i2c: remove i2c driver-model compatibility layer

2019-07-29T21:58:52Z

There are no more users of the compatibility layer for i2c. Remove the driver and all references to it. Signed-off-by: Bartosz Golaszewski Acked-by: Heiko Schocher

i2c: omap24xx_i2c: Adapt driver to support K3 devices

i2c: stm32f7_i2c: Fix warnings when compiling with W=1

xilinx_xiic: Fix transfer initialisation

2019-07-09T05:02:11Z

Prior to starting a new transfer, conditionally wait for bus to not be busy. Reinitialise controller as otherwise operation is not stable. For reference, see linux kernel commit 9656eeebf3f1 ("i2c: Revert i2c: xiic: Do not reset controller before every transfer") hs: Fixed DOS line endings added missing '\n' Fixed git commit description style Signed-off-by: Tomas Melin

xilinx_xiic: Fix fill tx fifo loop

2019-07-09T05:02:11Z

Comparison should be against the actual message length, not loop index. len is used for stopping while loop, pos is position in message. stop should be sent when entire message is sent, not when len and pos meet. hs: fixed DOS line endings Signed-off-by: Tomas Melin

i2c: designware_i2c: Restore enable state after set speed

2019-07-09T05:02:10Z

Before calling __dw_i2c_set_bus_speed(), the I2C could already be set as ether enable or disable, we should restore the original setting instead of enable i2c anyway. This patch fix a bug happened in init function: __dw_i2c_init(){ /* Disable i2c */ ... __dw_i2c_set_bus_speed(i2c_base, NULL, speed); writel(slaveaddr, &i2c_base->ic_sar); /* Enable i2c */ } In this case, enable i2c inside __dw_i2c_set_bus_speed() function will cause ic_sar write fail.

i2c: stm32f7: improve loopback in timing algorithm

2019-05-23T09:36:47Z

This avoids useless loops inside the I2C timing algorithm. Actually, we support only one possible solution per prescaler value. So after finding a solution with a prescaler, the algorithm can switch directly to the next prescaler value.
