hwmon: (dme1737) Add support for the SMSC SCH5027
Add support for the SCH5027. The differences to the DME1737 are: - No support for programmable temp offsets - In auto mode, PWM outputs stay on min value if temp goes below low threshold and can't be programmed to fully turn off - Different voltage scaling - No VID input Signed-off-by: Juerg Haefliger <juergh@gmail.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>

Description

-----------

This driver implements support for the hardware monitoring capabilities of the
|
||||
SMSC DME1737 and Asus A8000 (which are the same) and SMSC SCH311x Super-I/O
|
||||
chips. These chips feature monitoring of 3 temp sensors temp[1-3] (2 remote
|
||||
diodes and 1 internal), 7 voltages in[0-6] (6 external and 1 internal) and up
|
||||
to 6 fan speeds fan[1-6]. Additionally, the chips implement up to 5 PWM
|
||||
outputs pwm[1-3,5-6] for controlling fan speeds both manually and

|

|
||||
|
||||
For the DME1737 and A8000, fan[1-2] and pwm[1-2] are always present. Fan[3-6]
|
||||
and pwm[3,5-6] are optional features and their availability depends on the
|
||||
configuration of the chip. The driver will detect which features are present
|
||||
during initialization and create the sysfs attributes accordingly.
