hwmon: (lm90) Make code more readable

2011-11-04T11:00:47+00:00

Clean up the code to make it more readable:
* Remove reg_ and new_ prefixes from variable names, they made the
  names longer, causing extra line breaks, while not adding much
  value.
* Introduce struct device dev* = &client->dev in two functions, to
  avoid repeating client->dev everywhere in these functions.

hwmon: (lm90) Fix warnings

2011-11-04T11:00:46+00:00

With some configuration option combinations, we get the following
warnings:

drivers/hwmon/lm90.c: In function 'lm90_detect':
drivers/hwmon/lm90.c:1114: warning: 'chip_id' may be used uninitialized
in this function
drivers/hwmon/lm90.c:1114: warning: 'reg_config1' may be used
uninitialized in this function
drivers/hwmon/lm90.c:1114: warning: 'reg_convrate' may be used
uninitialized in this function
drivers/hwmon/lm90.c:1187: warning: 'reg_emerg2' may be used
uninitialized in this function
drivers/hwmon/lm90.c:1187: warning: 'reg_status2' may be used
uninitialized in this function

We can solve these easily by reading the register values first and
checking for errors later. These errors should be very rare, even in
the case of failed detection, so this change has no impact on
performance. And this makes checkpatch.pl happier.

hwmon: (lm90) Refactor reading of config2 register

2011-07-29T03:16:36+00:00

Several vendors implement a second configuration register, which we
check during device detection. Refactor the code to avoid duplication.

hwmon: (lm90) Make SA56004 detection more robust

2011-07-29T03:16:36+00:00

With a device ID register value of 0, the SA56004 detection is rather
weak. Check several other register too to confirm the detection, as we
do for other supported devices.

hwmon: (lm90) Simplify handling of extended local temp register

2011-07-29T03:16:35+00:00

The optional extended local temperature register can never have
address 0, as this address is already used by another register. Thus
we can get rid of flag LM90_HAVE_LOCAL_EXT and simply rely on
reg_local_ext being non-zero to determine if a given chip has this
extension or not. This makes the code more simple.

hwmon: (lm90) Add support for ADT7461A and NCT1008

2011-04-29T14:33:35+00:00

This patch adds support for ADT7461A and NCT1008 to the lm90 driver.
Both chips have identical functionality and report the same manufacturing ID
and device ID values.

hwmon: (lm90) Add support for the W83L771W/G

I was wondering if that chip ever existed publicly... Apparently yes,
so add support for it.
