2 spi_lm70llp : LM70-LLP parport-to-SPI adapter
5 Supported board/chip:
7 * National Semiconductor LM70 LLP evaluation board
15 -----------
17 temperature sensor evaluation board to the kernel's SPI core subsystem.
21 In effect, this driver turns the parallel port interface on the eval board
27 --------------------
28 The schematic for this particular board (the LM70EVAL-LLP) is

33 The hardware interfacing on the LM70 LLP eval board is as follows:
39 D0 2 - -
40 D1 3 --> V+ 5
41 D2 4 --> V+ 5
42 D3 5 --> V+ 5
43 D4 6 --> V+ 5
44 D5 7 --> nCS 8
45 D6 8 --> SCLK 3
46 D7 9 --> SI/O 5
47 GND 25 - GND 7
48 Select 13 <-- SI/O 1
51 Note that since the LM70 uses a "3-wire" variant of SPI, the SI/SO pin
54 pin low. This can't be shared with true SPI devices, but other 3-wire

82 - David Brownell for mentoring the SPI-side driver development.
83 - Dr.Craig Hollabaugh for the (early) "manual" bitbanging driver version.
84 - Nadir Billimoria for help interpreting the circuit schematic.
