The following autoconfiguration options + are provided at the moment: + CONF_AUTO_CHECK_VCC : check for matching Vcc + CONF_AUTO_SET_VPP : set Vpp + CONF_AUTO_AUDIO : auto-enable audio line, if required + CONF_AUTO_SET_IO : set ioport resources (->resource[0,1]) + CONF_AUTO_SET_IOMEM : set first iomem resource (->resource[2]) + +* pcmcia_request_configuration -> pcmcia_enable_device (as of 2.6.36) + pcmcia_request_configuration() got renamed to pcmcia_enable_device(), + as it mirrors pcmcia_disable_device(). Configuration settings are now + stored in struct pcmcia_device, e.g. in the fields config_flags, + config_index, config_base, vpp. + +* pcmcia_request_window changes (as of 2.6.36) + Instead of win_req_t, drivers are now requested to fill out + struct pcmcia_device *p_dev->resource[2,3,4,5] for up to four ioport + ranges. After a call to pcmcia_request_window(), the regions found there + are reserved and may be used immediately -- until pcmcia_release_window() + is called. + * pcmcia_request_io changes (as of 2.6.36) Instead of io_req_t, drivers are now requested to fill out struct pcmcia_device *p_dev->resource[0,1] for up to two ioport |
