* hwmon: do not init sensors on startupHeiko Schocher2011-08-04-27/+2
| | | | | | | | | | | | | | | | | The U-Boot Design Principles[1] clearly say: Initialize devices only when they are needed within U-Boot, i.e. don't initialize the Ethernet interface(s) unless U-Boot performs a download over Ethernet; don't initialize any IDE or USB devices unless U-Boot actually tries to load files from these, etc. (and don't forget to shut down these devices after using them - otherwise nasty things may happen when you try to boot your OS). So, do not initialize and read the sensors on startup. Signed-off-by: Heiko Schocher <hs@denx.de> cc: Wolfgang Denk <wd@denx.de> cc: Holger Brunck <holger.brunck@keymile.com>

| | | | | | | | The checks for CFG_EEPROM_PAGE_WRITE_ENABLE and CFG_EEPROM_PAGE_WRITE_BITS in various temperature sensor drivers are not necessary Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* ppc4xx: Allow DTT_I2C_DEV_CODE configured by CFG_I2C_DTT_ADDRVictor Gallardo2008-09-10-0/+4
| | | | | | | On AMCC Arches board DTT_I2C_DEV_CODE is different then canyonlands and glacier. Signed-off-by: Victor Gallardo <vgallardo@amcc.com>

* DTT: Issue one-shot command on AD7414 (LM75 code) to read tempStefan Roese2008-06-03-0/+13
| | | | | | | | | | | | | | On AD7414 the first value upon bootup is not read correctly. This is most likely because of the 800ms update time of the temp register in normal update mode. To get current values each time we issue the "dtt" command including upon powerup we switch into one-short mode. This patch fixes the problem on AD7414 equipped boards (Sequoia, Canyonlands etc), that temp value printed in the bootup log was incorrect. Signed-off-by: Stefan Roese <sr@denx.de>
* LM75 bug fix for negative temperaturesLarry Johnson2008-02-22-1/+7
| | | | | | | | When the LM75 temperature sensor measures a temperature below 0 C, the current driver does not perform sign extension, so the result returned is 256 C too high. This patch fixes the problem. Signed-off-by: Larry Johnson <lrj@acm.org>
