 This driver implements support for the hardware monitoring capabilities of the
-SMSC DME1737 and Asus A8000 (which are the same) Super-I/O chips. This chip
-features 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 6 fan speeds
-fan[1-6]. Additionally, the chip implements 5 PWM outputs pwm[1-3,5-6] for
-controlling fan speeds both manually and automatically.

+sysfs attribute writes interpretation
+-------------------------------------
 
-eeprom		Raw EEPROM data in binary form.
-		RO
+hwmon sysfs attributes always contain numbers, so the first thing to do is to
+convert the input to a number, there are 2 ways todo this depending whether
+the number can be negative or not:
+unsigned long u = simple_strtoul(buf, NULL, 10);
+long s = simple_strtol(buf, NULL, 10);
 
-pec		Enable or disable PEC (SMBus only)
-		0: disable
-		1: enable
-		RW
+With buf being the buffer with the user input being passed by the kernel.
+Notice that we do not use the second argument of strto[u]l, and thus cannot
+tell when 0 is returned, if this was really 0 or is caused by invalid input.
+This is done deliberately as checking this everywhere would add a lot of
+code to the kernel.
+
+Notice that it is important to always store the converted value in an
+unsigned long or long, so that no wrap around can happen before any further
+checking.
+
+After the input string is converted to an (unsigned) long, the value should be
+checked if its acceptable. Be careful with further conversions on the value
+before checking it for validity, as these conversions could still cause a wrap
+around before the check. For example do not multiply the result, and only
+add/subtract if it has been divided before the add/subtract.
+
+What to do if a value is found to be invalid, depends on the type of the
+sysfs attribute that is being set. If it is a continuous setting like a
+tempX_max or inX_max attribute, then the value should be clamped to its
+limits using SENSORS_LIMIT(value, min_limit, max_limit). If it is not
+continuous like for example a tempX_type, then when an invalid value is
+written, -EINVAL should be returned.
+
+Example1, temp1_max, register is a signed 8 bit value (-128 - 127 degrees):
+
+	long v = simple_strtol(buf, NULL, 10) / 1000;
+	v = SENSORS_LIMIT(v, -128, 127);
+	/* write v to register */
+
+Example2, fan divider setting, valid values 2, 4 and 8:
+
+	unsigned long v = simple_strtoul(buf, NULL, 10);
+
+	switch (v) {
+	case 2: v = 1; break;
+	case 4: v = 2; break;
+	case 8: v = 3; break;
+	default:

+The sysfs interface to the gloabal enable is via the sysfs beep_enable file.
+This file is used for both legacy and new code.
 
-*** NOTE: It is the responsibility of user-space code to handle the fact
-that the beep enable and alarm bits are in different positions when using that
-feature of the chip.
+The sysfs interface to the beep bitmask has migrated from the original legacy
+method of a single sysfs beep_mask file to a newer method using multiple
+*_beep files as described in .../Documentation/hwmon/sysfs-interface.
 
-When an alarm goes off, you can be warned by a beeping signal through your
-computer speaker. It is possible to enable all beeping globally, or only
-the beeping for some alarms.
+A similar change has occured for the bitmap corresponding to the alarms. The
+original legacy method used a single sysfs alarms file containing a bitmap
+of triggered alarms. The newer method uses multiple sysfs *_alarm files
+(again following the pattern described in sysfs-interface).
 
-The driver only reads the chip values each 3 seconds; reading them more
-often will do no harm, but will return 'old' values.
+Since both methods read and write the underlying hardware, they can be used
+interchangeably and changes in one will automatically be reflected by
+the other. If you use the legacy bitmask method, your user-space code is
+responsible for handling the fact that the alarms and beep_mask bitmaps
+are not the same (see the table below).
+
+NOTE: All new code should be written to use the newer sysfs-interface
+specification as that avoids bitmap problems and is the preferred interface
+going forward.
+
+The driver reads the hardware chip values at most once every three seconds.
+User mode code requesting values more often will receive cached values.

+ * the chip registers if a DME1737 (or A8000) is found and the ISA bus if a
+ * SCH311x chip is found. Both types of chips have very similar hardware
