From cff37c9e82e022068840b3d33167e64c6a0ecc06 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Thu, 27 May 2010 19:58:57 +0200 Subject: hwmon: (tmp102) Various fixes Fixes from my driver review: http://lists.lm-sensors.org/pipermail/lm-sensors/2010-March/028051.html Only the small changes are in there, more important changes will come later separately as time permits. * Drop the remnants of the now gone detect function * The TMP102 has no known compatible chip * Include the right header files * Clarify why byte swapping of register values is needed * Strip resolution info bit from temperature register value * Set cache lifetime to 1/3 second * Don't arbitrarily reject limit values; clamp as needed * Make limit writing unconditional * Don't check for transaction types the driver doesn't use * Properly check for error when setting configuration * Report error on failed probe * Make the driver load automatically where needed * Various other minor fixes Signed-off-by: Jean Delvare Cc: Steven King --- Documentation/hwmon/tmp102 | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) (limited to 'Documentation/hwmon') diff --git a/Documentation/hwmon/tmp102 b/Documentation/hwmon/tmp102 index 239dded8539f..8454a7763122 100644 --- a/Documentation/hwmon/tmp102 +++ b/Documentation/hwmon/tmp102 @@ -4,7 +4,7 @@ Kernel driver tmp102 Supported chips: * Texas Instruments TMP102 Prefix: 'tmp102' - Addresses scanned: I2C 0x48 0x49 0x4a 0x4b + Addresses scanned: none Datasheet: http://focus.ti.com/docs/prod/folders/print/tmp102.html Author: @@ -15,13 +15,12 @@ Description The Texas Instruments TMP102 implements one temperature sensor. Limits can be set through the Overtemperature Shutdown register and Hysteresis register. The -sensor is accurate to 0.5 degrees over the range of -25 to +85 C, and to 1.0 -degrees from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The +sensor is accurate to 0.5 degree over the range of -25 to +85 C, and to 1.0 +degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The operating temperature has a minimum of -55 C and a maximum of +150 C. The TMP102 has a programmable update rate that can select between 8, 4, 1, and 0.5 Hz. (Currently the driver only supports the default of 4 Hz). The driver provides the common sysfs-interface for temperatures (see -/Documentation/hwmon/sysfs-interface under Temperatures). - +Documentation/hwmon/sysfs-interface under Temperatures). -- cgit v1.2.1
