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). - First patch applies the DT updates across affected files. - Second patch makes panthor to treat sram-supply as mandatory except mt8196-mali.
