2020-03-31dt-bindings: Add missing 'additionalProperties: false'Rob Herring
Setting 'additionalProperties: false' is frequently omitted, but is important in order to check that there aren't extra undocumented properties in a binding. Ideally, we'd just add this automatically and make this the default, but there's some cases where it doesn't work. For example, if a common schema is referenced, then properties in the common schema aren't part of what's considered for 'additionalProperties'. Also, sometimes there are bus specific properties such as 'spi-max-frequency' that go into bus child nodes, but aren't defined in the child node's schema. So let's stick with the json-schema defined default and add 'additionalProperties: false' where needed. This will be a continual review comment and game of wack-a-mole.

When the APCS clock is registered (platform dependent), it retrieves its parent names from hardcoded values in the driver.

2018-12-21dt-bindings: tegra186-hsp: Add shared mailboxesMikko Perttunen
Shared mailboxes are a mechanism to transport data from one processor in the system to another. They are bidirectional links with both a producer and a consumer. Interrupts are used to let the consumer know when data was written to the mailbox by the producer, and to let the producer know when the consumer has read the data from the mailbox. These interrupts are mapped to one or more "shared interrupts". Typically each processor in the system owns one of these shared interrupts. Add documentation to the device tree bindings about how clients can use mailbox specifiers to request a specific shared mailbox and select which direction they drive. Also document how to specify the shared interrupts in addition to the existing doorbell interrupt.

2018-08-03dt-bindings: mailbox: Add support for secure proxy threadsNishanth Menon
Secure Proxy is another communication scheme in Texas Instrument's devices intended to provide an unique communication path from various processors in the System on Chip(SoC) to a central System Controller. Secure proxy is, in effect, an evolution of current generation Message Manager hardware block found in K2G devices. However the following changes have taken place: Secure Proxy instance exposes "threads" or "proxies" which is primary representation of "a" communication channel. Each thread is preconfigured by System controller configuration based on SoC usage requirements. Secure proxy by itself represents a single "queue" of communication but allows the proxies to be independently operated. Each Secure proxy thread can uniquely have their own error and threshold interrupts allowing for more fine control of IRQ handling. Provide an hardware description of the same for device tree representation.

2018-07-25dt-bindings: remove 'interrupt-parent' from bindingsRob Herring
'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver updates from Arnd Bergmann: "Driver updates for ARM SoCs, including a couple of newly added drivers: - A new driver for the power management controller on TI Keystone - Support for the prerelease "SCPI" firmware protocol that ended up being shipped by Amlogic in their GXBB SoC. - A soc_device can now be matched using a glob from inside the kernel, when another driver wants to know the specific chip it is running on and cannot find out from DT, firmware or hardware. - Renesas SoCs now support identification through the soc_device interface, both in user space and kernel. - Renesas r8a7743 and r8a7745 gain support for their system controller - A new checking module for the ARM "PSCI" (not to be confused with "SCPI" mentioned above) firmware interface. - A new driver for the Tegra GMI memory interface - Support for the Tegra firmware interfaces with their power management controllers As usual, the updates for the reset controller framework are merged here, as they tend to touch multiple SoCs as well, including a new driver for the Oxford (now Broadcom) OX820 chip and the Tegra bpmp interface. The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and Rockchips SoCs see some further updates" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (76 commits) misc: sram: remove useless #ifdef drivers: psci: Allow PSCI node to be disabled drivers: psci: PSCI checker module soc: renesas: Identify SoC and register with the SoC bus firmware: qcom: scm: Return PTR_ERR when devm_clk_get fails firmware: qcom: scm: Remove core, iface and bus clocks dependency dt-bindings: firmware: scm: Add MSM8996 DT bindings memory: da8xx-ddrctl: drop the call to of_flat_dt_get_machine_name() bus: da8xx-mstpri: drop the call to of_flat_dt_get_machine_name() ARM: shmobile: Document DT bindings for Product Register soc: renesas: rcar-sysc: add R8A7745 support reset: Add Tegra BPMP reset driver dt-bindings: firmware: Allow child nodes inside the Tegra BPMP dt-bindings: Add power domains to Tegra BPMP firmware firmware: tegra: Add BPMP support firmware: tegra: Add IVC library dt-bindings: firmware: Add bindings for Tegra BPMP mailbox: tegra-hsp: Use after free in tegra_hsp_remove_doorbells() mailbox: Add Tegra HSP driver firmware: arm_scpi: add support for pre-v1.0 SCPI compatible ...
2016-11-15dt-bindings: mailbox: Add Tegra HSP bindingJoseph Lo
Add DT binding for the Hardware Synchronization Primitives (HSP). The HSP is designed for the processors to share resources and communicate with one another. A set of hardware synchronization primitives for interprocessor communication (IPC) is provided. IPC protocols can use use these hardware synchronization primitives when operating between processors in an AMP configuration.

Message Manager is a hardware block used to communicate with various processor systems within certain Texas Instrument's Keystone generation SoCs. This hardware engine is used to transfer messages from various compute entities(or processors) within the SoC. It is designed to be self contained without needing software initialization for operation.
