Subject: [PATCH V2 0/5] i2c:ocores: improvements

This patch set provides improvements to the i2c-ocore driver.

[V1 -> V2]
- replaced usleep_range() with udelay() so that the polling version can be
  used in atomic context.
- added dedicated patch for minor style issues
- fixed delay computation
- use spin_lock_irqsave(), instead of spin_trylock_irqsave(). IACK is always
  necessary and a trylock would generate an extra interrupt for nothing
- make the driver ready for an eventual master_xfer_irqless()
