 This file details changes in 2.6 which affect PCMCIA card driver authors:
 
+* no cs_error / CS_CHECK / CONFIG_PCMCIA_DEBUG (as of 2.6.33)
+   Instead of the cs_error() callback or the CS_CHECK() macro, please use
+   Linux-style checking of return values, and -- if necessary -- debug
+   messages using "dev_dbg()" or "pr_debug()".
+
+* New CIS tuple access (as of 2.6.33)
+   Instead of pcmcia_get_{first,next}_tuple(), pcmcia_get_tuple_data() and
+   pcmcia_parse_tuple(), a driver shall use "pcmcia_get_tuple()" if it is
+   only interested in one (raw) tuple, or "pcmcia_loop_tuple()" if it is
+   interested in all tuples of one type. To decode the MAC from CISTPL_FUNCE,
+   a new helper "pcmcia_get_mac_from_cis()" was added.
+
+* New configuration loop helper (as of 2.6.28)
+   By calling pcmcia_loop_config(), a driver can iterate over all available
+   configuration options. During a driver's probe() phase, one doesn't need
+   to use pcmcia_get_{first,next}_tuple, pcmcia_get_tuple_data and
+   pcmcia_parse_tuple directly in most if not all cases.
+
 * New release helper (as of 2.6.17)
    Instead of calling pcmcia_release_{configuration,io,irq,win}, all that's
    necessary now is calling pcmcia_disable_device. As there is no valid

-* Convert internal I/O port addresses to unsigned long (as of 2.6.11)
-   ioaddr_t should be replaced by kio_addr_t in PCMCIA card drivers.
