* GPIO: MIPS: lantiq: convert gpio-mm-lantiq to OF and of_mm_gpioJohn Crispin2012-05-211-57/+89
| | | | | | | | | | | | | | | Implements OF support and convert to of_mm_gpio. By attaching hardware latches to the External Bus Unit (EBU) on Lantiq SoC, it is possible to create output only gpios. This driver configures a special memory address, which when written to, outputs 16 bit to the latches.

* GPIO: MIPS: lantiq: move gpio-stp and gpio-ebu to the subsystem folderJohn Crispin2012-05-211-0/+126
Move the 2 drivers from arch/mips/lantiq/xway/ to the subsystem and make them buildable. The following 2 patches will convert the drivers to OF.
