[PATCH 0/2] tqm85xx: enable PCMCIA bridge on ST85xx baseboards.

[PATCH 0/2] tqm85xx: enable PCMCIA bridge on ST85xx baseboards.

[Dmitry Eremin-Solenikov]

Baseboards for tqm85xx modules (STK85xx) bear TI PCI1520 PCMCIA controllers.
These two patches enables one to fully use this controller in Linux.

[PATCH 1/2] tqm85xx: update PCI interrupt-map attribute

[Dmitry Eremin-Solenikov]

Update PCI IRQ mapping on TQM85xx platforms: include INTC and INTD on PCI-X
slot and add INTA/INTB mapping for PCMCIA bridge.

[PATCH 2/2] tqm85xx: add a quirk for ti1520 PCMCIA bridge

[Dmitry Eremin-Solenikov]

By default ti1520 bridge expects an input clock on CLOCK pin (to control
power chip). However on this boards CLOCK should be generated by PCI1520
itself. Add a quirk that enables internal 16 KHz clock generation on
this pin.
