47 this symbol, but new drivers should use the generic gpio-regmap
57 non-sleeping contexts. They can make bitbanged serial protocols
118 Enables support for the idio-16 library functions. The idio-16 library
120 ACCES IDIO-16 family such as the 104-IDIO-16 and the PCI-IDIO-16.
122 If built as a module its name will be gpio-idio-16.
128 tristate "GPIO driver for 74xx-ICs with MMIO access"
132 Say yes here to support GPIO functionality for 74xx-compatible ICs
133 with MMIO access. Compatible models include:
149 If driver is built as a module it will be called gpio-altera.

8 * directly to pads on the SoC, others come from an 8-bit pcf857x IO
10 * one set for the pcf857x, and one set for the pio controller.
