* hwmon: do not init sensors on startupHeiko Schocher2011-08-04-18/+1
| | | | | | | | | | | | | | | | | 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>
* ds1621: Fix negative temperature readingsJeff Dischler2010-10-06-1/+1
| | | | | | | | | Fix bug where signed data was processed as unsigned. The bug previously resulted in negative temperature readings wrapping around, eg -10 became 245. Signed-off-by: Jeff Dischler <jdischler@xes-inc.com> Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

* ds1621: Poll for register write completionPeter Tyser2010-10-06-5/+21
| | | | | | | | | Poll the ds1621 NV Memory Busy bit instead of waiting a static amount of time for register writes. Also add config retister bit defines. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

* Remove CFG_EEPROM_PAGE* dependencies for temperature sensorsPeter Tyser2008-10-14-5/+0
| | | | | | | | 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>
