Cover letter [PATCH 0/5] i2c-sh_mobile non-urgent changes
Hello,
This is the first batch to fix the i2c-sh_mobile driver. As a first step, this comprises of the SCL optimization work and a simple fix to annoying spurious WAIT interrupt issue; in other words, this does not change tx/rx data handling logic.
This driver has an architectural problem with send/receive procedures and needs a fundamental overhaul. I've been working on splitting into logical chunks, but not yet completed.
Patches are prepared against the vanilla v3.6. I don't have a chance to give it a try with v3.6+ kernels myself, but tend to be optimistic about that. I have been cooking these patches over a year, and they work perfectly fine with older kernels ..v3.4 so far.
