CONFIG_SPI_BITBANG: Utilities for Bitbanging SPI host controllers

General informations

The Linux kernel configuration item CONFIG_SPI_BITBANG has multiple definitions:

Utilities for Bitbanging SPI host controllers found in drivers/spi/Kconfig

The configuration item CONFIG_SPI_BITBANG:

• prompt: Utilities for Bitbanging SPI host controllers
• type: tristate
• depends on: (none)
• defined in drivers/spi/Kconfig
• found in Linux kernels: 6.10–6.12, 6.13-rc+HEAD
• modules built: spi-bitbang, spi_bitbang

Help text

With a few GPIO pins, your system can bitbang the SPI protocol. Select this to get SPI support through I/O pins (GPIO, parallel port, etc). Or, some systems' SPI host controller drivers use this code to manage the per-word or per-transfer accesses to the hardware shift registers.

This is library code, and is automatically selected by drivers that need it. You only need to select this explicitly to support driver modules that aren't part of this kernel tree.
