From a02a2956809d88b42b9a1f8003d60a343353b5ea Mon Sep 17 00:00:00 2001 From: Grazvydas Ignotas Date: Fri, 16 Apr 2010 13:22:12 +0300 Subject: wl1251: add support for dedicated IRQ line wl1251 has WLAN_IRQ pin for generating interrupts to host processor, which is mandatory in SPI mode and optional in SDIO mode (which can use SDIO interrupts instead). However TI recommends using deditated IRQ line for SDIO too. Add support for using dedicated interrupt line with SDIO, but also leave ability to switch to SDIO interrupts in case it's needed.
