dt-bindings: tegra: pmc: Add Tegra264 compatible

2025-07-11T14:48:06Z

The PMC found on Tegra264 is similar to the version in earlier chips but some of the register offsets and bitfields differ, so add a specific compatible string for this new generation.

dt-bindings: tegra: pmc: Update scratch as an optional aperture

2024-02-16T11:18:14Z

Scratch address space register is used to store reboot reason. For some Tegra234 systems, the scratch space is not available to store the reboot reason. This is because scratch region on these systems is not accessible by the kernel as restricted by the Hypervisor. Such systems would delist scratch aperture from PMC DT node. Accordingly, this change makes "scratch" as an optional aperture for Tegra234 in PMC dt-binding document.

dt-bindings: arm: tegra: pmc: Restructure pad configuration node schema

2023-10-10T15:39:33Z

The pad configuration node schema in its current form can accidentally match other properties as well. Restructure the schema to better match how the device trees are using these. Reviewed-by: Rob Herring Signed-off-by: Thierry Reding

dt-bindings: arm: tegra: pmc: Increase maximum number of clocks per powergate

2023-10-10T15:39:33Z

Some powergate definitions need more than 8 clocks, so bump the number up to 10, which is the current maximum in any known device tree file. Acked-by: Rob Herring Signed-off-by: Thierry Reding

dt-bindings: arm: tegra: pmc: Move additionalProperties

2023-10-10T15:39:33Z

For indented subschemas it can be difficult to understand which block an additionalProperties property belongs to. Moving it closer to the beginning of a block is a good way to clarify this. Reviewed-by: Rob Herring Signed-off-by: Thierry Reding
