The operation should be OR, not BIT OR. Signed-off-by: Peng Fan Cc: Heiko Schocher Cc: Stefano Babic

i2c: lpi2c: do not add 4 for bus seq

2018-01-16T05:58:59Z

The number 4 is dedicated on i.MX7ULP, but lpi2c will be reused on i.MX8, 4 is not valid. The seq number could be configured by alias node. The following patch will use i2c4 as the begin for i.MX7ULP. Signed-off-by: Peng Fan

i2c: at91_i2c: remove the .probe_chip function

2017-12-07T08:29:19Z

The .probe_chip function is supposed to probe an i2c device on the bus to determine whether a device is answering to a particular address. at91_i2c_probe_chip() did not do anything resembling this and always returned 0. It looks as though at91_i2c_probe_chip() was intended to be a .probe function for the controller, as it was copied-and-pasted to become at91_i2c_probe() in 0bc8f640a4d7ed. Removing the at91_i2c_probe_chip() function makes the higher layer (i2c_probe_chip()) try a zero-length read transfer to test for the presence of a device instead, which does work.

i2c: at91_i2c: Wait for TXRDY after sending the first byte

2017-12-07T08:28:58Z

The driver must wait for TXRDY after each byte is pushed into the i2c FIFO before pushing the next byte. Previously this was not done for the first byte, causing a race condition with zeros sometimes being sent for the next byte (which is typically the first actual data byte).

i2c: meson: fix return codes on error

2017-12-07T08:28:31Z

Change meson_i2c_xfer_msg() to return -EREMOTEIO in case of NACK, as done by other drivers. Also, don't change the return error in meson_i2c_xfer(). Signed-off-by: Beniamino Galvani Reviewed-by: Simon Glass Reviewed-by: Heiko Schocher

i2c: meson: reduce timeout

2017-12-07T08:28:21Z

The datasheet doesn't specify a suggested timeout and 500ms seems very long: reduce it to 100ms. Signed-off-by: Beniamino Galvani Reviewed-by: Simon Glass Reviewed-by: Heiko Schocher

i2c: rcar_iic: Add RCar IIC driver

2017-11-30T01:32:34Z

Add driver for the RCar IIC or DVFS I2C controller. This driver is based on the SH I2C driver, but supports DM and DT probing as well as modern I2C framework API. Signed-off-by: Marek Vasut Cc: Nobuhiro Iwamatsu
