From 0c2bec96945ccfc4a58a88d73531e392972ba6c5 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Tue, 3 Feb 2009 09:04:20 +0200 Subject: libertas: if_spi: add ability to call board specific setup/teardown methods In certain cases it is required to perform board specific actions before activating libertas G-SPI interface. These actions may include power up of the chip, GPIOs setup, proper pin-strapping and SPI controller config.
