rockchip: i2c: don't sent stop bit after each message

2019-11-23T14:29:49Z

That's not correct and it breaks SMBUS-style reads and and writes for some chips (e.g. SYR82X/SYR83X). Stop bit should be sent only after the last message. Signed-off-by: Vasily Khoruzhick Reviewed-by: Kever Yang

i2c: mxc_i2c: Remove i2c_idle_bus from probe

2019-08-27T04:20:23Z

i2c_idle_bus is already used in i2c_init_transfer. So before each transfer if the bus is not ready, the i2c_idle_bus will be used to force idle. It is unnecessary to call it again in probe. We found a issue when enabling i2c mux with the mxc_i2c. The mxc_i2c is probed after mux probing. However, at this moment the mux is still in idle state not select any port. So if we call i2c_idle_bus in probe, it will fail and cause mxc_i2c probe failed. Signed-off-by: Ye Li

i2c-mux-gpio: Fix GPIO request flag issue

When requesting GPIO, the GPIOD_IS_OUT is missed in flag, so the GPIO is set the input mode not output and cause mux not work. Signed-off-by: Ye Li
