Jean Delvare 67f921d164 hwmon: (lm70) Add a name attribute
Add a name attribute to the lm70 devices. This is required for
libsensors to recognize them.

Also drop the "+" before the temperature value, even though it did
not cause problems to libsensors, other hardware monitoring drivers
don't print it, so it's more consistent that way.

David Brownell c06e677aed SPI: add 3wire mode flag
Add a new spi->mode bit: SPI_3WIRE, for chips where the SI and SO signals
are shared (and which are thus only half duplex).  Update the LM70 driver
to require support for that hardware mode from the controller.

Kaiwan N Billimoria e1a8e913f9 [PATCH] lm70: New hardware monitoring driver
This driver implements support for the National Semiconductor LM70
temperature sensor.

The LM70 temperature sensor chip supports a single temperature sensor.
It communicates with a host processor (or microcontroller) via an
SPI/Microwire Bus interface.

Communication with the LM70 is simple: when the temperature is to be sensed,
the driver accesses the LM70 using SPI communication: 16 SCLK cycles
comprise the MOSI/MISO loop. At the end of the transfer, the 11-bit 2's
complement digital temperature (sent via the SIO line), is available in the
driver for interpretation. This driver makes use of the kernel's in-core
SPI support.
