This file details changes in 2.6 which affect PCMCIA card driver authors:
+* pcmcia_loop_config() and autoconfiguration (as of 2.6.36)
+ If struct pcmcia_device *p_dev->config_flags is set accordingly,
+ pcmcia_loop_config() now sets up certain configuration values
+ automatically, though the driver may still override the settings
+ in the callback function. 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
