[PATCH 0/5] Add support for MSCC Ocelot i2c

From: Alexandre Belloni
Date: Tue Jul 17 2018 - 07:48:44 EST


Hi,

Because the designware IP was not able to the the SDA hold time, MSCC has
its own implementation. Add support for it and then add i2c on ocelot
boards.

I would expect patches 1 to 3 to go through the i2c tree and 4-5 through
the mips tree once patch 3 has been reviewed by the DT maintainers.

Alexandre Belloni (5):
i2c: designware: factorize setting SDA hold time
i2c: designware: allow IP specific sda_hold_time
i2c: designware: add MSCC Ocelot support
mips: dts: mscc: Add i2c on ocelot
mips: dts: mscc: enable i2c on ocelot_pcb123
