* i2c-stu300: I2C STU300 stability updatesLinus Walleij2009-08-20
| | | | | | | | | | | | | | | | | - blk clk is enabled when an irq arrives. The clk should be enabled, but just to make sure. - All error bits are handled no matter state machine state - All irq's will run complete() except for irq's that wasn't an event. - No more looking into status registers just in case an interrupt has happend and the irq handle wasn't executed. - irq_disable/enable are now separete functions. - clk settings calculation changed to round upwards instead of downwards. - Number of address send attempts before giving up is increased to 12 from 10 since it most times take 8 tries before getting through.
