CONFIG_GPIO_ADNP: Avionic Design N-bit GPIO expander

General informations

The Linux kernel configuration item CONFIG_GPIO_ADNP:

• prompt: Avionic Design N-bit GPIO expander
• type: tristate
• depends on: CONFIG_OF_GPIO
• defined in drivers/gpio/Kconfig
• found in Linux kernels: 3.7–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12, 6.13-rc+HEAD
• modules built: gpio-adnp

Help text

This option enables support for N GPIOs found on Avionic Design I2C GPIO expanders. The register space will be extended by powers of two, so the controller will need to accommodate for that. For example: if a controller provides 48 pins, 6 registers will be enough to represent all pins, but the driver will assume a register layout for 64 pins (8 registers).
