* Allow data-only i2c transfersRosen Kolev2011-10-071-24/+28
| | | | | | | | | | Modified the i2c_imx driver to support data-only transfers, without command byte. This allows to construct more complex i2c transfers and support non genuine devices like Atmel ATxx secure memory, where the master reads data after a write command.

* introduce io.hSascha Hauer2011-09-222-2/+2

* i2c-imx: sync with kernel's driverEric Bénard2011-01-141-27/+8
| | | | | | | | | | | 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).

* i2c-imx: wait for STOP before disabling controllerMarc Reilly2010-10-011-5/+5
| | | | | | | | | | | 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.

* i2c-imx: fix clear IFF race conditionMarc Kleine-Budde2009-12-091-2/+3
| | | | | | | | | | | | | | | | | | | | | | 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>
