1 Kernel driver w83l785ts 2 ======================= 3 4 Supported chips: 5 * Winbond W83L785TS-S 6 Prefix: 'w83l785ts' 7 Addresses scanned: I2C 0x2e 8 Datasheet: Publicly available at the Winbond USA website 9 http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/W83L785TS-S.pdf 10 11 Authors: 12 Jean Delvare <jdelvare@suse.de> 13 14 Description 15 ----------- 16 17 The W83L785TS-S is a digital temperature sensor. It senses the 18 temperature of a single external diode. The high limit is 19 theoretically defined as 85 or 100 degrees C through a combination 20 of external resistors, so the user cannot change it. Values seen so 21 far suggest that the two possible limits are actually 95 and 110 22 degrees C. The datasheet is rather poor and obviously inaccurate 23 on several points including this one. 24 25 All temperature values are given in degrees Celsius. Resolution 26 is 1.0 degree. See the datasheet for details. 27 28 The w83l785ts driver will not update its values more frequently than 29 every other second; reading them more often will do no harm, but will 30 return 'old' values. 31 32 Known Issues 33 ------------ 34 35 On some systems (Asus), the BIOS is known to interfere with the driver 36 and cause read errors. Or maybe the W83L785TS-S chip is simply unreliable, 37 we don't really know. The driver will retry a given number of times 38 (5 by default) and then give up, returning the old value (or 0 if 39 there is no old value). It seems to work well enough so that you should 40 not notice anything. Thanks to James Bolt for helping test this feature.
