This also works around an issue that imx-i2c driver keeps deferring the probe because of the DMA is not ready. And currently the DMA engine framework can not correctly tell if the DMA channels will truly become available later (it will never be available if the DMA driver is not enabled). This will cause indefinite messages like below: [ 3.335829] imx-i2c 2180000.i2c: can't get pinctrl, bus recovery not supported [ 3.344455] ina2xx 0-0040: power monitor ina220 (Rshunt = 1000 uOhm) [ 3.350917] lm90 0-004c: 0-004c supply vcc not found, using dummy regulator [ 3.362089] imx-i2c 2180000.i2c: can't get pinctrl, bus recovery not supported [ 3.370741] ina2xx 0-0040: power monitor ina220 (Rshunt = 1000 uOhm) [ 3.377205] lm90 0-004c: 0-004c supply vcc not found, using dummy regulator [ 3.388455] imx-i2c 2180000.i2c: can't get pinctrl, bus recovery not supported .....
