Hi all,

This series follows the discussion around panthor's SRAM regulator handling
and the DT expectations for mali GPU nodes.

Today, if sram-supply is missing in the DT file, panthor falls back to
a dummy regulator with a warning. This implicit behavior hides missing
DT wiring behind regulator core fallback.

As discussed in [1], the agreed direction is:
- Update DTs to explicitly provide sram-supply, when no separate SRAM
  rail exists, use the same regulator as mali-supply.
- Make panthor to treat sram-supply as mandatory for all compatibles
  except mt8196-mali (as that SoC manages SRAM outside panthor).
Your threading is messed/broken. Start using b4 or just use git
format-patch in a standard way (so one command and then one command for
sending).

Best regards,
Krzysztof
