[PATCH] mfd: intel-lpss: Add default I2C device properties for Apollo Lake

2016-09-12 Thread Jarkko Nikula
Default I2C device properties for Intel Broxton, especially SDA hold time may not be enough on Intel Apollo Lake. These properties are used in case we don't get timing parameters from ACPI. The default SDA hold time for Broxton may fail with arbitration lost errors on Apollo Lake: i2c_designwar
