DT core:
- Add support for generating DT nodes for PCI devices. This is the
groundwork for applying overlays to PCI devices containing
non-discoverable downstream devices.
- DT unittest additions to check reverted changesets, to test for
refcount issues, and to test unresolved symbols. Also, various
clean-ups of the unittest along the way.
- Refactor node and property manipulation functions to better share code
with old API and changeset API
- Refactor changeset print functions to a common implementation
- Move some platform_device specific functions into of_platform.c
Bindings:
- Treewide fixing of typos
- Treewide clean-up of SPDX tags to use 'OR' consistently
- Last chunk of dropping unnecessary quotes. With that, the check
for unnecessary quotes is enabled in yamllint.
- Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi
bindings to DT schema format
- Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450 Inline
Crypto Engine, QCom SM6115 UFS, QCom SDM670 PDC interrupt controller,
Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings
- Fixes for Rockchip DWC PCI binding
- Ensure all properties are evaluated on USB connector schema
- Fix dt-check-compatible script to find of_device_id instances with
compiler annotations

The Ring Accelerator (RA) is a machine which converts read/write accesses
|
|
from/to a constant address into corresponding read/write accesses from/to a
|
|
circular data structure in memory. The RA eliminates the need for each DMA
|
|
controller which needs to access ring elements from having to know the current
|
|
state of the ring (base address, current offset). The DMA controller
|
|
performs a read or write access to a specific address range (which maps to the
|
|
source interface on the RA) and the RA replaces the address for the transaction
|
|
with a new address which corresponds to the head or tail element of the ring
|
|
(head for reads, tail for writes).
|
|
|
|
The Ring Accelerator is a hardware module that is responsible for accelerating
|
|
management of the packet queues. The K3 SoCs can have more than one RA instances
