of phandles to device nodes representing bus
|
||||
masters for which the SMMU can provide a translation
|
||||
and their corresponding Stream IDs. Each device node
|
||||
linked from this list must have a "#stream-id-cells"
|
||||
property, indicating the number of Stream ID
|
||||
arguments associated with its phandle.

Samsung Exynos IOMMU H/W, System MMU (System Memory Management Unit)
|
||||
|
||||
Samsung's Exynos architecture contains System MMUs that enables scattered
|
||||
physical memory chunks visible as a contiguous region to DMA-capable peripheral
|
||||
devices like MFC, FIMC, FIMD, GScaler, FIMC-IS and so forth.
|
||||
|
||||
System MMU is an IOMMU and supports identical translation table format to
|
||||
ARMv7 translation tables with minimum set of page properties including access
|
||||
permissions, shareability and security protection. In addition, System MMU has
|
||||
another capabilities like L2 TLB or block-fetch buffers to minimize translation
|
||||
latency.
|
||||
|
||||
System MMUs are in many to one relation with peripheral devices, i.e. single
|
||||
peripheral device might have multiple System MMUs (usually one for each bus
|
||||
master), but one System MMU can handle transactions from only one peripheral
|
||||
device. The relation between a System MMU and the peripheral device needs to be
|
||||
defined in device node of the peripheral device.
|
||||
|
||||
MFC in all Exynos SoCs and FIMD, M2M Scalers and G2D in Exynos5420 has 2 System
|
||||
MMUs.
|
||||
* MFC has one System MMU on its left and right bus.
|
||||
* FIMD in Exynos5420 has one System MMU for window 0 and 4, the other system MMU
|
||||
for window 1, 2 and 3.
|
||||
* M2M Scalers and G2D in Exynos5420 has one System MMU on the read channel and
|
||||
the other System MMU on the write channel.
|
||||
|
||||
For information on assigning System MMU controller to its peripheral devices,
|
||||
see generic IOMMU bindings.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be "samsung,exynos-sysmmu"
|
||||
- reg: A tuple of base address and size of System MMU registers.
|
||||
- #iommu-cells: Should be <0>.
|
||||
- interrupts: An interrupt specifier for interrupt signal of System MMU,
|
||||
according to the format defined by a particular interrupt
|
||||
controller.
|
||||
- clock-names: Should be "sysmmu" or a pair of "aclk" and "pclk" to gate
|
||||
SYSMMU core clocks.
|
||||
Optional "master" if the clock to the System MMU is gated by
|
||||
another gate clock other core (usually main gate clock
|
||||
of peripheral device this SYSMMU belongs to).
|
||||
- clocks: Phandles for respective clocks described by clock-names.
|
||||
- power-domains: Required if the System MMU is needed to gate its power.
|
||||

System MMUs are in many to one relation with peripheral devices, i.e. single
|
||||
peripheral device might have multiple System MMUs (usually one for each bus
|
||||
master), but one System MMU can handle transactions from only one peripheral
|
||||
device. The relation between a System MMU and the peripheral device needs to be
|
||||
defined in device node of the peripheral device.
|
||||
|
||||
MFC in all Exynos SoCs and FIMD, M2M Scalers and G2D in Exynos5420 has 2 System
|
||||
MMUs.
|
||||
* MFC has one System MMU on its left and right bus.
|
||||
* FIMD in Exynos5420 has one System MMU for window 0 and 4, the other system MMU
|
||||
for window 1, 2 and 3.
|
||||
* M2M Scalers and G2D in Exynos5420 has one System MMU on the read channel and
|
||||
the other System MMU on the write channel.
|
||||
|
||||
For information on assigning System MMU controller to its peripheral devices,
|
||||
see generic IOMMU bindings.
