Hi,
This is a set of I2C fixes. Its primary purpose is to deal with the
I2C spurious IRQ problem:
Spurious irq 95: 0xffffffdf, please flush posted write for irq 56
It seems to work: under constant I2C load, no spurious IRQ messages
showed up after several hours of testing. (Without these patches,
spurious IRQs usually show up in a few minutes.) Some of the code has
also been cleaned up.
Any feedback on how this series works for others is appreciated.
Tested on N800, Beagle and 3430SDP.
- Paul
