When building with the igep00x0_defconfig, the following warning is shown:
$ make -j $(nproc) ... LD spl/u-boot-spl OBJCOPY spl/u-boot-spl-nodtb.bin SYM spl/u-boot-spl.sym CAT spl/u-boot-spl-dtb.bin COPY spl/u-boot-spl.bin MKIMAGE MLO ===================== WARNING ====================== This board does not use CONFIG_DM_I2C (Driver Model for I2C drivers). Please update the board to use CONFIG_DM_I2C before the v2022.04 release. Failure to update by the deadline may result in board removal. See doc/develop/driver-model/migration.rst for more info. ====================================================
The only reason why I2C is enabled for the IGEP boards is that the TWL4030 driver requires it.
But both the TWL4034 and the OMAP I2C controller drivers were converted to the driver model by commits daa69ffe3d4d ("drivers: i2c: omap24xx_i2c: adopt omap_i2c driver to driver model") and fb1b7712ad3f power: make most tps drivers and the twl4030 driver compatible with DM_I2C") respectively.
So there's no reason anymore to keep using the I2C legacy API and instead the DM_I2C option could just be enabled.
