Workaround makes FS as default mode on all affected socs. Add support to check erratum-A005275 validity for an soc. This info is required to determine whether a given soc is affected by this erratum. Add quirk for this erratum "has_fsl_erratum_a005275" . This quirk is used to enable workaround for the errata Force FS mode as default by: - making EPS as FS - setting PFSC bit to disable HS chirping This workaround can be disabled by mentioning "no_erratum_a005275" in hwconfig string Signed-off-by: Chris Packham <judge.packham@gmail.com> Reviewed-by: York Sun <york.sun@nxp.com>
