From 0e450c7ce7d170a78adaeaa9a430e4184f191c15 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Thu, 27 Jan 2022 10:17:59 +0100 Subject: [PATCH] spi: mxic: 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.
