This patch series adds support for exynosautov920, automotive-grade
processor. Although the exynosautov920's TMU hardware differs slightly
from exisiting platform, its read and calibration logic closely follow
our legacy TMU interface. To prevent runtime and build time errors,
it is kept as a single change rather than being split.
This change merges the new exynosautov920-specific register definitions and
timing parameters into the exynos-tmu driver, ensuring consistent behavior
across all Exynos series. All new code paths have been tested on a
exynosautov920 board and verified to correctly read temperatures and
emulate behavior.
Changes in v2:
- Replace the generic property with a vendor-specific one.
- Added an indices property instead of ranges.
- Shortened thermal node name and made them more generic.
- Updated the indices logic accordingly after removing the ranges property.
