NVIDIA Tegra Boot and Power Management Processor (BPMP)
|
||||
|
||||
The BPMP is a specific processor in Tegra chip, which is designed for
|
||||
booting process handling and offloading the power management, clock
|
||||
management, and reset control tasks from the CPU. The binding document
|
||||
defines the resources that would be used by the BPMP firmware driver,
|
||||
which can create the interprocessor communication (IPC) between the CPU
|
||||
and BPMP.
|
||||
|
||||
Required properties:
|
||||
- name : Should be bpmp
|
||||
- compatible
|
||||
Array of strings
|
||||
One of:
|
||||
- "nvidia,tegra186-bpmp"
|
||||
- mboxes : The phandle of mailbox controller and the mailbox specifier.
|
||||
- shmem : List of the phandle of the TX and RX shared memory area that
|
||||
the IPC between CPU and BPMP is based on.
|
||||
- #clock-cells : Should be 1.
|
||||
- #power-domain-cells : Should be 1.
|
||||
- #reset-cells : Should be 1.
|
||||
|
||||
This node is a mailbox consumer. See the following files for details of
|
||||
the mailbox subsystem, and the specifiers implemented by the relevant
|
||||
provider(s):
|
||||
|
||||
- .../mailbox/mailbox.txt
|
||||
- .../mailbox/nvidia,tegra186-hsp.txt
|
||||
|
||||
This node is a clock, power domain, and reset provider. See the following
|
||||
files for general documentation of those features, and the specifiers
|
||||
implemented by this node:
|
||||
|
||||
- .../clock/clock-bindings.txt
|
||||
- <dt-bindings/clock/tegra186-clock.h>
|
||||
- ../power/power_domain.txt
|
||||
- <dt-bindings/power/tegra186-powergate.h>
|
||||
- .../reset/reset.txt
|
||||
- <dt-bindings/reset/tegra186-reset.h>
|
||||
|
||||
The BPMP implements some services which must be represented by separate nodes.
|
||||
For example, it can provide access to certain I2C controllers, and the I2C
|
||||
bindings represent each I2C controller as a device tree node. Such nodes should
|
||||
be nested directly inside the main BPMP node.
|
||||
|
||||
Software can determine whether a child node of the BPMP node represents a device
|
||||
by checking for a compatible property. Any node with a compatible property
|
||||
represents a device that can be instantiated. Nodes without a compatible
|
||||
property may be used to provide configuration information regarding the BPMP
|
||||
itself, although no such configuration nodes are currently defined by this
|
||||
binding.
|
||||
|
||||
The BPMP firmware defines no single global name-/numbering-space for such
|
||||
services. Put another way, the numbering scheme for I2C buses is distinct from
|
||||
the numbering scheme for any other service the BPMP may provide (e.g. a future
|
||||
hypothetical SPI bus service). As such, child device nodes will have no reg
|
||||
property, and the BPMP node will have no #address-cells or #size-cells property.
|
||||
|
||||
The shared memory bindings for BPMP
|
||||
-----------------------------------
|
||||
|
||||
The shared memory area for the IPC TX and RX between CPU and BPMP are
|
||||
predefined and work on top of sysram, which is an SRAM inside the chip.
|
||||
|
||||
See ".../sram/sram.txt" for the bindings.
|
||||
|
||||
Example:
|
||||
|
||||
hsp_top0: hsp@03c00000 {
|
||||
...
|
||||
#mbox-cells = <2>;

ranges = <0 0x0 0x0 0x30000000 0x0 0x50000>;

NVIDIA Tegra Hardware Synchronization Primitives (HSP)
|
||||
|
||||
The HSP modules are used for the processors to share resources and communicate
|
||||
together. It provides a set of hardware synchronization primitives for
|
||||
interprocessor communication. So the interprocessor communication (IPC)
|
||||
protocols can use hardware synchronization primitives, when operating between
|
||||
two processors not in an SMP relationship.
|
||||
|
||||
The features that HSP supported are shared mailboxes, shared semaphores,
|
||||
arbitrated semaphores and doorbells.
|
||||
|
||||
Required properties:
|
||||
- name : Should be hsp
|
||||
- compatible
|
||||
Array of strings.
|
||||
one of:
|
||||
- "nvidia,tegra186-hsp"
|
||||
- reg : Offset and length of the register set for the device.
|
||||
- interrupt-names
|
||||
Array of strings.
|
||||
Contains a list of names for the interrupts described by the interrupt
|
||||
property. May contain the following entries, in any order:
|
||||
- "doorbell"
|
||||
Users of this binding MUST look up entries in the interrupt property
|
||||
by name, using this interrupt-names property to do so.
|
||||
- interrupts
|
||||
Array of interrupt specifiers.
|
||||
Must contain one entry per entry in the interrupt-names property,
|
||||
in a matching order.
|
||||
- #mbox-cells : Should be 2.
|
||||
|
||||
The mbox specifier of the "mboxes" property in the client node should
|
||||
contain two data. The first one should be the HSP type and the second
|
||||
one should be the ID that the client is going to use. Those information
|
||||
can be found in the following file.
|
||||
|
||||
- <dt-bindings/mailbox/tegra186-hsp.h>.
|
||||
|
||||
Example:
|
||||
|
||||
hsp_top0: hsp@3c00000 {
|
||||
compatible = "nvidia,tegra186-hsp";
|
||||
reg = <0x0 0x03c00000 0x0 0xa0000>;
|
||||
interrupts = <GIC_SPI 176 IRQ_TYPE_LEVEL_HIGH>;
|
||||
interrupt-names = "doorbell";
|
||||
#mbox-cells = <2>;
|
||||
};
|
||||
|
||||
client {
|
||||
...

BPMP (Boot and Power Management Processor) is designed to off-loading
|

the PM functions which include clock/DVFS/thermal/power from the CPU.
|
||||
It needs HSP as the HW synchronization and notification module and
|
||||
IVC module as the message communication protocol.
|
||||
|
||||
This driver manages the IPC interface between host CPU and the
|
||||
firmware running on BPMP.
