Some devices are primarily described on another bus (e.g. I2C) but also have an additional SPI connection that serves as a transport for firmware loading. Export of_find_spi_controller_by_node() so drivers can obtain the SPI controller referenced by a DT phandle.

The ALC5575 integrates an audio DSP that typically loads its firmware from an external flash via its own SPI host interface. In certain hardware configurations, the firmware can alternatively be loaded through the SPI client interface. The driver provides basic mute and volume control functions. When the SPI client interface is enabled, firmware loading is handled by the SPI driver.
