[PATCH v3 0/2] Qualcomm Universal Peripheral (QUP) I2C controller

From: Bjorn Andersson
Date: Fri Jan 17 2014 - 18:04:14 EST

Continuing on Ivans i2c-qup series.

Changes from v2:
- Removed unused variables and includes
- Corrected read logic in irq handler
- Made the polling loop in qup_i2c_poll_state() less arbitrary
- Only building suspend/resume if CONFIG_PM_SLEEP

Changes from v1:
- Cleaned up device tree binding example.
- Refrased device tree bindings.
- Following changes in the i2c framework.
- Use the core clock to calculate divider for the bus clock, instead of
explicitly setting it.
- Remove explicit pinctrl settting.
- Split/renamed qup_i2c_enable(bool) into enable/disable functions.
- Return value was overwritten on error in write_one/read_one.
- Initialize the i2c core every time, so that we actually can execute
more than 1 transmission per xfer.
