[PATCH v2 0/6] Add support for MSCC Ocelot i2c
From: Alexandre Belloni
Date: Tue Jul 31 2018 - 09:47:56 EST
Hi,
Because the designware IP was not able to handle the SDA hold time before
version 1.11a, MSCC has its own implementation. Add support for it and then add
i2c on ocelot boards.
I would expect patches 1 to 4 to go through the i2c tree and 5-6 through
the mips tree once patch 4 has been reviewed by the DT maintainers.
Changes in v2:
- removed first patch as a similar one is in i2c-next
- rebase on top of i2c-next
- Added two patches to implement ideas from Andy
Alexandre Belloni (6):
i2c: designware: use generic table matching
i2c: designware: move #ifdef CONFIG_OF to the top
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
