[PATCH v2 dev-5.2 0/2] i2c: aspeed: Add H/W timeout support

[Jae Hyun Yoo]

In case of multi-master environment, if a peer master incorrectly handles
a bus in the middle of a transaction, I2C hardware hangs in slave state
and it can't escape from the slave state, so this commit adds slave
inactive timeout support to recover the bus in the case.

By applying this change, SDA data-low and SCL clock-low timeout feature
also could be enabled which was disabled previously.

Changes since v1:
 - Made it use bus auto recovery feature so that bus can recover itself
   automatically.
