Merge tag 'samsung-dt64-6.8-2' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into soc/dt
Samsung DTS ARM64 changes for v6.8, part two 1. Tesla FSD: Add Multi Format Codec (MFC) device nodes, for accelerated video de/encoding. 2. Add initial Google Tensor GS101 SoC support. The GS101 SoC can be found on Google Pixel 6 phones. Currently the DTS brings only basic support: core clock controllers, pin controllers, serial, watchdog and ARM core blocks. * tag 'samsung-dt64-6.8-2' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: MAINTAINERS: adjust file entry in GOOGLE TENSOR SoC SUPPORT MAINTAINERS: add entry for Google Tensor SoC arm64: dts: exynos: google: Add initial Oriole/pixel 6 board support arm64: dts: exynos: google: Add initial Google gs101 SoC support dt-bindings: arm: google: Add bindings for Google ARM platforms arm64: dts: fsd: Add MFC related DT enteries Link: https://lore.kernel.org/r/20231220084722.22149-2-krzysztof.kozlowski@linaro.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

ARM platforms using SoCs designed by Google branded "Tensor" used in Pixel
14+
devices.
15+
16+
Currently upstream this is devices using "gs101" SoC which is found in Pixel
17+
6, Pixel 6 Pro and Pixel 6a.
18+
19+
Google have a few different names for the SoC:
20+
- Marketing name ("Tensor")
21+
- Codename ("Whitechapel")
22+
- SoC ID ("gs101")
23+
- Die ID ("S5P9845")
24+
25+
Likewise there are a couple of names for the actual device
26+
- Marketing name ("Pixel 6")
27+
- Codename ("Oriole")
28+
29+
Devicetrees should use the lowercased SoC ID and lowercased board codename,
30+
e.g. gs101 and gs101-oriole.
