2022-06-07arm64: dts: fsd: use local header for pinctrl register valuesKrzysztof Kozlowski2-52/+85
The DTS uses hardware register values directly in pin controller pin configuration. These are not some IDs or other abstraction layer but raw numbers used in the registers. These numbers were previously put in the bindings header to avoid code duplication and to provide some context meaning (name), but they do not fit the purpose of bindings. It is also quite confusing to use constants prefixed with Exynos for other SoC, because there is actually nothing here in common, except the actual value. Store the constants in a header next to DTS and use them instead of bindings.

2022-06-06arm64: dts: fsd: Add cpu cache informationAlim Akhtar1-0/+91
Add CPU caches information so that the same is available to userspace via sysfs. This SoC has 48/32 KB I/D cache for each CPU cores and 4MB of L2 cache.

2022-05-04arm64: dts: fsd: drop useless 'dma-channels/requests' propertiesKrzysztof Kozlowski1-8/+0
The pl330 DMA controller provides number of DMA channels and requests through its registers, so duplicating this information (with a chance of mistakes) in DTS is pointless. Additionally the DTS used always wrong property names which causes DT schema check failures - the bindings documented 'dma-channels' and 'dma-requests' properties without leading hash sign.

2022-04-04arm64: dts: tesla: add a specific compatible to MCT on FSDKrzysztof Kozlowski1-1/+1
One compatible is used for the Multi-Core Timer on Tesla FSD SoC, which is correct but not specific enough. The MCT blocks have different number of interrupts, so add a second specific compatible to Tesla FSD.
