Subject[PATCH v3 0/4] P2040/P2041 i2c recovery erratum
Date
The P2040/P2041 has an erratum where the i2c recovery scheme
documented in the reference manual (and currently implemented
in the i2c-mpc.c driver) does not work. The errata document
provides an alternative that does work. This series implements
that alternative and uses a property in the devicetree to
decide when the alternative mechanism is needed.

Chris Packham (4):
dt-bindings: i2c: mpc: Add fsl,i2c-erratum-a004447 flag
powerpc/fsl: set fsl,i2c-erratum-a004447 flag for P2041 i2c
controllers
powerpc/fsl: set fsl,i2c-erratum-a004447 flag for P1010 i2c
controllers
i2c: mpc: implement erratum A-004447 workaround
