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.

i2c: i2c-sh_mobile: calculate clock parameters at driver probing time
i2c: i2c-sh_mobile: optimize ICCH/ICCL values according to I2C bus speed
i2c: i2c-sh_mobile: fix ICCH to avoid violation of the tHD;STA timing spec
i2c: i2c-sh_mobile: support I2C hardware block with a faster operating clock
i2c: i2c-sh_mobile: fix spurious transfer request timed out
