Subject: [PATCH] i2c-s3c2410: Enable i2c clock only on xfer
Date: Sat, 17 Apr 2010 23:42:32 +0300 [thread overview]
Message-ID: <201004172342.43440.anarsoul@gmail.com> (raw)
I don't see any reason to keep i2c clock enabled all the time when i2c bus
driver is loaded, and even more: it prevents me to disable uda1380 codec power
- uda1380 doesn't respond on i2c xfers if its power was disabled during i2c
clock is enabled.
WinMobile enables i2c clock only on xfer (same for i2s clock)
Regards
Vasily
