Merge tag 'samsung-dt64-6.8' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into soc/dt
Samsung DTS ARM64 changes for v6.8
Two (and a half) major items are coming with this pull request:
1. Add specific compatibles to all Samsung Exynos and Tesla FSD blocks,
because that's what guidelines expect [1] and is generally
recommended practice. Existing compatibles are left untouched, thus
no driver changes are needed. The work only cleans things up, so any
future contributions will use recommended style: specific and
fallback compatibles.
Since no driver changes are needed in this work and the DTS is
directly affected by bindings change (running tests with `make
dtbs_check`), this pull includes all bindings changes, even though
usual practice is that bindings come via driver subsystem. Keeping
everything here makes review and testing easier. Also will allow us
to avoid conflicts related to new platforms (see below).
2. Add ExynosAutov920 SoC and SADK board (Samsung Automotive Development
Kit) with minimal support so far: serial console, GPIO-based keys and
PWM fan.
3. Add few bindings for upcoming Google GS101 SoC. This pull request
does not include its DTS yet, just few reviewed dependencies. DTS
will be coming soon.
