| * | twl4030-gpio: cleanup debounce | David Brownell | 2009-01-06 | 1 | -31/+23 |
| | | | | | | | | | | | | | | | | | | Provide a static debounce configuration mechanism for twl4030 GPIOs, replacing the previous dynamic one. The single user of that mechanism was for MMC card detect debouncing. Boards can provide a bitmask saying which GPIOs to debounce (30 msec). It's always enabled for pins with the MMC card-detect/VMMCx link active, so most boards won't need to set the debounce mask. This is a net code shrink, including runtime footprint.

| * | mfd: twl4030-gpio driver | David Brownell | 2008-10-22 | 1 | -0/+521 |
| This adds basic support for the GPIOs in the twl4030 power management chip. That includes two open drain LED drivers, and the use of GPIO-0 (and GPIO-1) as MMC/SD card detect switches which can control whether the VMMC1 (and VMMC2) regulators are active. This version of the code has a debounce call that will probably be replaced before long, when a more generic interface exists.
