Subject: [PATCH 0/5] Add support for MSCC Ocelot i2c
Date: Tue, 17 Jul 2018 13:48:32 +0200 [thread overview]
Message-ID: <20180717114837.21839-1-alexandre.belloni@bootlin.com> (raw)
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
