Subject[PATCH v3 3/4] powerpc/fsl: set fsl,i2c-erratum-a004447 flag for P1010 i2c controllers
Date
The i2c controllers on the P1010 have an erratum where the documented
scheme for i2c bus recovery will not work (A-004447). A different
mechanism is needed which is documented in the P1010 Chip Errata Rev L.
