/*
 * The CDS9K currently lives on an SPI bus, and comprises different IP blocks
 * in different applications. For this reason the top level driver does nothing
 * more than expose a regmap on top of its parent bus.
 * As children of this top-level cds9k driver, each copy of each IP block has
 * an entry in the DT for it, and a separate driver is registered for each
 *
 * The sample DTS segment here exposes a CDS9K loaded with at least the
 * following IP blocks:
 *
 * address | IP block    | compatible
 * --------+-------------+---------
 *     0x4 | Fan control | david,cds9k-fan
 *     0x6 | LED control | david,cds9k-led
 *     0x8 | GPIO        | david,cds9k-gpio
 *     0xa | GPIO        | david,cds9k-gpio
