"ARM: SoC fixes for 4.19
Two last minute bugfixes, both for NXP platforms:
* The Layerscape 'qbman' infrastructure suffers from probe ordering
bugs in some configurations, a two-patch series adds a hotfix for
this. 4.20 will have a longer set of patches to rework it.
* The old imx53-qsb board regressed in 4.19 after the addition
of cpufreq support, adding a set of explicit operating points
fixes this."
* tag 'armsoc-fixes-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
soc: fsl: qman_portals: defer probe after qman's probe
soc: fsl: qbman: add APIs to retrieve the probing status
ARM: dts: imx53-qsb: disable 1.2GHz OPP
