[PATCH 5/6] crypto: ux500/cryp - Enable DT probing of the driver

[Lee Jones]

By providing an OF match table with a suitable compatible string, we
can ensure the ux500-crypt driver is probed by supplying an associated
DT node in a given platform's Device Tree.

Herbert, can I have your ACK on patch 5 & 6 in this series to take it
through the ARM SoC tree?

Yours,

Right, there are no bindings, so they don't need a document.

Surely the requirement that the node must have <reg>,
<irqs> and <regulator> for the driver to even probe is a
binding?

The fact that the drivers/of/* core on Linux will auto-populate
platform devices with those properties is a pure Linux
pecularity, and the bindings are there for OS independence.

Whether we need to document it for such standard things
is another thing, hopefully Rob or someone can answer that?

Linus Walleij

W00t! No binding document?

OK I guess it's just reg, irq ... but still it's compulsory,
right?

[PATCH 6/6] crypto: ux500/hash - Enable DT probing of the driver

[Lee Jones]

By providing an OF match table with a suitable compatible string, we
can ensure the ux500-hasht driver is probed by supplying an associated
DT node in a given platform's Device Tree.
