dme1737 datasheet

Hi,

Given the NDA nature it's tricky trying to support the watchdog and
serial port for LinuxBIOS.  I think I can fly blind using parts of
publicly available datasheets, but it would save me time if I knew the
Logical Device #'s of the various superio modules, ie index 7 values
needed to address parport, serial 1/2, fdc, etc. config registers.

Any chance someone can hint at what these might be, or a publicly
available datasheet that's closest:

http://www.smsc.com/main/datasheet.html

Ok so they all have serial port as Logical Device 4, so I've summarized
what the watchdog uses below.

ISA bus types - Config index/data registers at 0x3F0 or 0x370

watchdog uses configuration space of logical device

FDC37b727 Logical Device 8 - Aux I/O 0xF1 - 0xF4 watchdog *
FDC37b78x Logical Device 8 - Aux I/O 0xF1 - 0xF4 watchdog *
FDC37c665GT very different - no logical devices
FDC37c669 very different - no logical devices
FDC37c672 Logical Device 8 - Aux I/O 0xF1 - 0xF4 watchdog * no
WDT_TIME_OUT register
FDC37c78 FDC only
FDC37c93x Logical Device 8 - Aux I/O 0xF2 - 0xF4 watchdog *
FDC37M707 Logical Device 8 - Aux I/O 0xF1 - 0xF4 watchdog *
FDC37m817 Logical Device 8 - Aux I/O 0xF1 - 0xF4 watchdog *
FDC37n769 very different - no logical devices

* can be configured to allow access to some watchdog registers while in
run mode

LPC bus types - index/address registers 0x2e/0x2f or 0x4e/0x4f

watchdog uses offset from decoded address set by logical device Primary
Base Address 

LPC47b272 Logical Device A - Runtime reg offset 0x52 - 0x55 watchdog
LPC47m10x no WDT
LPC47m112 no WDT
LPC47m172 no WDT
LPC47S45x Logical Device A - Runtime reg offset 0x52 - 0x55 watchdog

I'm leaning towards DME1737 being the same as these LPC parts.
