	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>

-----------

 | 
			
		||||
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

 | 
			
		||||
up to 5 PWM outputs pwm[1-3,5-6] for controlling fan speeds both manually and
 | 
			
		||||
automatically.
 | 
			
		||||
 | 
			
		||||
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.

The hardware monitoring features of the DME1737 and A8000 are only accessible
 | 
			
		||||
via SMBus, while the SCH311x only provides access via the ISA bus. The driver
 | 
			
		||||
will therefore register itself as an I2C client driver if it detects a DME1737
 | 
			
		||||
or A8000 and as a platform driver if it detects a SCH311x chip.
