This patch set provides improvements to the i2c-ocore driver. [V2 -> V3] - fix error condition on platform_get_irq(). Copied from https://patchwork.ozlabs.org/patch/1038409/
[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()
