It is a bit confusing... how did that driver got merged recently without bindings? Why bindings are separate? The bindings always come together in one patchset with the driver implementing them. Bindings are though a separate patch, yet still followed by the driver which uses them. I do not see any compatibles in that driver, which suggests there is no other binding using it.

It is a bit confusing... how did that driver got merged recently without bindings? Why bindings are separate? The bindings always come together in one patchset with the driver implementing them. Bindings are though a separate patch, yet still followed by the driver which uses them. I do not see any compatibles in that driver, which suggests there is no other binding using it. If that's correct, then you need to change the driver.
