2011-01-14	2f07c8f Browse files » i2c-imx: sync with kernel's driver ... strange behaviour was observed with actual driver : bus lock, probe of absent adresses, wrong data read. This patch sync the driver with linux's one and after a few tests, we don't see anymore strange behaviour (tested on i.MX27).

2010-10-01	b82ee74 Browse files » i2c-imx: wait for STOP before disabling controller ... Makes sure that the STOP condition is transmitted before the I2C controller is disabled. This fixes a problem where writing to an external EEPROM was not working because the EEPROM waits until the STOP before initiating the write internally.

	6d34576 Browse files » i2c-imx: fix clear IFF race condition ... During i2c read the original pattern was: 1. write i2c slave address 2. wait for transmit complete + clear IIF 3. wait for receive acknowledge 4. wait for IIF interrupt Due to the clear of the I2SR register, the IIF flag was cleared, too. So in step 4 the Interrupt wasn't detected. To fix this problem, we move the clean of IIF before the writing of the slave address. So that it looks this way: 0. clear IIF 1. write i2c slave address 2. wait for transmit complete 3. wait for receive acknowledge 4. wait for IIF interrupt Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Marc Kleine-Budde committed on 9 Dec 2009
