How you tested both NXP's powerpc and ARM platforms as fsl i2c is yet to
move to DM model?
Or my understanding is wrong.
I only tested on powerpc (preciser socrates_defconfig) platform ...
But I see that now in current mainline there is applied a change in
drivers/ddr/fsl/main.c from commit:
commit 0eba65d2013e5517e70cc9b3d467ba8183b54cd9
Author: Chuanhua Han <chuanhua....@nxp.com>
Date: Wed Jul 10 21:00:20 2019 +0800
boards: lx2160a: Add support of I2C driver model
DM_I2C_COMPAT is a compatibility layer that allows using the non-DM I2C
API when DM_I2C is used. When DM_I2C_COMPAT is not enabled for
compilation, a compilation error will be generated. This patch solves
the problem that the i2c-related api of the lx2160a platform does not
support dm.

Which does some similiar change ... but I think this already applied patch
introduces more ifdefs and code ...
Hmm.. just tried to compile U-Boot for the socrates board (with DM
changes) without my patch ... I get compilererror:
/home/hs/data/Entwicklung/abb/uboot-rework/u-boot/drivers/ddr/fsl/main.c:

My bad. I only tested build/run on NXP's ARM platforms.
As I am working on PowerPC pull request, I missed it.
Ok, fixed this fast and dirty with:
diff --git a/drivers/ddr/fsl/main.c b/drivers/ddr/fsl/main.c index

#ifndef CONFIG_DM_I2C
i2c_set_bus_num(CONFIG_SYS_SPD_BUS_NUM);
and now code compiles and after flashing U-Boot I see:

So this works also for me ...
Hmm... the change from commit
0eba65d2013e5517e70cc9b3d467ba8183b54cd9
doubles code for DM and none DM case ... I don;t like this.
May you can look through my rebased patch [1] and may test it ?
If this is OK, I can send it as a v2.
bye,
Heiko

Please send v2 version. I will test on both ARM and PowerPC platforms
And also get reviewed from internal IP owners . .
Ok, started travis build, if it is fine, I send the v2.
