Hi All,
The following patch is one in a series of patches in relation to getting
interrupt-driven Ethernet and USB drivers supported on the Atari Falcon
EtherNAT board. Whoever does have a Falcon with EtherNAT (and CT60,
preferably) running Linux please try out this patch series to help
testing these drivers. For convenience of testing, build the Ethernet
and USB drivers as modules please.
Patches are relative to Geert's v3.3.0 (commit
29c8d8820b6eba2fb6cb2702fd06095a48083595).
Part 1 (this): make room for the EtherNAT interrupts - they appear at
vectors 0xc3 (USB ISP1160) and 0xc4 (SMC91C111)
Part 2: add platform data for the ISP1160 driver, fix the 91C111
interrupt source number (the 91C111 platform data had been added quite
some time ago)
Part 3: make sure the platform devices are added only if the EtherNAT
card is actually present
Part 4: add usb/isp116x.h header to fix compile errors introduced in 2)
Part 5: add Kconfig flag necessary to enable compilation of the ISP1160
driver
Both functions of the EtherNAT are correctly detected with this patch
series. Some mysterious hardware fault in my Falcon does prevent the
card to function properly, however (though at least the 91C111 part with
timer polling did use to work in thee past).
The card interrupts are not being enabled by these patches yet. I need
to discuss with Geert the best way of enabling them as close to the
module loading time as possible.
Cheers,
Michael
