From 440eed43e2a95bb842488755683716814da10f2b Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Fri, 30 Jul 2010 09:51:52 +0200 Subject: pcmcia: introduce autoconfiguration feature Introduce an autoconfiguration feature to set certain values in pcmcia_loop_config(), instead of copying the same code over and over in each PCMCIA driver. At first, introduce the following options: CONF_AUTO_CHECK_VCC check or matching Vcc entry CONF_AUTO_SET_VPP set Vpp CONF_AUTO_AUDIO enable the speaker line CC: netdev@vger.kernel.org CC: linux-wireless@vger.kernel.org CC: linux-ide@vger.kernel.org CC: linux-usb@vger.kernel.org CC: laforge@gnumonks.org CC: linux-mtd@lists.infradead.org CC: alsa-devel@alsa-project.org CC: linux-serial@vger.kernel.org CC: Jiri Kosina CC: linux-scsi@vger.kernel.org Acked-by: Gustavo F.
