Define a compatible string for the Mali Bifrost GPU found in Mediatek's MT8183 SoCs. Signed-off-by: Nicolas Boichat <redacted> --- 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) .../bindings/gpu/arm,mali-bifrost.yaml | 30 ++++++++++++++++++- 1 file changed, 29 insertions(+), 1 deletion(-)
