(no changes since v12)
Changes in v12:
- binding: Fix min/maxItems logic (Rob Herring)
Changes in v11:
- binding: power-domain-names not power-domainS-names
Changes in v10:
- Fix the binding to make sure sram-supply property can be provided.
Changes in v6:
- Rebased, actually tested with recent mesa driver.
Changes in v5:
- Rename "2d" power domain to "core2"
Changes in v4:
- Add power-domain-names description
(kept Alyssa's reviewed-by as the change is minor)
