From: Mårten Lindahl <redacted> When the driver starts to send a message with the MASTER_ID field set (high speed), the whole I2C_ADDR register is overwritten including MASTER_ID as the SLV_ADDR_MAS field is set. This patch preserves already written fields in I2C_ADDR when writing SLV_ADDR_MAS. Signed-off-by: Mårten Lindahl <redacted>
Looks good. Is there a Fixes-tag we could apply?
