Subject: [PATCH] hwmon: (nct7904) Add extra sysfs support for fan, voltage and tempearture. Fix the incorrect value of tcpu_mask in nct7904_data struct.
From: "amy.shih" <amy.shih@...antech.com.tw>
This patch do 3 jobs as described in below:
1. NCT-7904D also supports reading of channel limitation registers
and SMI status registers for fan, voltage and tempearture monitoring,
add below sysfs nodes:
-fan[1-*]_min
-fan[1-*]_alarm
-in[0-*]_min
-in[0-*]_max
-in[0-*]_alarm
-temp[1-*]_max
-temp[1-*]_max_hyst
-temp[1-*]_emergency
-temp[1-*]_emergency_hyst
-temp[1-*]_alarm
2. Add the temp[1-*]_type sysfs to show type of tempearture sensor is
thermal diode, thermistor, AMD SB-TSI or Intel PECI.
3. Detect the multi-function of voltage, thermal diode and thermistor
from register VT_ADC_MD_REG to set value of tcpu_mask in nct7904_data
struct, set temp[1-5]_input the input values TEMP_CH1~4 and LTD of
temperature. Set temp[6~13]_input the input values of DTS temperature
that correspond to sensors TCPU1~8.
