Subject: spi: cadence-quadspi: Provide a capability structure
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a9be454927de3b6df8ca4cbd88e019e52b73d4b4;p=linux.git

spi: cadence-quadspi: Provide a capability structure

This controller has DTR support, so advertize it with a capability now
that the spi-controller structure contains this new field. This will
later be used by the core to discriminate whether an operation is
supported or not, in a more generic way than having different helpers.
