arm64: dts: fsd: fix drive strength values as per FSD HW UM

2022-10-18T13:24:00Z

Drive strength values used for HSI2C, SPI and UART are not reflecting the default values recommended by FSD HW UM.

arm64: dts: fsd: fix drive strength macros as per FSD HW UM

2022-10-18T13:23:59Z

Drive strength macros defined for FSD platform is not reflecting actual names and values as per HW UM. FSD SoC pinctrl has following four levels of drive-strength and their corresponding values: Level-1 <-> 0 Level-2 <-> 1 Level-4 <-> 2 Level-6 <-> 3 The commit 684dac402f21 ("arm64: dts: fsd: Add initial pinctrl support") used drive strength macros defined for Exynos4 SoC family. For some IPs the macros values of Exynos4 matched and worked well, but Exynos4 SoC family drive-strength (names and values) is not exactly matching with FSD SoC. Fix the drive strength macros to reflect actual names and values given in FSD HW UM.

arm64: dts: fsd: use local header for pinctrl register values

2022-06-07T06:56:17Z

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.

arm64: dts: fsd: drop useless 'dma-channels/requests' properties

2022-05-04T08:22:19Z

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.

arm64: dts: tesla: add a specific compatible to MCT on FSD

2022-04-04T16:53:08Z

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.
