Subject: I2C_IMX support for i.MX8MP
Date: Wed, 17 Aug 2022 12:38:53 +0200	[thread overview]
Message-ID: <YvzFPR5rwVSLzNPK@skidata.com> (raw)

Hi list,

Just found out about this imx ML and I'm not sure if it is also intended
for questions, but I'll give it a try. Please correct me if I'm wrong.

We are currently in the process of creating a BSP for a custom i.MX8MP
based board which features 3 I2C busses. Unfortunately I'm currently
unable to get them to live with the i2c-imx or i2c-imxlpi2c drivers.
Using i2c-gpio (with adapted SW_MUX_CTL and unchanged SW_PAD_CTL)
works fine.

I'm aware of ERR007805 and tried therefore to configure the busses to
200kHz, but I don't get any signals/edges on the pins.

So the basic question for me is (as I was unable to find any trustworthy
answers on the net) if the i2c-imx driver supports the i.MX8MP at all?

Any feedback is warmly welcome!

regards;rl

P.S. All tests were done with mainline linux 5.19.y.

P.P.S I've also sent this mail to linux-imx@nxp.com before.
