This series contain two patches, first is to optimize Mediatek I2C driver to use WRRD if hardware support auto restart. Because auto restart will issue auto restart interrupt, change to use WRRD can reduce interrupt latency. The second is to fix multi transfer error in high speed mode. If hardware support auto restart, need driver to send master code first. Change in v2: fix i2c checkpatch error.
