* 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>
* LM73 bug fix for negative temperatures and cleanupLarry Johnson2008-04-13-30/+30
| | | | | | | | | When the LM73 temperature sensor measures a temperature below 0 C, the current driver does not perform sign extension, so the result returned is 512 C too high. This patch fixes the problem, and does general cleanup of the code. Signed-off-by: Larry Johnson <lrj@acm.org>
