Subject: [PATCH 1/3] [OMAPZOOM] Lower i2c speed on bus 1 for LDP.
Date: Wed, 12 Nov 2008 14:21:38 -0600 [thread overview]
Message-ID: <200811121421.38438.dcurran@ti.com> (raw)
Resending patch with more descriptive comment.
Lower i2c bus 1 speed to 400KHz for LDP.
At 2600KHz i2c reads from twl4030 keypad driver are returning
incorrect data. Reason unknown. Lowering bus speed as temporary
fix to get LDP keypad working.
