Some slow I2C devices like Power Monitor(ZM7304) at times do not work well with low timeout value, so I2C bus get stuck during read cycle with this device, changing it to 100ms from 10ms works fine
A lot of other i2c drivers like mxc and i2c drivers of BOOTROM also use relax timeouts to give sufficient ticks to work well with slower devices
