arm64: tegra: Changes for v6.20-rc1
This update improves Device Tree support for 64-bit Tegra platforms,
specifically focusing on the Smaug board and the Tegra264 SoC. It
enables full USB-C functionality on Smaug by adding role-switching
support and enabling DisplayPort altmode. For Tegra264, it introduces
nodes for Command Queue Virtualization (CMDQV) in the SMMU, adds the
Data Backbone (DBB) clock for the memory controller, and corrects CPU
compatible strings to match the Neoverse V3AE core. Additionally, it
performs a cleanup by removing redundant status = "okay" properties
across Tegra186, Tegra194, Tegra234, and Tegra264 files.

In the RZ/N1 SoC, the GPIO interrupts are multiplexed using the GPIO
Interrupt Multiplexer.
Add the multiplexer node and connect GPIO interrupt lines to the
multiplexer.
The interrupt-map available in the multiplexer node has to be updated in
dts files depending on the GPIO usage. Indeed, the usage of an interrupt
for a GPIO is board dependent.
Up to 8 GPIOs can be used as an interrupt line (one per multiplexer
output interrupt).
On the Renesas RZ/N1 SoC, GPIOs can generate interruptions. Those
interruption lines are multiplexed by the GPIO Interrupt Multiplexer in
order to map 32 * 3 GPIO interrupt lines to 8 GIC interrupt lines.
The GPIO interrupt multiplexer IP does nothing but select 8 GPIO
IRQ lines out of the 96 available to wire them to the GIC input lines.

Merge patch series "arm64: dts: apple: Add integrated USB Type-C ports"
Janne Grunau <j@jannau.net> says:
Now that all dependencies for USB 2.0 and 3.x support are either merged
(tipd changes in v6.18, dwc3-apple in v6.19-rc1) or in linux-next (Apple
Type-C PHY) prepare device tree changes to expose the ports.
Each port on Apple silicon devices is driven by a separate collection of
hardware blocks. For USB 2.0 and 3.x the collection consists of:
- Apple Type-C PHY, combo PHY for USB 2.0, USB 3.x, USB4/Thunderbolt and
DisplayPort
- Synopsys Designware dwc3 USB controller
- two DART iommu instances for dwc3
- CD321x USB PD controller (similar to Ti's TPS6598x series)
The CD321x nodes are already present so this series add the remaining
devices nodes, typec connector nodes and connections between all
components.
The devices expose except for a few exceptions noted below all ports. M1
and M2 have two ports, M1 and M2 Pro and Max have four ports and
M1 and M2 Ultra have eight ports.
The Pro and Max based Macbook Pros use only three ports. The fourth port
is used as DisplayPort PHY to drive a HDMI output via an integrated
DP to HDMI converter.
The Ultra based Mac studio devices only use six ports. The third and
fourth port on the second die is completely fused off.
The changes for t600x and t602x are in a single commit since the devices
share .dtsi files across SoC generations due to their similarity.
Depends on commit c1538b87caef ("dt-bindings: phy: Add Apple Type-C
PHY") in linux-phy's [1] next branch for `make dtbs_check` to pass.
checkpatch warns about the undocumented DT compatible strings
"apple,t8112-atcphy", "apple,t6000-atcphy" and "apple,t6020-atcphy" but
not about "apple,t8103-atcphy". I don't under why it doesn't warn about
the last. "apple,t8103-atcphy" is only found in the added devicetree

Add properties declared in the new DT binding nxp,lpc3220-dmamux.yaml
and corresponding phandles.
[vzapolskiy]:
1. rebased the change,
2. dmamux unit address shall be 0x78 instead of 0x7c,
3. removed unsupported 'dmas' properties from sd, ssp0, ssp1 and HS UARTs,
4. more non-functional updates by reordering properies,
5. minor updates to the commit message.

ARM: dts: lpc32xx: Use syscon for system control block
The clock controller is a part of NXP LPC32xx system control block (SCB),
and SCB provides a number of controllers apart of the clock controller.
[vzapolskiy]:
1. kept a simple comment,
2. renamed SoC specific compatible to 'nxp,lpc3220-scb' due to the SoC UM,
3. changed size in 'ranges', since it should cover more SCB functions,
4. updated the commit message.

ARM: dts: lpc32xx: Update spi clock properties
PL022 binding require two clocks to be defined but NXP LPC32xx platform
doesn't comply with the bindings and define only one clock i.e apb_pclk.
Update SPI clocks and clocks-names property by adding appropriate clock
reference to make it compliant with the bindings.
Noteworthy, strictly speaking the change tackles DT ABI by changing
the order in the list of clock-names property values, however this level
of impact is considered as acceptable.

ARM: dts: aspeed: ibm: Use non-deprecated AT25 properties
The at25,* properties have been deprecated since 2012. These platforms
weren't upstream until 2020 and 2023, so it should be safe to switch
over to the "new" properties and just drop the deprecated ones.

ARM: dts: aspeed: bletchley: Remove try-power-role from connectors
Remove the "try-power-role = sink" property from all USB-C connectors.
The try mechanism is unnecessary and wastes time during connection.
Since power-role = "dual" is already configured, standard USB PD
negotiation is sufficient and more efficient.

ARM: dts: aspeed: Add Facebook Anacapa platform
The Meta Anacapa BMC is the DC-SCM (Data Center Secure Control
Module) controller for the Meta OCP Open Rack Wide (ORW) compute tray.
This platform is a key component of the AMD Helios AI rack reference
design system, designed for next-generation AI workloads.
The BMC utilizes the Aspeed AST2600 SoC to manage the compute tray, which
contains up to 4 AMD Instinct MI450 Series GPUs (connected via a Broadcom
OCP NIC) and host CPUs. Its primary role is to provide essential system
control, power sequencing, and telemetry reporting for the compute complex
via the OpenBMC software stack.
