From b98348bdd08dc4ec11828aa98a78edde15c53cfa Mon Sep 17 00:00:00 2001 From: David Brownell Date: Mon, 4 Feb 2008 22:28:28 -0800 Subject: gpiolib: avr32 at32ap platform support Teach AVR32 to use the "GPIO Library" when exposing its GPIOs, so that signals on external chips (like GPIO expanders) can easily be used. This mostly reorganizes some existing logic, with two minor changes in behavior: - The PSR registers are used instead of the previous "gpio_mask" values, matching AT91 behavior and removing some duplication between that role and that of "pinmux_mask". - NR_IRQs grew to acommodate a bank of external GPIOs. Eventually this number should probably become a board-specific config option. There's a debugfs dump of status for the built-in GPIOs, showing which pins have deglitching, pullups, or open drain drive enabled, as well as the ID string used when requesting each IRQ.
