Subject: [PATCH v2 12/12] spi: spidev: Add an entry for the gocontroll
 moduline module slot

From: Maud Spierings <maudspierings@...ontroll.com>

The main point of the Moduline series of embedded controllers is its
ecosystem of IO modules, these are currently operated through the spidev
interface. Ideally there will be a full dedicated driver in the future.

Add the gocontroll moduline-module-slot device to enable the required
spidev interface.
