Summary
SPI devices can be defined using a “spidev” name, as demonstrated by the Linux kernel documentation.
1
This can be used to measure the amount of ambient light by using a voltage divider in a circuit.
2
The spidev framework enables users to control an SPI peripheral from Linux user space, and the spidev_test tool is available within the Linux kernel to perform tests via the spidev interface.

Summary
It used to be supported to define an SPI device using the “spidev” name. For example, as .modalias = “spidev” or compatible = “spidev”. But this is no longer supported by the Linux kernel and instead a real SPI device name as listed in one of the tables must be used.

Summary
The spidev framework enables users to easily control an SPI peripheral from Linux user space. This can be done through the board device tree, SPI hardware tests, and device tree configuration. The spidev_test tool is available within the Linux kernel and can be used to perform tests via the spidev interface.
